A rectangular coil of wire has dimensions of 3 cm by 6 cm and is wound with 60 turns of wire. It is turned between the pole faces of a horseshoe magnet that produces an approximately uniform field of 0.4 T, so that sometimes the plane of the coil is perpendicular to the field and sometimes it is parallel to the field.
a. What is the area bounded by the rectangular coil?
b. What is the maximum value of the total magnetic flux that passes through the coil as it is turned?
c. What is the minimum value of the total flux through the coil as it turns?
d. If the coil makes one complete turn each second and turns at a uniform rate, what is the time involved in changing the flux from the maximum value to the minimum value?
