Question
A long, straight wire carries 20 A. A 5.0-cm by 10-cm rectangular wire loop carrying 500 mA is located 2.0 cm from the wire, as shown in the figure (Figure 1) Part A Find the magnitude of the net magnetic force on the loop. F = 2.8 10^-3 Part B Find the direction of the net magnetic force on the loop. The net magnetic force on the loop is directed to the right The net magnetic force on the loop is directed to the left. The net magnetic force on the loop is directed into the page. The net magnetic force on the loop is directed out of the page.Explanation / Answer
F = [mu * I1 * I2 * l / 2 pi] * [1/2cm - 1/7cm]
= (2 * 10-7 ) (20) (1/2 A) (10 cm) (5 / 14 cm)
= 7.14 * 10-6 N
