Q- An infinite wire carries current I₁ = 1.1 A in the +x direction as shown in the diagram bellow. A rectangular loop of length L = 8 cm and width w = 3 cm carries a current I₂ = 0.5 A in the clockwise direction as shown. The loop is located in the x-y plane a distance d = 3 cm from the infinite wire.

(a) What is B_top,the magnitude of the magnetic field due to the infinite wire at any point along the top segment of the loop? 

(b) What is B_bottom, the magnitude of the magnetic field due to the infinite wire at any point along the bottom segment of the loop?

(c)What is the net force acting on the loop? 

Solution:
