it exerts an electric force.

it exerts a magnetic force.

it exerts a polar force.

it exerts a force proportional to the magnet’s charge.

How does a magnet affect another magnet, something made of iron or a similar metal, and moving charges?

It exerts a magnetic force.

~Hope this answers your question!~

The correct answer is "it exerts a magnetic force".

Explanation:

Magnet: It has magnetic properties. It has two poles: south pole and north pole.

Magnets attract the iron or other metal. It is due to the influence of their magnetic field. The atoms of the iron gets align their electrons. In this way, the iron gets magnetized.

There is a magnetic force of attraction between the opposite poles. There is a magnetic force of repulsion between the same poles.

The current carrying conductor produces the magnetic field around it.

If the compass needle is placed near the current carrying conductor then it will show the deflection. It shows the presence of the magnetic field around the current carrying conductor. It exerts a magnetic force.

Therefore, the option "It exerts a magnetic force" is a correct.
