Chapter 25, Problem 30MCQ
A device called a flip coil can be used to measure the earth’s magnetic field. The coil has 100 turns and an area of 0.010 m2. It is oriented with its plane perpendicular to the earth’s magnetic field, then flipped 180° so the field goes through the coil in the opposite direction. The earth’s magnetic field is 0.050 mT, and the coil flips over in 0.50 s. What is the average emf induced in the coil during the flip?
A. 0.050 mV
B. 0.10 mV
C. 0.20 mV
D. 1.0 mV
