Suppose the radius r of a circular loop increases linearly with time as r = vt, where v is the radial velocity of a point on the loop. There is a uniform magnetic field B perpendicular to the plane of the loop. IfB varies with time as B(t)-B (1+2)7. The magnitude of the induced c.m.f. in the coil at r = 2 sec is 28 B,vt 28-B1 16: By Zero (a) (b) (d (d) Solution Suppose the radius r of a circular loop increases linearly with time as r = vt, where v is the radial velocity of a point on the loop.
