It is desired to use a magnetic field of 2.00 × 10-4 teslas to produce a total magnetic flux of 6.28 x 10-8 webers through a circular loop of wire. How should the loop be oriented rela- ive to the field if we want to achieve this with the smallest loop possible? (Draw a picture to express your answer.) What will be the radius of the wire loop required?
