Two long, thin wires distant a apart exert a force F on one another when current through each wire is i. The distance between the wires is doubled and the current is decreased to `i// 3`. The force they exert on one another now-

If the distance between two parallel current carrying wire is doubled. What is the force between them?

Does one part of a wire carrying curent exert a force on another part of the same wire?

If the distance between two parallel current carrying wires is doubled, what is the force between them?

Two long parallel wires, separated by a distance R have equal current I flowing in each of them. The magnetic field of one exerts a force F on the other. The distance R is increased to 2R and the current in each wire is reduced from I to I//2 . What is the force between them now?

Two long parallel wires, separated by a distance R have equal current I flowing in each of them. The magnetic field of one exerts a force F on the other. The distance R is increased to 2R and the current in each wire is reduced from I to I//2 . What is the force between them now?

Two long parallel wires carrying equal current separated by 1m , exert a force of 2xx10^(-7)N//m on one another. The current flowing through them is

Two long conductors, separated by a distance d carry current I_(1) and I_(2) in the same direction . They exert a force F on each other. Now the current in one of them is increased to two times and its direction is reversed . The distance is also increased to 3d. The new value of the force between them is
