Magnetism Question

Question

A rectangular loop carrying current i is situated near a long straight wire such that the wire is parallel to one of the sides of the loop and the plane of the loop is same of the left wire. If a steady current I is established in the wire as shown in the figure the loop will

Answer 1

The steady current I will move towards the wire

Correct Answer is (C)

Explanation:

Wires placed close to each other carry current in the same direction and hence attract. Wires placed far apart carry current in opposite direction and hence repel each other. But here attraction is strong and repulsion is weak. So, loop moves towards the wire.

Comments

So incase if the wires repel than there is no chance of movement as in case of attraction.
