In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.
When the direction of the current in a wire is reversed in a magnetic field, the direction of the force acting on the wire also reverses. This causes the wire to move in the opposite direction within the magnetic field.
The direction of the magnetic field around the electric current also reverses when the direction of the current is reversed. This is determined by the right-hand rule, where the direction of the magnetic field is perpendicular to the direction of the current flow.
When the electric current is reversed on an electromagnet, the direction of the magnetic field is also reversed. This means that the north and south poles of the electromagnet switch places. This change in polarity can have various effects depending on the application, such as reversing the direction of motion in a motor or changing the direction of attraction or repulsion in a magnetic system.
When a current-carrying wire is placed in a magnetic field, a force is exerted on the wire due to the interaction between the magnetic field and the electric current. This force causes the wire to move or experience a deflection, depending on the orientation of the wire and the magnetic field.
When a compass is held close to a wire carrying a current, the magnetic field produced by the current will deflect the compass needle. This happens because a magnetic field is generated around the wire due to the flow of current, and the compass needle aligns itself with this magnetic field. The deflection of the compass needle can be used to determine the direction of the current in the wire.

When a compass is held close to a wire carrying current, the magnetic field created by the current induces a magnetic field around the wire. The compass aligns with this magnetic field and its needle will deflect in a direction perpendicular to the wire. This can be used to determine the direction of the current flow in the wire.
The iron filings will align themselves along the magnetic field lines produced by the current, forming a visible pattern on the cardboard. This demonstrates the presence of a magnetic field around the current-carrying wire.
The needle of a compass will deflect from its original position when a wire carrying an electric current is placed across it. This is due to the magnetic field created by the current in the wire, which interacts with the magnetic field of the compass needle, causing it to move.
When a compass is brought near a current-carrying wire, the magnetic needle of the compass will align itself perpendicular to the wire due to the magnetic field created by the flowing current. This effect is known as the right-hand rule for electromagnetism.
When a compass is placed near a current-carrying conductor, the magnetic field produced by the current can interact with the compass needle, causing it to deflect from its original position. This phenomenon is known as the magnetic field produced by the current affecting the magnetic needle in the compass. The direction of the deflection will depend on the orientation of the current and the compass in relation to each other.
When the current through the conductor is reversed, the magnetic field around the conductor will also reverse. As a result, the compass needle in Figure 7-11 will deflect in the opposite direction compared to when the current was flowing in the original direction.
