Building the electromagnetic coil gun. The simplified edition is very cheap and easy to build (and requires no explosive propellant!). The following circuit is what I designed and built: Electronics ...

Remember that when the supply is switched off, the magnetic field will tend to collapse and in doing so will generate a back EMF (BEMF) or counter EMF (CEMF) in the electromagnet coil windings. If ...

The electromagnetic force generated by the current moving through the coil pushes against the magnets attached to the battery, pushing the battery along the way. [Amazing Science] plays with the ...

State-owned arms maker China South Industries Group (CSGC) has released footage of its electromagnetic coil gun. Allegedly capable of firing 3,000 rounds per minute, the prototype represents a ...

I was gifted one of those, in the later~mid 1960’s. Coil of at the bottom of frame along with the “D” cell holder. Chunk of (rough cast appearance) material on the pendulum.

So I built a buzz coil, a project derived from the ignition on a Model T that you can toss together to satisfy all your sparking needs with a just a few common automotive parts. Search for: Science ...

To achieve that intensity, Takeyama and his team pump megajoules of energy into a small, precisely engineered electromagnetic coil, the inner lining of which then collapses on itself at Mach 15 ...

The GR-1 Anvil electromagnetic rifle An electromagnetic rifle, which propels a steel projectile using electromagnetic coils, is now being offered for pre-order in the US by Arcflash Labs, a Los ...

Clutches and brakes with an electromagnetic interface offer definite advantages, including accurate engaging and clean releasing. Besides being quick, they also run cooler and cleaner, with the ...
