If a current is passed through a spring then the spring will

A

expand

B

compress

C

remains same

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
(b) When current is passed through a spring then current flows parallel in the adjacent turns.
NOTE : When two wires are placed parallel to each other and current flows in the same directions, the wires attract each other.
Similarly here the various turms attract each other and the spring will compress.
