Current Attempt in Progress A circular coil (910 turns, radius = 0.054 m) is rotating in a uniform magnetic field. At t = 0 s, the normal to the coil is perpendicular to the magnetic field. At t = 0.029 s, the normal makes an angle of 450 with the field because the coil has made one-eighth of a revolution. An average emf of magnitude 0.078 V is induced in the coil. Find the magnitude of the magnetic field at the location of the coil.

The magnetic flux that passes through one turn of a 15-turn coil of wire changes to 2.46 from 9.07 Wb in a time of 0.0598 s. The average induced current in the coil is 277 A. What is the resistance of the wire? Number UnitsCurrent Attempt in Progress A constant magnetic field passes through a single rectangular loop whose dimensions are 0.36 m x 0.57 m. The magnetic field has a magnitude of 2.0 T and is inclined at an angle of 720 with respect to the normal to the plane of the loop. (a) If the magnetic field decreases to zero in a time of 0.46 s, what is the magnitude of the average emf induced in the loop? (b) If the magnetic field remains constant at its initial value of 2.0 T, what is the magnitude of the rate AA/ At at which the area should change so that the average emf has the same magnitude?
