Question

explain lenz's law considering a closed conducting coil and a bar magnet​

Answer 1

Faraday's law of induction states that when the magnetic flux through a closed conducting loop changes in time, an emf is induced in that loop: ε induced = − d Φ B d t . ... According to Lenz's law, the direction of the induced current and resultantly the induced magnetic flux opposes the original magnetic flux.

Answer 2

Explanation:

The solenoid is a long coil containing a large number of turns of insulated copper wire

The magnetic field produced by a current carrying solenoid is similar to a magnetic field by a bar magnet
