Assertion: The earth's magnetic field does not affect the working of a moving coil galvanometer.
Reason: Earth's magnetic field is very weak.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
In a moving coil galvanometer, the coil is suspended in a very strong uniform magnetic field created by two magnetic pole pieces. The earth's magnetic field is quit weak as compared to that field, therefore, it does not effect the working of magnetic field.
