Question

(ii) As shown in figure a coil is suspended. A bar magnet is moved perpendicular to
the plane of coil with North Pole pointing the coil.
A) What is the change in magnetic flux in coil?
B) What is the direction of induced current in coil with respect to bar magnet?
C) Draw magnetic field lines at the end of bar magnet and induced field in the coil.
D) Explain the reason for induced current.​

Answer 1

The magnetic flux linked with the coil change factors are given below:

• The change in the magnetic flux in coil depends upon the moving towards and away the coil.
• As it moves towards the coil then magnetic flux increases and away from  it decreases the magnetic flux.
• The direction of the induced current is inward when the magnet is moving away form the coil and vice versa.
• The reason of the induced current is explained by the faraday's law.
• As long as the change in the magnetic flux will change the emf.
