A circular loop carrying a current I is ...

A circular loop carrying a current `I` is placed in the xy-plane as shown in figure. A uniform magnetic fied `B` is oriented along the positive z-axis. The loop tends to

A

expand

B

contract

C

rotate about x-axis

D

rotate about y-axis

Text Solution

Verified by Experts

The correct Answer is:
A
From fleming's left hand rule, we can see that magnetic force is outwards on the loop.

so it tends to expand.
