Lenz's law - need clarification

  1. Nov 1, 2006 #1
    I only understand Len'z law for a current induced in a single loop... however I don't for in a coil... What does the relative poisition of the manetic poles of the magnet and the coil respectively has to do with the direction of the current?

    A coil is just multipe loops. If you understand what happens for a single loop, it happens N times as much for a coil of N turns. The direction of the current in each loop of the coil is the same as for a single loop. The induced emf is additive, so the total voltage is N times the voltage of a single loop. If the only resistance is external to the wire, the current will also be N times the current for a single loop.
