A long straight current carrying wire...

A long straight current carrying wire passes normally through the centre of circular loop. If the current through the wire increases, will there be an induced emf in the loop ? Justify.

Text Solution

Verified by Experts

No, there will no induced emf, as mag. Flux `(phi)` does not change from relation `phi = BAcos theta, theta = 90^(@)`, Flux linked with the loop `phi = BA cos 90^(@) = 0`.
