Question:

A rectangular loop of wire, carrying current I1 = 2.0 mA, is next to a very long wire carrying a current I2 = 8.0 A.
(a) What is the direction of the magnetic force on each of the four sides of the rectangle due to the long wire's magnetic field?
(b) Calculate the net magnetic force on the rectangular loop due to the long wire's magnetic field.
