A magnetic field passes through a stationary wire loop, and its magnitude changes in time according to the graph in the drawing. The direction of the field remains constant, however. There are three equal time intervals indicated in the graph: 0 - 3.0 s, 3.0 - 6.0 s, and 6.0 - 9.0 s. The loop consists of 43 turns of wire and has an area of 0.13 m2. The magnetic field is oriented...

(a) If the area A = 0.012[m) is constant, but the magnetic field is increasing at the rate of 0.020 T/s), determine the induced emf. (Use Faraday's law; the induced emf in a loop equals the absolute value of the time rate of change of the magnetic flux through the loop.) (b) If the total resistance of the circuit is 5.0(82), find the induced current. (c) Suppose we change the...
