Question:
Experiments to study vision often need to track the movements of a subject??s eye. One way of doing so is to have the subject sit in a magnetic field while wearing special contact lenses with a coil of very fine wire circling the edge. A current is induced in the coil each time the subject rotates his eye. Consider the experiment of FIGURE P30.60 in which a 20-turn, 6.0-mm-diameter coil of wire circles the subject??s cornea while a 1.0 T magnetic field is directed as shown. The subject begins by looking straight ahead.What emf is induced in the coil if the subject shifts his gaze by 5? in 0.20 s?
