All the magnets have two types of poles: north-seeking poles or north poles and south-seeking poles or south poles.
The magnetic strength is the strongest at the poles of the magnet.
When you freely suspend a bar magnet in a horizontal position, the magnetic field of the bar magnet will interact with the magnetic field of the Earth. This will cause the bar magnet to come to rest in a north-south direction, where the north pole of the magnet points to the north pole of the Earth.
Like poles repel and unlike poles attract. (just as like charges repel and unlike charges attract).
Magnets attract magnetic materials such as iron, steel, cobalt and nickel.
The stronger a magnet, the larger will be the attractive or repulsive force between other magnets.
The closer together the two magnets are, the greater is the magnetic force between them.
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.
