Question

A coil is hung as shown in the figure. A bar magnet with north pole facing the coil is moved perpendicularly

a) How does the magnetic flux passing through the coil change? 

b) State the direction of the flow of the current induced in the coil, keeping the direction of bar magnet in view. 

c) Draw the diagrams showing the magnetic field formed due to bar magnet at the surface of the coil and the magnetic field formed due to induced current. 

d) Explain the reason for induced current.

Answer 1

a) A bar magnet with north pole facing the coil is moved perpendicularly, the magnetic flex increases when passing through the coil. 

b) The direction of the flow of the. current induced in the coil, keeping the direction of bar magnet is anticlockwise due to north pole. KT 

c) Φ = 0

Plane of coil is parallel to ‘B’. 

d) Electromagnetic induction is the reason for induced current.
