What happens to the magnecticfield when the current through the solenoid is reversed?

When the current through a solenoid is reversed, the direction of the magnetic field generated by the solenoid also reverses. This occurs because the magnetic field is directly related to the direction of the current flow according to the right-hand rule. The north and south poles of the magnetic field switch places, effectively altering the orientation of the magnetic field lines surrounding the solenoid.
