In electromagnetism Lenz' law states that a time-dependent change in magnetic induction B opposes B. According to Faraday's law the time derivative of B
induces a current iind into a conducting loop. The direction of iind is such that the field B is opposed. Recall here that the direction of current i and field B are connected through the right-hand screw rule. The screw is driven into the direction of B and rotated along i.
The law is named for the Estonian physicist Heinrich Friedrich Emil Lenz (1804 – 1865).
