A rectangular loop of area A is placed in a region where themagnetic fieldis perpendicular to the plane of the loop. The field is allowed tovary its magnitude with time,according to the expression B = Bmax e^−t/τ where both Bmax and τare constant. The field has tot < 0 a constant value Bmax. Use Faraday's law to show that theinduced emf in thespire is given by:
