The plane of a rectangular coil, (7.8 , textcm) by (3.4 , textcm), is perpendicular to the direction of a uniform magnetic field (B). If the coil has (63) turns and a total resistance of (5.4 , Ω), at what rate must the...
a) magnetic field change to induce an emf of (3.6 , textV).
b) coil move to induce an emf of (6.9 , textV).
c) current change to induce an emf of (7.2 , textV).
d) magnetic flux change to induce an emf of (8.1 , textV).
