<p>induced in it by the <a href="page.php?w=magnetic_field">magnetic field</a>, as described by <a href="page.php?w=Faraday%27s_law_of_induction">Faraday's law of induction</a>.  By <a href="page.php?w=Lenz%27s_law">Lenz's law</a>, the circulating currents create their own magnetic field that opposes the field of the magnet.  Thus the moving conductor experiences a drag force from the magnet that opposes its motion, proportional to its velocity.  The <a href="page.php?w=kinetic_energy">kinetic energy</a> of the moving object is dissipated as <a href="page.php?w=Joule_heating">heat</a></p><p>
