Demonstrates how electricity can be produced from magnets through various experiments ... magnets can induce electric currents in coils of wire, illustrating the relationship between magnetism ...

It is awesome. Michael Faraday conducted many brilliant and meticulous experiments and, in 1831, he discovered that a magnet passing through a coil of copper wire caused an electric current to ...

If you drop strong magnets onto a plate of copper, something remarkable happens: the magnets slow down before hitting the surface and appear to levitate slightly, like the copper is another magnet ...

All that’s needed is some coiled copper wire, a battery and magnets thin enough to fit through the coils. The magnets snap onto both ends of the battery. Put the battery inside the coil and ...

Dangerously Fun has a guide to build a homopolar motor from a battery, copper wire, and magnet. A homopolor motor doesn’t rely on electromagnets in an armature changing their polarity to force a ...

Some kinds of batteries produce electricity by a chemical reaction between two different metals (electrodes) immersed in acid (electrolyte). Figure out how to make your own batteries in case the ...
