Chapter 27, Problem 53P
A flip coil is used to measure magnetic fields. It’s a small coil placed with its plane perpendicular to a magnetic field, and then flipped through 180°. The coil is connected to an instrument that measures the total charge Q that flows during this process. If the coil has N turns, area A, and resistance R, show that the field strength is B = QR/2NA.
