Foucault currents (also called Eddy currents) are electric currents induced within conductors by a changing magnetic field in the conductor. These circulating eddies of current have inductance and thus induce magnetic fields. These fields can cause repulsion, attraction, propulsion, drag, and heating effects. The stronger the applied magnetic field, the greater the electrical conductivity of the conductor, and the faster the field changes, the greater the currents that are developed and the greater the fields produced.
