Question

10. Two conductors are kept parallel to each other separated by a small gap. D.C current is passed in them
such that the current in both the conducts are in the same direction, then
(a) the conductors attracts one another
(b) the conductors repels from each other
(c) issues of attraction and repulsion does not arise.
(d) they develop only magnetic field around themselves.

(Kindly provide reasons)​

Answer 1

There are equal positive and negative charges in each wire thus the net force is zero. If there are parallel currents moving to the right then we can assume that either the positive charges are moving to the right or the negative charges are move to the left or even both charge polarities are in motion.

Answer 2

Answer:

yes the conductor attract one other because one side is positive or another side is negative
