Question 162 of 175

A uniform magnetic field is restricted within a region of radius r. The magnetic field changes with time at a rate dBdt, Loop 1 of radius R is outside the region of magnetic field as shown in the figure. Then, the emf generated is

                  

(a) zero in loop1 and zero in loop 2

(b) -dBdtπr2 in loop 1 and-dBdtπr2 in loop 2

(c) -dBdtπr2 in loop 1 and zero in loop 2

(d) -dBdtπr2 in loop 1 and zero in loop 2
