Question

What is the magnetic field midway between two parallel conductors carrying same
amount of current in the same direction and in the opposite direction?

Answer 1

When the magnetic field midway between two parallel conductors carrying same amount of current in the same direction and in the opposite direction, the midway between the conductors and magnetic fields are equal and the net field is zero.

When the two parallel conductors are equal and in the opposite direction, the conductors which carry the equal currents are directed as the sum of the fields.
