Question

The radius of the circular loop is ′a′. Magnetic field is increasing at the constant rate α Magnetic field is confined to a cylindrical region and axis of magnetic field coincides with the axis of the loop. Resistance per unit length of the wire of loop is ρ. Choose the CORRECT option(s) :-
           

Options

A.Current in the loop PQRS is anticlockwise
B.Current in the loop PQRS in clockwise
C.Current in the wire PR is zero
D.Current in the wire PR is

Solution

Induced emf = A
or e = πa2α
IPQRS =
IPR = 0
