Yes, everyone loves springs. But a mass hanging vertically on a spring is a great example of stable equilibrium. Why does this produce stable equilibrium? Let's start with a diagram of a mass hanging ...

Magnetic levitation sounds like a magic trick, but it’s pure science. Objects can be made to “levitate” by using the repelling power of the opposite poles of magnets. By applying forward motion, the ...

Most of our readers are already going to be familiar with how electromagnets work — a current is induced (usually with a coil) in a ferrous core, and that current aligns the magnetic domains present ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...

The idea of levitating off the ground has been a staple of science fiction dreams and human imagination since time immemorial. While we don't have our hoverboards just yet, we do have the very real ...
