Question

What is the force required by the current carrying wire passing through the same direction in the magnetic field?

Answer 1

Force is zero because current flow in the direction of length.so length is also parallel to magnetic field.
F=i(l×B).

Answer 2

The magnetic field exerts a force on acurrent-carrying wire in a directiongiven by the right hand rule 1 (thesame direction as that on the individual moving charges).
