C 1 . F B t ext The magnitude of the magnetic field is increasing. F Flux: increasing due to increasing . F t loop must be down ( ) to counteract upward increasing flux; current is then clockwise. C 2 . ŒF B t ext The magnitude of the magnetic field is increasing. F Flux: increasing due to increasing . F F t loop must be up ( ) to counteract downward increasing flux; current is then counterclockwise. C 3 . B t ext The magnitude of the magnetic field is decreasing. F Flux: decreasing due to decreasing . F t loop must be up ( ) to counteract upward decreasing flux; current is then counterclockwise.
