A magnetic field is passing through a loop of wire whose area is 0.014 m2. The direction of the magnetic field is parallel to the normal to the loop, and the magnitude of the field is increasing at the rate of 0.19 T/s. (a) Determine the magnitude of the emf induced in the loop. (b) Suppose the area of the loop can be enlarged or shrunk. If the magnetic field is increasing as in part (a), at what rate (in m^2/s) should the area be changed at the instant when B = 1.4 T if the induced emf is to be zero? Use a minus sign if the area is to be shrunk. (a) Number Units (b) Number Units

An inductor with inductance L and a resistor with resistance R are wired in series to an ideal battery with emf E. A switch in the circuit is closed at time t = 0, at which time the current is zero. A long time after the switch is thrown the potential differences across the inductor and resistor are: 0, E E, 0 E/2, E/2 (L/R)E, (R/L)E unknown since the rate of change of the current is not given
