Electromagnetic Induction

Question 1

Magnetic flux Density

Answer 1

A representation of the magnitude and direction of the magnetic field.

Question 2

Magnetic flux linkage

Answer 2

The product of the number of turns on the coil and the flux through the coil.

Question 3

Faraday’s law of electromagnetic induction

Answer 3

The Emf induced is directly proportional to the rate of change of magnetic flux.

Question 4

Lenz’s Law

Answer 4

The induced current flows in a direction so as to set up a magnetic field to oppose the change in magnetic flux.
