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?
There is no reversal of polarity when a magnet is broken. If you break a magnet, labeled N--S, into two, then you end up with two magnets of N--S and N--S.
What kind of magnet can vary its strength and polarity?
Electromagnet
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
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.
What is the use of a magnet in a motor?
Magnets are used in motors to create motion. Magnets have two kinds of polarity, positive (north) and negative (south). When two magnets of the same polarity are facing each other, they will be attracted to each other. Conversely, if the polarity of the the two magnets are opposites than they two magnets will be repulsed. This concept of rotational motion is what is occurring in a motor.
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 do you identify the polarities in round magnet?
You can identify the polarities in a round magnet by placing another magnet next to it. If they repel they have the same polarity and if they are attracted the polarity is the same.
How does breaking a magnet change its magnetic properties?
There is no reversal of polarity when a magnet is broken. If you break a magnet, labeled N--S, into two, then you end up with two magnets of N--S and N--S.
Which side on a magnet is the weakest?
The poles of a magnet are of equal strength but opposite polarity.
How can the polarity of a magnet be determined?
Use a compass. It will always point to a magnet's south pole.
What kind of magnet can vary its strength and polarity?
Electromagnet
What kind of magnet can vary its strength polarity?
an electromagnet
What type of magnet can vary its strength and polarity?
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.
Why magnetic objects attracts to only one side of a magnet?
They are the opposite polarity to the side of the magnet they are attracted to.
