Question

In a physics laboratory experiment, a coil with 220 turns enclosing an area of 12.32cm2 is rotated in a time interval of 0.462s from a position where its plane is perpendicular to the earth's magnetic field to one where its plane is parallel to the field. The earth's magnetic field at the lab location is 89.1?T .
