The magnetic field between the poles of the electromagnet in Fig. is uniform at any time, but its magnitude is increasing at the rate of 0.020 T/s. The area of the conducting loop in the field is 120 cm2, and the total circuit resistance, including the meter, is 5.0 2. (a) Find the induced emf and the induced current in the circuit. (b) If the loop is replaced by one made of an insulator, what effect does this have on the induced emf and induced current?
