Question

A coil, with an internal resistance of 0.350-Ohms, has 25 turns and is wapped on a frame with a cross-section of 1.80 cm each side. An applied magnetic field is perpendicular to the area of the coil (straigh up). If the field changes from 0.100T to 0.500 T in 0.800-s, what is the induced emf and in what direction is the current?
