Exercise 62

A circular loop of radius 12.0 cm is placed in a uniform magnetic field. (a) If the field is directed perpendicular to the plane of the loop and the magnetic flux through the loop is 8.00 × 10 3 T · m 2 , what is the strength of the magnetic field (b) If the magnetic field is directed parallel to the plane of the loop, what is the magnetic flux through the loop
