    How exactly does it work?

    According to [tex]\nabla \times E = -\partial B / \partial t[/tex], a time-varying magnetic field induces a divergence-free E field; where this intersects a metallic conductor it results in eddy currents and ohmic heating. The magnetic field can be generated by running alternating current through a solenoid.

    Then there's a different mechanism that relies on ferromagnet hysteresis loops.
