A device called a flip coil can be used to measure the earth's magnetic field. The coil has 160 turns and an area of 2.0×10−2 m2m2 . 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 9.0×10−2 mTmT , and the coil flips over in 0.40 ss . What is the average value of the emf induced in the coil during the time it is flipping? A) 0.36 mVmV B) 0.72 mVmV C) 1.4 mVmV D) 7.2 mVmV
