A coil of copper wire is connected to galvanometer. What would happen if a bar magnet is:
a.Pushed into coil.
b.Withdraw from the coil
c.Held stationary inside the coil
Answers
In case A and B there will be deflection in Galvanometer as there will be flow of electricity due to induction.
Induction of electricity happen for moving magnetic field.
In C there will be no flow of current, hence no defection in Galvanometer.

A coil of copper wire is connected to galvanometer. What would happen if a bar magnet is:
A) pushed into coil.
An induced current is produced in the coil. The current will flow in anticlockwise direction.
As a result, the Galvanometer will show deflection.
B) withdraw from the coil.
An induced current is produced in the coil. The current will flow in clockwise direction.
As a result, the Galvanometer will show deflection.
C) held stationary inside the coil.
No current is produced in the coil. The Galvanometer will show zero deflection.
