# Question about ordinary magnets. (Not homework)

• makbar59
In summary, magnets work by creating a magnetic field that attracts or repels other objects due to the alignment of atoms within the magnet. There are three main types of magnets: permanent, temporary, and superconducting. Over time, magnets can lose their magnetism through demagnetization. The north pole of a magnet is the side attracted to the Earth's north pole, and a compass can be used to determine polarity. Magnets have many practical uses in motors, generators, speakers, hard drives, and everyday items like refrigerator magnets and magnetic closures.

Is there a line splitting a magnet into north and south? What is this line called? Also does the line divide the magnet equally?

No, and no.

Do you know any websites which would explain better about how a magnet reacts to other magnetic fields between its two poles? or something like that?

## 1. How do magnets work?

Magnets work by producing a magnetic field that attracts or repels other objects. This is due to the alignment of the atoms within the magnet, creating a force that can act on other magnetic materials.

## 2. What are the different types of magnets?

The three main types of magnets are permanent magnets (such as bar magnets), temporary magnets (such as electromagnets), and superconducting magnets.

## 3. Can magnets lose their magnetism?

Yes, over time, magnets can lose their magnetism due to exposure to high temperatures, strong magnetic fields, or physical damage. This process is known as demagnetization.

## 4. How can I tell which side of a magnet is positive or negative?

The side of a magnet that is attracted to the Earth's north pole is considered the north pole of the magnet, and the opposite side is the south pole. You can also use a compass to determine the polarity of a magnet.

## 5. What are some practical uses for magnets?

Magnets have a wide range of practical uses, including in motors, generators, speakers, hard drives, and MRI machines. They are also used in everyday items such as refrigerator magnets, magnetic toys, and magnetic closures on clothing.
