Question

discuss about the interaction between moving charge and force between parallel currents

Answer 1

The force between two long straight and parallel conductors separated by a distance r can be found by applying what we have developed in preceding sections. the wires, their currents, the fields they create, and the subsequent forces they exert on one another. Let us consider the field produced by wire 1 and the force it exerts on wire 2 (call the force F2). The field due to I1 at a distance r is given to be
