A constant magnetic field passes through a single rectangular loop whose dimensions are 0.33 m x 0.50 m. The magnetic field has a magnitude of 2.3 T and is inclined at an angle of 70 degrees with respect to the normal to the plane of the loop. (a) If the magnetic field decreases to zero in a time of 0.44 s, what is the magnitude of the average emf induced in the loop? (b) If the magnetic field remains constant at its initial value of a 2.3 T, what is the magnitude of the rate change in A/ change in t at which the area should change so that the average emf has the same magnitude?
