Solving a problem in physics section 61 point 47 electr

47. The circuit of wire bent into a square shape with sides a = 0,5 m, is located in one plane with an infinite straight wire carrying a current I = current 5A that two of its sides parallel to the wire. The current in the circuit I1 = 1 A. Determine the force acting on the loop if the nearest to the wire circuit side is at a distance b = 10 cm. The directions of the currents are indicated in the figure.
