Academics

A 500-turn circular coil with an area of 0.0500 m^2 is mounted on a rotating frame, which turns at a rate of 20.0 rad/s in the presence of a 0.0500-T uniform magnetic field that is perpendicular to the axis of rotation. What is the instantaneous emf in the coil at the moment that the normal to its plane is parallel to the field?
