Two straight parallel wires are carying current I and they are r apart. What will be the force on one due to the other per unit length?

Two long and straight parallel wires are carrying current 1 A each. If the distance between the two wires be 1 m, what will be force acting per unit length on them?

If the force between the two parallel wires having carrying current, is F, then what will be the force if the current is doubled?

The distance between two long and parallel wires is b. If the current flowing through each of them is iA, what will be the force acting per unit length of each wire?

Current i_(1) and i_(2) are flowing in the same direction through tow long parallel wires kept at a distance d apart. Determine the expression for the force acting per unit length of the wires. Define 1A current from It.

A long straight wire is carrying a current. An electron starts its motion on a line parallel to the wire in a direction same as that of the current. What will be the direction of the force on the electron?

Two coaxial solenoids of different radii carry current I in the same direction . Let vecF_(1) be the magnetic force on the inner solenoid due to the outer one and veF_(2) be the magnetic force on the outer solenoid due to the inner one. Then

Two long straight parallel conducting wires, carrying equal currents, are kept 8 mm apart. To produce a force of 0.01N.m^(-1) , what should be the current?

Two long straight parallel conducts carrying steady currents I_(1) and I_(2) are separated by a distance d. Explain briefly with the help of suitable diagram, how the magnetic field due to one conductor acts on the other. Hence deduce the expression for the force acting between the two conductors. Mention the nature of this force.
