One way to measure the strength of a magnetic field is with a flip coil. Suppose a 200 turn, 4.0 cm diameter with a resistance of 2.0 is connected to a 1.0 F capacitor. The coil is held perpendicular to the field and the capacitor is discharged. Then the coil quickly flipped 180 so that the opposite side is facing the magnetic field. Afterward, the capacitor voltage is measured to be 7.5 V. What is the field strength? Hint: Use I = dq/dt to relate the net change in change of flux to the amount of charge that flows to the capacitor.
