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? O 0.59 m V mv 1.2 mV 0 2.3 m V O 12 mV
A scalloped hammerhead shark swims at a steady speed of 1.4 m/s with its 82-cm-wide head perpendicular to the earth's 57 uT magnetic field. Part A What is the magnitude of the emf induced between the two sides of the shark's head? Express your answer in millivolts. VO O AED ? E =
