A magnetic needle placed near a current carrying conductor deflects due to the

A

heating effect of electric current.

B

magnetic effect of electric current.

C

chemical effect of electrical current.

D

Both (b) and (c)

Text Solution

Verified by Experts

The correct Answer is:
B
A magnetic needle placed close to a current carrying conductor deflects due to the magnetic effect of the electric current. Because the magnetic needle (or its field) interacts with the magnetic field produced by the current carrying conductor it deflects.
