A coil is wrapped with 233 turns of wire on the
perimeter of a square frame of sides 18.8 cm.
Each turn has the same area, equal to that of
the frame, and the total resistance of the coil
is 3.65
. A uniform magnetic field is turned
on perpendicular to the plane of the coil.
If the field changes linearly from 0 to
0.228 Wb/m2 in a time of 0.992 s, find the
magnitude of the induced emf in the coil while
the field is changing.
