Class 12th Physics 2017 Set1 Delhi Board Paper Solution
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.
No, there will not be an induced emf occur in the loop as magnetic flux doesn't change linked with the circular loop because magnetic field lines are parallel to the plane of the loop.
Hence, a change in current of wire will not create any emf in the loop.
