Problem: a. What is the magnitude of the net force on the first wire in (Figure 1)?b. What is the magnitude of the net force on the second wire in (Figure 1)?c. What is the magnitude of the net force on the third wire in (Figure 1)?

FREE Expert Solution

The magnitude of magnetic force between parallel current-carrying wires is:

F=μ0i1i2l2πr

a.

F1 = F12 - F13

F1=μ0i1i2l2πr1-μ0i1i3l2πr2=(4π×10-7)(10)(10)(50×10-2)2π(2.0×10-2)-(4π×10-7)(10)(10)(50×10-2)2π(4.0×10-2)
