- In the figure below, a long straight wire carries a current of 4.70 A. Find the magnitude of the net force on a rigid square loop of wire of side length l = 6.80 cm. The center of the loop is 10.10 cm from the wire and the loop carries a current of 10.0 A.À rectangular loop of wire is placed next to a straight wire, as shown in figure below. There is a current of 4.3 A in both wires. Take a = 6.0 cm, b = 11.0 cm and c = 3.0 cm. Determine %3D the magnitude and direction of the net force on the loop. (Choose toward wire direction as the positive and express the direction of the net force by using plus or minus signs in the result, which must be in multiples of 10 6 Newtons and includes 2 digit after the decimal point. That means if you get a result of a 9.22 x 10 6 and the direction of the net force is toward the wire, just type 9.22 or if you find the direction of the net force as opposite to the wire, just type -9.22 in the answer box. Maximum of 4% error accepted in your answer.
