Question

A coil formed by wrapping 80 turns of wire in the shape of a
square is positioned in a magnetic field so that the normal to the plane of
the coil makes an angle of 60.0
∘ with the direction of the field. When the
magnetic field is increased uniformly from 100 mT to 500 mT in 0.20 s,
the emf of magnitude 50.0 mV is induced in the coil. What is the total
length of the wire in the coil?
