A circular coil enclosing an area of 160 cm² is arranged horizontally. The coil has 210 turns of copper wire. The wire making up the coil has resistance of 3.00 2, and the ends of the wire are connected to form a closed circuit. Initially, a 2.00-mT uniform magnetic field points perpendicularly upward through the plane of the coil. The direction of the field then reverses so that the final magnetic field has a magnitude of 3.10-mT and points downward through the coil. If the time required for the field to reverse directions is 0.750 s, determine the magnitude of the average current in the coil during that time.

During a transcranial magnetic stimulation (TMS) treatment, a magnetic field, typically of magnitude 5.00 T, is produced in the brain using external coils. During the treatment, the current in the coils (and hence the magnetic field in the brain) rises from zero to its peak in about 75.0 μs. Assume that the magnetic field is uniform over a circular area of diameter 2.00 x 10-2 m inside the brain. What is the magnitude [E] of the average induced emf around this region of the brain during the treatment? |ε| =
