Both assertion and reason are true.
Explanation:
- According to Lenz law, the current induced in an electrical circuit is capable of opposing the cause that produced the current.
- An extra force or effort is required to work against the external force.
- Due to extra effort or force, a magnetic flux is induced which as a result induces more current in the circuit.
- Thus the transformed electrical energy obeys the law of conservation of energy.
