Do all magnets have 2 poles? Do you want to know the answer to this question, today Courage Magnets Xiaofei for you to briefly introduce this question and answer why can not be a single(one) pole?

Yes, all magnets have two poles - a north pole and a south pole. This is a fundamental property of magnets.

Magnetic poles and attraction and repulsion of bar magnets

The 2 poles arise from the aligned dipole moments of the atoms/molecules that make up the magnetic material. The north and south poles represent the regions where magnetic field lines arise from and re-enter the magnet.

Even if the magnet is cut into multiple pieces, each magnet will have a north pole at one end and a south pole at the other. The magnetic field lines would rearrange themselves to form a closed loop from north pole to south pole in each magnet.

It is also impossible to separate a magnetic pole by cutting the magnet. The two magnetic poles are inseparable and are always present at the same time in any magnetic object.

Some customers of motors, sensors, encoders will need magnets with more than 2 pole, such as 4 poles, 6 poles, 8 poles, 10 poles, 14 poles, 16 poles, 24 poles, etc., but there are always North and South poles, NSNS are arranged in this way.

In summary: Whether the magnets are normal magnetized, or single or double sided multi-pole magnetized, they will have north and south poles, and the poles will always appear in pairs.
