Eddy currents are currents induced in conductors to oppose
the change in flux that generated them. It is caused when a
conductor is exposed to a changing magnetic field due to
relative motion of the field source and conductor, or due
to variations of the field with time. This can cause a
circulating flow of electrons, or a current, within the
body of the conductor. These circulating eddies of current
create induced magnetic fields that oppose the change of
the original magnetic field due to Lenz's law, causing
repulsive or drag forces between the conductor and the
magnet. The stronger the applied magnetic field, or the
greater the electrical conductivity of the conductor, or
the faster the field that the conductor is exposed to
changes, then the greater the currents that are developed
and the greater the opposing field.
