We see our share of pitches for perpetual motion machines in the Hackaday tips line, and we generally ignore them and move along. And while this magnetic levitation motor does not break the laws ...

Whenever the circuit was closed both D lines were seen to widen. Since one might attribute the widening to the known effects of the magnetic field ... to the lines of force. The light of an ...

THE statement that “the mechanical force which urges a conductor carrying a current across the lines of magnetic force, acts, not on the electric current, but on the conductor which carries it ...

A high-speed levitating motor showcases the incredible power of magnetism in motion. Suspended effortlessly, it spins at remarkable speeds, creating a mesmerizing display of precision and balance.

The closer together the lines are, the stronger the magnetic force. Can you see the magnetic force is strongest at the opposite ends of the magnet? A whole range of metals we use in the home ...
