Which of the following is NOT a factor in determining the torque on a loop of wire? A. the current in the wire B. the area of the loop C. the shape of the loop D. the angle the loop makes with the magnetic field
Foroday's Low Cornea 6.0-mm-diameter coil 4. 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 whille 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 shown in which a 20-turn, 6.0-mm-diameter coil of wire circles the subject's cornea while a 1.0T magnetic field is directed as shown. The subject begins by Eye looking straight ahead. What emf voltage is induced in the coil if the subject shifts his gaze by 5'5* in 0.20s?
2. Suppose that a rectangular toroid has 2000 windings, h = 1 cm, an inner radius of R1 = 4 cm, and an outer radius of R2 = 6 cm. What is the current flowing through the toroid when the energy in its magnetic field is 2.0 x 10-6 J?
