A flat coil of copper wire consists of 100 loops and has a total resistance of . The coil diameter is 4.00 cm and it is in a uniform magnetic field pointing toward you (out the page). The coil orientation is in the plane of the page. It is then pulled to the right (without rotating) until it is completely out of the field.
(a) What is the direction of the induced current in the coil: (1) clockwise, (2) counter-clockwise, or (3) there is no induced current?
(b) During the time the coil leaves the field, an average induced current of 20.0 mA is measured. What is the average induced emf in the coil?
(c) If the field strength is 5.50 mT, how much time did it take to pull the coil out?
