When a closed loop of wire cuts through magnetic flux lines, a current is induced into the loop. The current in the loop sets up a magnetic field that is in opposition to the original magnetic flux. This is essentially _____.
A) Coulomb's law
B) Ohm's law
C) Lenz's law
D) Weber's law

This phenomenon is described by Lenz's Law, which states that the direction of the induced current in a closed loop will be such that it opposes the change in magnetic flux that produced it.
