If the current in a current is reversed in a magnetic field, the direction of the magnetic field and the conductor will also be reversed.

What is current reversal?

The right-hand rule correctly describes this effect. The current follows the direction the thumb is pointing, but the direction of the magnetic field is dictated by the direction the finger is pointing. If the direction of the current changes, the direction of the magnetic field also changes. When the direction of the current is reversed, the compass needle moves in the opposite direction because the polarity of the magnetic field is reversed. The generated magnetic field is always perpendicular to the direction of the current and parallel to the electromagnets. Therefore, reversing the current will also reverse the direction of the magnetic field.
