Question

A rectangular coil of length 0.5 m and
breadth 0.4 m has resistance of 5 . The coil is
placed in a magnetic induction of 0.05 T and
its direction is perpendicular to the plane of
the coil. If the magnetic induction is
uniformly reduced to zero in 5 mili seconds,
find the e.m.f. and current induced in the coil.

Answer both, thanks
The magnetic field at a distance r=50 cm away from the wire is 6.8 x 10(-7) T. Compute the wire's current.
