Description : What is Lenz's formula ?

Last Answer : The lens formula is an easy way to understand how the electromagnetic circuit complies with Newton's 3rd law and energy conservation law. Lenz's law is named after Henrik Lenz. It is said ... force increases the current all the time, and its magnetic field opposes the actual magnetic field.
