A bar magnet is moved rapidly toward a 45-loop coil of wire. As
the magnet moves, the magnetic flux through the coil increases
from 1.3 x 10-5 T m² to 3.7 x 103 T m² in 0.25 s. (a) What
is the magnitude of the induced emf? (b) If the resistance of the
wire in the coil is 3.6 2, what is the induced current?
