An Intiative by Sri Chaitanya

The direction of the induced emf is such that it opposes the change in flux

The magnitude of the induced emf is directly proportional to the rate of change of flux

The magnitude of the induced emf is inversely proportional to the rate of change of flux

The magnitude of the induced emf is directly proportional to the square of the rate of change of flux.

Detailed Solution

According to Faraday's second law of electromagnetic induction, the intensity of the induced emf is inversely related to the flux change rate.
According to Faraday's second law of electromagnetic induction, the coil's flux connections vary at a pace that determines how much-induced emf is produced. The number of turns and the flux connected to the coil are multiplied to create the flux connections.

The amount of induced e.m.f. is inversely proportional to the magnetic flux associated to the circuit's negative rate of variation.
