Expert Solution
Step 1
We know that we have given the the blue wire has a current I1 = 77 A, the red squar loop with the side L = 74 cm and it has a current is I2 = 79 A The distance between the side BC and blue wire is 1.7 cm.
We know tha the formula of the force is given as
------- eq 1
where is the permeability of free space
L is the side of the wire
r is the distance from the wires
