What are the properties of magnets?
Magnets have the following properties:
1. Magnets attract ferromagnetic materials, such as iron, nickel, and cobalt.
2. All magnets have two poles: north pole and south pole. There are no magnets containing only one pole.
3. Like poles of two magnets repel each other; opposite poles of two magnets attract each other.
4. The magnetic force of a magnet is stronger at its poles than in the middle.
5. The stronger the magnets and the closer two magnets are to each other, the greater the magnetic force exerted on each other.
6. When a bar magnet is suspended by a thread freely in horizontal position, its north pole will move towards the North Pole of the earth and its south pole will move towards the South Pole of the earth. This is because the earth is a giant magnet, and its geographical north pole is its magnetic south pole, and vice versa.
7. There are two types of magnets: permanent magnets and temporary magnets. Permanent magnets remain magnetized even without the influence of external magnetic field, such as a horseshoe magnet. Temporary magnets may lose their magnetism when removed from the external magnetic field, such as an iron pin.
