Question

what happens to the direction of the magnetic field if the direction of current through the straight conductor is reversed ?​

Answer 1

Explanation:

The magnetic field lines lie in a plane perpendicular to the wire. If the direction of the current is reversed, the direction of the magnetic field reverses. The strength of the field is directly proportional to the magnitude of the current.

Answer 2

Answer: the direction of magnetic field lines get reversed if the direction of current through the straight copper wire is reversed.
