Electromagnetic Induction

Question 1

What is Magnetic Flux Linkage?

Answer 1

The magnetic flux linkage through a loop is the product of the magnetic flux through the loop and number of turns of wire in the loop

Question 1

What is Magnetic Flux?

Answer 1

The magnetic flux through a plane surface is the product of the component of the magnetic flux density normal to the surface and the area of the surface.

Question 2

What is the Faraday’s Law?

Answer 2

Faraday’s Law states that the magnitude of emf induced is directly proportional to the rate of change of magnetic flux linkage.

Question 3

What is the Lenz’s Law?

Answer 3

Lenz’s law states that the emf is induced in the direction such as to oppose the change in the flux linkage that is inducing it.
