Rotating Coil

Question Text

A coil of \({{params.N }}\) turns encloses an area of \({{params.a }}\rm\ {cm^2}\). It is rotated in \({{params.t }}\textrm{ s}\) from a position where its plane is perpendicular to Earth’s magnetic field to one where its plane is parallel to the field. If the strength of the field is \({{params.B }} \times 10^{-5} \textrm{ T}\) what is the average emf induced in the coil?
