Question

Lenz’s law is a consequence of the law of conservation of

• A. Charge
• B. Mass
• C. Energy
• D. Momentum

Answer 1

The correct option is C

Energy

Explanation:

1. Lenz's law is based upon the law of conservation of energy.
2. This law states that the induced current always tends to oppose the cause which produces it.
3. So in order to do work against opposing forces, we have to put extra effort.
4. This extra work leads to periodic changes in magnetic flux hence more current is induced.
5. So the extra effort is just transformed into electrical energy which is the law of conservation of energy.

Hence, the correct option is option C.
