The diagram shows two single-turn circular loops of wire placed so they are parallel and concentric. The outer loop has radius 12 cm and carries a clockwise current I1 = 3.4 A, and the inner loop has radius 8 cm and carries a counterclockwise current I2 = 2.9 A. Calculate the net magnetic field at the center of the loops. Enter a positive answer if the net field points out of the screen toward you, and enter a negative answer if the net field points into the screen away from you.

Question

The diagram shows two single-turn circular loops of wire placed so they are parallel and concentric. The outer loop has radius 12 cm and carries a clockwise current I1 = 3.4 A, and the inner loop has radius 8 cm and carries a counterclockwise current I2 = 2.9 A. Calculate the net magnetic field at the center of the loops. Enter a positive answer if the net field points out of the screen toward you, and enter a negative answer if the net field points into the screen away from you.
(Give your answer in tesla but don't include the units.)
