Unformatted text preview: induced emf be when the coil leaves the magnetic field? A. Clockwise B. Counter-clockwise C. Need to know direction in which the coil is moving to answer D. Need to know the speed of the coil to answer E. No way to tell _B _ 3. A coil of wire having N turns, each of cross-sectional area A , is initially in a magnetic field of strength B , with the axis of the coil parallel to the magnetic field lines. The coil is then removed from the magnetic field and brought to a region where there is no magnetic field. What is the magnitude of E dt for this procedure, where E is the emf induced in the coil when it is removed from the field? A. dt d B D. zero B. NBA E. It cannot be determined from the information given. C. 2 NBA...
