The polarity of a magnet does not change if the magnet is cut into pieces. Each piece has the same polarity that it had before.
In particular, if you break a bar magnet in half at the midline between the two poles, you will end up with two magnets N-S and N-S. No reversal of polarity occurs.

How does breaking a magnet change its magnetic properties?
Breaking a magnet into smaller pieces weakens its overall magnetic field, as each piece becomes a separate magnet with its own north and south poles. The smaller magnets may have different magnetic strengths and orientations compared to the original magnet.
How do you reverse the polarity of a compass that is 180 off?
Well, the easiest way to reverse the polarity of a magnet is to just turn it around. However, inside of every piece of steel, there are magnetized pieces that will make the steel an induced magnet when a magnet is placed on or by the steel. By putting the oppositely polarized magnet on or by the same steel, you may be able to reverse the magnetism of the steel. Or by making it a core of a coil in which direct current flows in such a direction as to re-polarize it
What kind of magnet can vary its strength and polarity?
An electromagnet can vary its strength and polarity by controlling the flow of electric current through its coil. By changing the direction and intensity of the electrical current, an electromagnet can easily adjust its magnetic field characteristics.
Why magnet keepers use to store magnets?

Why do nails stick at the end of the magnet and not the middle?
This is because of the polarity of the magnetic field and how north interact with south. In the middle of the magnet, the magnetic field is sort of neutral. The further away from middle and the stronger the force will be.
Will changing the polarity of the current change the polarity of the electo magnet?
Yes!
How do you use the word polarity in a sentence?
The polarity of both ends of a magnet is different. The positive and negative polarity exist for a magnet.
How can one determine the polarity of a magnet?
To determine the polarity of a magnet, you can use a compass. The end of the magnet that attracts the north pole of the compass is the magnet's north pole, and the end that attracts the south pole of the compass is the magnet's south pole.
How can the polarity of a magnet be determined?
Use a compass. It will always point to a magnet's south pole.
What type of magnet can vary its strength and polarity?
electromagnet
What kind of magnet can vary its strength polarity?
an electromagnet
What is polarity definition for kids?
opposites attracting, like a magnet.
How can you reverse the rotation of barlow's wheel?
Reverse the polarity of the magnet.
How do you identify the polarities in round magnet?
You can identify the polarities of a round magnet using a compass. The end of the magnet that points north on the compass is the north pole of the magnet, while the end that points south on the compass is the south pole of the magnet.
How to determine the polarity of a magnet without a compass?
To determine the polarity of a magnet without a compass, you can use the "hanging method." Hang the magnet from a string and observe how it aligns itself. The end that points north is the north pole, and the opposite end is the south pole.
Can you make a magnet float with another magnet of the opposite polarity?
No, opposite polarities attract, alike polarities repel.
What will happen to a spherical magnet when it enters the magnetic field of a bar magnet?
The spherical magnet will experience a force that will try to align it with the magnetic field of the bar magnet. Depending on the orientation of the spherical magnet and the bar magnet, it may either be attracted or repelled. If the polarity of the two magnets is aligned, they will be attracted to each other; if the polarity is opposite, they will be repelled.
