A rectangular coil of wire has a dimensions of 1.6 cm by 9.6 cm and is wound with 59 turns of wire. It is turned between the pole faces of a horseshoe magnet that produces an approximately uniform field of 0.28T, so that sometimes the plane of the coil is perpendicular to the field and sometimes it is parallel to the field.
Q: If the coil makes on complete turn each 1.8s and turns at a uniform rate, what is the time involved in changing the flux from the maximum value to the minimum value?
