Prove that the parallel conductors of infinite length, carry current in the same direction, attravt each other. Deduce the expressions for the force per unit length experienced by each conductor.

Two parallel wires carrying currents in the same direction attract each other because of:

WHat is the direction of force between two parallel conductors carrying current in same direction

A horizontal wire AB of length 'l' and mass 'm' carries a steady current I_1 , free to move in vertical plane is in equilibrium at a heigh of 'h' over another parallel long wire CD carrying a steady current I_2 , which is fixed in a horizontal plane as shown. Derive the expression for the force acting per unit length on the wire AB and write the condition for which wire AB is in equilibrium.

Write the expression for the magnitude of force per unit length between two infinitely long parallel straight conductors.

A currentof 5.0 A is flowing in eah of the two parallel conductors of infinite length separated by certain distance apart in vacuum in the same directions. Each conductor expereinces a force of 2xx10^-4N m^-1 due to the other. Find the separation between the two conductors.
