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, ...

Lenz’s Law is one of those physics tricks that look like magic if you don’t understand what’s happening. [Seth Robinson] was inspired by the way eddy currents cause a cylindrical neodymium magnet to ...

Natural crystals fascinate with their vibrant colors, their nearly flawless appearance and their manifold symmetrical forms. But researchers are interested in them for quite different reasons: Among ...

In this video I experiment with Lenz's Law And Faraday's Law of Induction to generate electricity and magnetic force fields in copper.
