A device called a flip coil can be used to measure the earth's magnetic field. The coil has 130 turns and an area of 4.5x10-2 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 6.0x10-2 mT, and the coil flips over in 0.30 s. Part A What is the average value of the emf induced in the coil during the time it is flipping?
