Question

State whether True or False :

Lenz's law defines the polarity of the induced voltage.

• A. True
• B. False

Answer 1

The correct option is A True

Lenz's law defines the polarity of the induced voltage.

When a voltage is generated by a change in magnetic flux according to Lenz's Law, the polarity of the induced voltage is such that it produces a current whose magnetic field opposes the change which produces it. If it is decreasing, the induced field acts in the direction of the applied field to oppose the change.
