What are the Types of Magnets?

Magnets are among the amazing objects of nature, which have some special features. They are objects that create or create a magnetic field that can attract or repel certain types of materials containing iron and nickel. Because of these special features, magnets are used for various industrial purposes.
Magnets are made of different elements. In other words, not all magnets are made from the same elements. Based on the composition and magnetism properties, magnets can be broken down and categorized into three different types. Permanent magnets, temporary magnets, and electromagnets are the three main types of magnets available. Each species has its own special features.

Permanent Magnet

Permanent magnets are magnet types that can retain their magnetic properties after magnetization. Basically, there are four main types of permanent magnets.
Neodymium Iron Boron (NdFeB):
This type of magnet is known to have a very high coercive force and consists of rare earth magnetic material. Even the product range of the magnet is extremely high up to 50 MGOe.
Samarium Cobalt (SmCo):
This is the type of magnet that is very difficult to demagnetize as mentioned above. This is a very strong magnet with high resistance to temperature and oxidation.
Alnico:
The name Alnico is derived from the first two letters of each of the three main elements it contains, and unlike the other two types of magnets mentioned above, this magnet can easily be demagnetized.
Ceramic or Ferrite:
This type of magnet mainly consists of sintered iron oxide and strontium carbonate or barium. They are mostly inexpensive and therefore can be easily produced by pressing or sintering.

Temporary Magnets

Temporary magnets are magnets that act as permanent magnets as long as they are in the magnetic field but lose their magnetic qualities as soon as they are removed from the magnetic Temporary magnets differ greatly in their composition due to their strange nature.

Electromagnets

Electromagnets are mainly windings that act as magnets when electric current passes through them. The power of an electromagnet can be easily changed by simply changing the direction and strength of the electric current.

Magnets are basically divided into 3 main groups as mentioned above. Depending on their nature, these magnets are offered to industries by various uses. Therefore, it would not be wrong to say that magnets are one of the many useful elements we receive from nature.
