The plane of a square loop of wire with edge length a = 0.200 m is oriented vertically and along an east–west axis. The Earth’s magnetic field at this point is of magnitude B = 35.0 μT and is directed northward at 35.0° below the horizontal. The total resistance of the loop and the wires connecting it to a sensitive ammeter is 0.500 Ω. If the loop is suddenly collapsed by horizontal forces as shown in Figure P30.37, what total charge enters one terminal of the ammeter?
