In the same plane, there are three parallel long straight wires with equal distance. 1, 2 and 3 have the same current of 1, 1 and 1 ampere respectively. Their forces are F1, F2 and F3 respectively

In the same plane, there are three parallel long straight wires with equal distance. 1, 2 and 3 have the same current of 1, 1 and 1 ampere respectively. Their forces are F1, F2 and F3 respectively

The forces on them are F1, F2 and F3
Then F1: F2: F3 = 1:0:1
