Figure shows a part of an electric circuit. ABCD is a rectangular loop made of uniform wire. The length AD= BC = 1 cm. The sides AB and DC are long as compared to the other two sides. Find the magnetic force per unit length acting on the wire DC due to the wire AB if the ammeter reads 10A.

Calculate force per unit length acting on the wire B due to the current flowing in the wire A. (see figure below)

Figure shows a part of an electric circuit. The wires AB, CD, and EF are long and have identical resistances. The separation between the neighbouring wires is 1.0 cm. The wires AE and BF have negligible resistances and the ammeter reads 30 A . Calculate the magnetic force per unit length of AB and CD.

Derive an expression for the force acting per unit length of the wire in case of two long parallel wires carrying currents.

Two long and parallel wires are at a distance of 0.1m and a current of 5 A is flowing in each of these wires. The force per unit length due to these wires will be
