Force per unit length is given by:
Force on the top side of the loop:
r = 7.5 cm(1m/100cm) = 0.075 m
Length of the straight conductor, L = 30 cm(1m/100cm) = 0.30 m
i1 = 15 A
i2 = 30 A
Figure 22.57 shows a long straight wire near a rectangular current loop. What is the direction and magnitude of the total force on the loop?
