A ring of radius 8.0 cm is placed concentrically around a ring of radius 6.0 cm (see figure
below). Each ring carries a current of 4.0 A.
(a) What is the magnitude of the magnetic field at the center of the rings if the two currents flow in the
same direction?
(b) Find the magnitude of the magnetic field if the currents flow in opposite directions?
(c) If the outer ring current is counterclockwise and the inner ring current is clockwise what is the
direction of the net magnetic field
