A small circular loop is suspended from ...

A small circular loop is suspended from an insulating thread. Another coaxial circular loop carrying a current `I` and having radius much larger than the first loop starts moving towards the smaller loop. The smaller loop will

A

be attracted towards the bigger loop

B

be repelled by the bigger loop

C

experience no free

D

All of the above

Text Solution

Verified by Experts

The correct Answer is:
B
From Lenz's law, induced effects always oppose the cuse due to which they are produced. So, when the first loop is moved towards the smaller loop it wil face repulsion.

A circular loop of radius r carrying a current i is held at the centre of another circular loop of radius R(>> r) carrying a current I. The plane of the smaller loop makes an angle of 30^@ with that of the larger loop. It the smaller loop is held fixed in this position by applying a single force at a point on its periphery, what would be the minimum magnitude of this force?
