If you break a bar magnet in half, each half

If you break a bar magnet in half, each half becomes a magnet.

Explanation:

A substance which attracts or repels another similar substance is known as magnet. When domains align in single direction in a substance, it acts as a magnet. A magnet has two poles- North pole and South pole. Like poles repel each other and unlike poles attract each other. Mono-poles do not exist. So, when a magnet is broken into two halves, each half forms another magnet with two poles.

If you break a bar magnet in half, each half will have a new south pole, a north pole and a neutral zone.  In other words, two new magnets will be generated.

Explanation:

A magnet is a body of any material capable of producing a magnetic field and attracting itself or being attracted to another magnet or to any other body of iron, cobalt or other ferromagnetic metals (ferromagnetism is a physical phenomenon in which magnetic ordering occurs of all the magnetic moments of a sample, in the same direction and direction. In other words, the ferromagnetic interaction is the magnetic interaction that makes the magnetic moments tend to be arranged in the same direction and direction. This property makes the ferromagnetic materials they are intensely magnetized when they are placed in a magnetic field, and retain part of their magnetization when said field disappears.). Then the magnet is a material with natural or artificial ferromagnetic properties, which generate a continuous magnetic field.

Magnets are magnetically charged bodies, which generate a magnetic field around them oriented according to two poles: negative pole (also called South pole) and positive pole (also called North pole). Opposites attract each other (positive-negative) and equal poles repel each other (positive-positive or negative-negative). The line that joins both poles is called the magnetic axis. This line located in the central zone located between both poles has no attraction or repulsion capacity.

In the event that a magnet is broken into pieces, each new fragment will have a new south pole, a north pole and a neutral zone. That is, equal and opposite poles appear on each side of the breaking point. This happens even if the fragments are of different size.
