Physics

The loop is in a magnetic field 0.22 T whose direction isperpendicular to the plane of the loop. At t = 0, the loophas area A = 0.285 m2.Suppose the radius of the elasticloop increases at a constant rate,dr/dt = 3.45 cm/s .

A)

Determine the emf induced in the loop at t = 0 and att = 1.00 s .
