Question

The force a magnet exerts on another magnet, on iron or a similar metal, or on moving charges is

an electric force.
a magnetic force.
proportional to the charge of the magnet.
proportional to the mass of the magnet.

If the current in a wire is directed upward, what is the direction of the magnetic field produced by the current?
counterclockwise in the horizontal plane
clockwise in the horizontal plane
in the same direction as the current
in the opposite direction to the current

Answer 1

The force a magnet exerts is known as a magnetic force. The direction of the magnetic field produced by a current moving upward in a wire is counterclockwise in the horizontal plane, as determined by the right-hand rule.

Step-by-step explanation:

The force that a magnet exerts on another magnet, on iron, a similar metal, or on moving charges is known as a magnetic force. This force is not proportional to the charge or mass of the magnet since magnets do not have charge and their force is not a function of their mass. Instead, magnetic forces are caused by magnetic fields, which result from the movement of electrical charges, such as the electric current in a wire.

Regarding the direction of the magnetic field produced by a current in a wire directed upward, according to the right-hand rule (RHR-1), you point your thumb in the direction of the current and curl your fingers. Your fingers would then curl counterclockwise in the horizontal plane, indicating the direction of the magnetic field around the wire is counterclockwise.

Answer 2

Answer;

Proportional to the charge of the magnet

Explanation;

• A magnet is a substance or a material that has the capability of producing magnetic field. Magnets may repel or attract poles of another magnet. based on the basic law of magnetism, like poles of magnets repel each other while unlike poles of magnets attracts each other.
• Therefore, magnets exerts forces on each other. These forces of attraction field of magnets are as a result of currents of electrically charge electrons orbiting in the nuclei of the particles that are in the material making up the magnet. The strength of these forces is proportional to the charge of the magnet.

Answer;

counterclockwise in the horizontal plane

Explanation;

• Using the right hand grip rule, the direction of magnetic field produced by a current carrying conductor or wire can be determined.
• Right hand grip states that if one grasps the wire or the conductor using the right hand, such that the thumb points the direction of the current, then the other four fingers shows or points the direction of the magnetic field produced.
• Therefore, if the direction of the current is upward then using the right hand grip rule the direction of magnetic field will be counter clockwise on a horizontal plane.
