Question
In the figure below, the blue wire has a current I = 77 A. The red loop is a square with sides that are 74 cm
long and it has a current of 79 A. The distance between the blue wire and wire BC is 1.7 cm. Determine the
force the blue wire exerts on wire BC and the force the blue wire exerts on wire AD.
Force of blue wire on BC =
direction of force on BC =
Force of blue wire on AD =
direction of force on AD =
D
Transcribed Image Text:In the figure below, the blue wire has a current I = 77 A. The red loop is a square with sides that are 74 cm long and it has a current of 79 A. The distance between the blue wire and wire BC is 1.7 cm. Determine the force the blue wire exerts on wire BC and the force the blue wire exerts on wire AD. Force of blue wire on BC = direction of force on BC = Force of blue wire on AD = direction of force on AD = D
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 

F = μ0I1I2L2πr ------- eq 1 

where μ0 is the permeability of free space 

L is the side of the wire 

r is  the distance from the wires
