how to make a railgun with magnets

With the magnets facing the same direction as the original design, repeat with another stack of magnets right next to the first stack. 1). This discharge rate depends on the time constant; the bigger the time constant, the longer the capacitor will hold its charge. They will start to accelerate immediately. Video transcript available here. apach3 Mar 1, 2007. yeah i'm no scientist, but i understood it so that it works with an electric magnet that pulls and then pushes the bullet, i might have gotten … /22. It shoots various items as ammunition. A railgun is a device that uses magnetic forces to accelerate a projectile to extremely high speeds. Again, wait for it to dry and repeat until the row of magnets reach the length of the rails.

The magnetic field is induced with very strong neodymium magnets. At the top of the ramp it falls, converting magnetic attraction into kinetic energy. The transition from the perspex rails to the aluminium rails needs to be smooth so sand it … NOTE: You may need to use a bigger ferrite bead to increase the weight of the projectile if it ends up flying off when it is fired. Each set of parallel-connected capacitors will have a total capacitance of 940uF. These simple observations form the backdrop for the rest of this section. On my channel you will find all the ways to have fun with magnets divided into 3 main categories: Classical magnetic experiments such as magnetic levitation, homopolar motors, small magnetic weapons, Gauss cannons, gears, magnetic field viewers and much more. Sphere K-40-C https://sumag.net/k-40-c-x01, LIKE & SUBSCRIBE HERE: http://bit.ly/Sub2MagneticGames The railgun is a kind of the electromagnetic gun (see Fig. https://twitter.com/magneticgamesIT. x 3/4” thick ring. Place the ferrite bead on a flat surface and fill half of the bead with silicone sealant and wait for it to dry. This is a revised version of the project SMOT (Simple Magnetic Overunity Toy) Add Tip Ask Question Comment Download. Continue wrapping the wire around the pen until 1–2 in (2.5–5.1 cm) are covered with the wire. Cool enough for a +fav. The armature is an integral part of the projectile assembly. There are no magnets in railguns. All ways to have fun with magnets. The armature bridges the gap between the rails. It is also accelerated, and hits with a higher velocity V 2. NOTE: 3 capacitors may not be enough to hold the charge, you can add more to your liking. We decided to make the rails 6 inches long and relatively thin, so that the armature could have a "runway" along which to accelerate. The Railgun is a ranged weapon added by Immersive Engineering. Basics. At this point, we don’t know whether the magnetic force is directed upwards or downwards. Again, wait for it to dry and repeat until the row of magnets reach the length of the rails. Thanks to Supermagnete.com for giving me these magnets for free. Keep magnets out of reach of small children and pets. IMPORTANT: do not touch the ends of the power cord or you will get electrocuted. Somehow we decided to make a miniature railgun but then we got stuck :( Here're the components we have: > A pcb/circuit board consisting of … Place the meter stick under and between the 2 rails with the … This diagram illustrates the direction of the Lorentz force with the use of the right-hand rule. WARNING: Read "IMPORTANT" steps so that you won't hurt yourself or get electrocuted if you decide to make the improved version of the railgun. As the image shows, the current forms a magnetic field directed into the page. Make sure that the magnets do not touch the copper wires since this will again, short the rails. i used a hammer, but it is probably better to file them down. Cut out 2 small circles from the cardboard and poke a hole into the center of the circle. Make sure each magnet touches the paper clip. The armature is an integral part of the projectile assembly. Using 2 alligator clips, connect the ends of the power cord to one transformer at 0 and 120. You would do better to make a railgun with electromagnets. This will also tell you the direction of the magnetic force. Rounds fired from a railgun are extremely quick, effortlessly cutting through armor. There we will show some … Here's how to build one and how it works: Permanent magnet guns, or PMGs, … Use the same number of capacitors for each of the parallel connected sets of capacitors (example: if 3 capacitors are chosen to be connected in parallel in the picture below, connect the series with sets of 3 parallel-connected capacitors with a total of 6 capacitors). The fast switching requirement is because you need to switch off any magnetic field behind the bullet, or you'll slow it down. The railgun is a kind of the electromagnetic gun (see Fig. My Channel offers you curious experiments and fun games to do with magnets. It can be a solid piece of conductive metal or a conductive sabot-- a carrier that houses a dart or other projectile.Some rail guns use a plasma armature. Facebook The 2 inch rod will now move. Real VO2Max--Measure Your Athletic Potential, Simple Extruded Aluminum Frame for LED Panels. The function is similar to a railgun (linear), but it is obvious that with a circular arrangement, such acceleration … The direction of the movement can be determined by the forces described above using the right-hand rule. This isn't a thing we normally recommend doing with magnets--it's not their primary use! Make sure that the magnets do not touch the copper wires since this will again, short the rails. I don't remember if they used neodymium magnets, as I was too excited to read the article closely enough, but in the first issue of MAKE (check your local massive bookstore - it might still be on the shelf in the computer section) they showed how to make a model railgun with magnets and stainless steel balls. Place the meter stick under and between the 2 rails with the magnets on the opposite side. A coilgun uses a … Voir plus d'idées sur le thème Moteur … Step 2: How It Make . The railgun doesn't use permanent magnets.

This will create a short on the rails, but this is where we want the electric charges to flow. A current is induced in the wire by the moving magnetic field. If you did not use a compass to determine the direction of the magnetic force, you can easily change the direction of the propelling rod by swapping the connections to the battery terminal. In this set-up a thin metal foil is placed on the back of a non … Try not to bend the wires when you bring them home so that you can straighten them out as the ‘rails’. Make sure the coils are tightly wrapped and don’t overlap. This was initially meant to make the railgun stronger, but in hindsight was unnecessary. The input voltage … All ways to have fun with magnets. Connect them in parallel by connecting the negative post of one capacitor to the negative post of the next. So hopefully someone will make proper correction to the page with good reference to the actual design. Repeat with the positive post.

For the bravest here are the magnets I used in this experiment. The concept of a railgun consists of propelling a conducting object along 2 conducting rails due to a magnetic force and an electric force. Remove one of the connections of the alligator clip from the 12V battery terminal. In the theoretical SMOT design, a steel ball is pulled up a ramp by an array of permanent magnets. This will allow the magnets to stick flat to the ends of the wire axle. This page is about the Railgun added by Immersive Engineering. Do not touch the ends of the alligator clips connected to the transformer either. We made a ¾” thick ring magnet by stacking three RZ0X84 magnets together, forming a 3” O.D. Blueprint: Dimensions: We decided to make the rails 6 inches long and relatively thin, so that the armature could have a "runway" along which to accelerate. The idea is that the device will work as demonstration of forces behind an electric motor, so I don't require high speed for the bar. All ways to have fun with magnets. Rail guns leave gunpowder-based weapons in the dust (one can hit a target 250 miles away in six minutes). Electromagnets can be used to generate very large fields, even stronger than a permanent magnet, around the rails. Maybe I should also point out that there is a difference between a railgun and a coilgun. Thanks to Supermagnete.com for giving me these magnets for free. The point of a railgun is to make ballistic weaponry even more lethal -- to give a round greater penetrative ability and to cause more damage to a target. To charge these capacitors, we apply 450 volts to them using the power supplied from the wall socket. The railgun in its simplest form differs from a traditional electric motor in that no use is made of additional field windings (or permanent magnets). Make sure that the wire is long enough to keep its contact with the rails. In this example, 2 sets of parallel-connected capacitors are connected in series for a power source of 900 volts. How much of the stored energy is transferred to the kinetic energy of the projectile? It's very easy to make, you need some magnets , some steel … The strength of the magnets is scientifically explainable but there's something "magical" in its interaction with the world. For many years, the utility of electromagnetic guns has been explored. As the top magnet gets stronger and farther away from the floating magnet, the area where the floating magnet can be stabilized increases. If so, then I see no reason why you couldn't do this, just make sure the magnet projectile has a strong enough magnetic field, and the mass is small enough so that you get the desired acceleration. Since the neodymium magnets consist of a north pole on one side and a south pole on the other side, stack the faces up. The reason railguns don't work are because we can't accelerate them hard enough. This is a revised version of the project SMOT (Simple Magnetic Overunity Toy) Add Tip Ask Question Comment Download. The force of the impact is transmitted through the magnet and two ball bearings, causing the second one to shoot at the second magnet. However; your model would make a good railgun, and you would get a heck of a light show when firing it! The force imparted on the projectile (the “power” of the gun) is related to these two things. This field interacts with the current to produce the … Prop them up with something that doesn’t conduct electricity so that they won’t short. Firing the railgun To fire the railgun, just drop the wheels on the rails. If the filing is done carefully to make the flat ends perpendicular to the wire, then there will be less wobbling as the magnets travel down the rails. Reconnect the alligator clip to the 12V battery terminal and the wire will shoot. Also there is no reason to use permanent magnets. NOTE: You can connect the capacitors in series (negative post to positive post) to increase the voltage of the power source created. Homemade Railgun | Magnetic Games Copper is chosen as it is a good conductor of electricity. IMPORTANT: it is really hard to handle these magnets and if they smash into each other, they will easily shatter and break. Step 4: Finished!! For other uses, see Railgun. No glue is necessary, as the magnets are very strong. The railgun in its simplest form differs from a traditional electric motor in that no use is made of additional field windings (or permanent magnets). I used 6x20mm aluminium, and 6mm perspex. The Railgun does not need to be loaded; it will automatically grab ammunition from items in the inventory. I think the page is not doing the theory behind railgun justice. This may be a little difficult since the magnets will oppose each other. Each frame shows 1/30th of a second. With the magnets facing the same direction as the original design, repeat with another stack of magnets right next to the first stack. While permanent magnet guns are fascinating, I have to warn visitors that they are never going to represent a threat to world peace. It's practically useless to use a railgun for a shot that would fit in anything much bigger than what would fit into a 2m gun, because at that point, it's far more efficient to use gunpowder without the rails. Using the exacto knife, cut away the plastic cover of the copper wire. Test the voltage from the ends of the alligator clips connected to the ends of the second transformer with the multimeter at a setting above 450V AC (squiggly line next to the V, not the straight line). But the speed does not add up linearly. I'm creating a permanent magnet railgun, which essentially uses two conducting rods with a row of magnets between them and a conducting projectile laying across the two rods. This will again multiply the voltage by 1.8 giving a total of 3.6. if it goes the wrong … I held them in place with the two rulers. If we have 4 magnets, the kinetic energy is 4, but the speed goes up as the square root of the kinetic energy. Wait for it to dry. Since the neodymium magnets consist of a north pole on one side and a south pole on the other side, stack the faces up. Satisfaction video like the construction of magnetic sculptures, slime and magnetic putty and product review. Using 2 more alligator clips, connect the ends of the clips to the other end of the transformer at 0 and 220. Again, this can be confirmed with the illustration of the right-hand rule. Connect the free ends of the alligator clips, one to the negative end of the 12V battery terminal and one to the positive end. For the few that may not know already, a railgun is an electrically powered electromagnetic projectile launcher. In thefirst frame, a steel ball starts rolling towards a magnettaped to a wooden ruler. Sep 6, 2016 - Explore Ben Gatien's board "Magnets" on Pinterest. I am trying to determine the efficiency of this setup, so I would like to calculate the total theoretical energy going in to making the projectile move.
