Question

Write the mathematical expression of Faraday’s law of induction?​

Answer 1

Answer:

The induced current produces a magnetic field, which opposes the change in the magnetic flux. The magnitude of the induced emf can be calculated using Faraday's law. The magnetic field inside the long coil is B = μ0(N/ℓ)I. ... The induced emf is emf = -L*∆I/∆t, where the minus sign is a consequence of Lenz's law.

Answer 2

Answer:

Explanation:

If the number of magnetic lines of force passing

through the coil changes, current is induced in the

coil. This is known as Faraday’s law of induction.

The current produced in the coil is called the

induced current.
