Solution

The direction of the magnetic field around a wire is determined by the direction of the electric current. If the direction of the electric current is reversed, the direction of the magnetic field will also be reversed. This is due to the right-hand rule in physics, which states that if you point your thumb in the direction of the conventional current (from positive to negative), the direction that your fingers curl around the wire represents the direction of the magnetic field. So, if the current is reversed, the magnetic field will also reverse its direction.
