Question

A closely wound rectangular coil of 80 turns has dimensions of 25.0 cm by 40.0 cm. The plane of the coil is rotated from a position where it makes an angle of 43.0 ∘ with a magnetic field of 1.70 T to a position perpendicular to the field. The rotation takes 0.0700 s .

What is the average emf induced in the coil?
