A rectangular coil with resistance R has N turns, each of length, and width w. The coil moves into a uniform magnetic field B Sin with constant velocity v. What are the magnitude and direction of the total magnetic force on the coil (a) as it enters the magnetic field, (b) as it moves within the field, and (c) as it leaves the field?

Transcranial magnetic stimulation (TMS) is a noninvasive technique used to stimulate regions of the human brain. A small coil is placed on the scalp, and a brief burst of current in the coil produces a rapidly changing magnetic field in the brain. The induced emf can be sufficient to stimulate neuronal activity. One such device generates a magnetic field within the brain that rises from zero to 1.5T in 120msec. Determine the induced emf within a circle of tissue of radium 1.6mm that is perpendicular to the direction of the field.
