Uses of magnets

A magnet is a piece of iron material that has magnetism properties. Magnetic is in the category of the tools that humans come into contact with directly or indirectly, often in a typical day. Magnetic material varies in shape and size, and this increases their applications. This article will examine most of the areas and fields that use magnets.

The Neodymium Magnet, also referred to as NdFeB, NIB, or Neo Magnet, is the most commonly utilized variety of Rare Earth Magnet. This permanent magnet is crafted from a blend of neodymium, iron, and boron, which together form a tetragonal crystalline structure known as Nd2Fe14B.

1. Making Compasses

Magnet material has a powerful role in the production of compasses. The magnet is attached to the compass to ensure the poles are aligned. That is, to ensure the needle or the arrow of the compass is pointing north.

2. Food industry

A magnet is a crucial tool in the processing and sorting of foods. It is used to separate food materials from magnetic materials. It is one of the simplest ways of cleaning foods before they are processed and packed.

3. Generators

Generators primarily rely on magnets in their application. Generators have a strong magnet installed inside them, and the magnet determines the amount of electricity to be produced. When used in generators, the magnet converts the mechanical energy of the generator to electrical energy. Therefore, the larger the magnet installed in the generator, the higher the electrical energy produced.

4. Collecting Metallic materials

Handpicking metallic material may be tedious and may cause harm to your fingers. Thankfully, the use of magnets has eased the process of collecting scattered metallic materials. Nails, for example, can be collected by hovering the magnet where they are scattered.

5. Televisions

All types of televisions have a magnet installed inside them. The magnet causes the electromagnets responsible for transmitting energy from one part of the television to another. In addition, the television speaker is made up of a magnet that helps in the conversion of electrical energy to sound energy.

6. Electric Bell

If you have been to modern institutions, you may have seen electric bells. Electric bells work under the principle of magnetism. When the electric current is allowed to pass to the bell, the electromagnetic current is powered, creating magnetic fields in the bell. The striker is attracted to the bell and strikes the bell’s gong to produce the sound.

7. Holding pins

They say prevention is better than cure, and thus to concur with their words; we need to place pins in a secure place. Sharps pins expose human beings to disasters and dangers; therefore, we need to place them in an enclosed disk or container. However, if you do not have an extra dish to keep your pins, magnets got you covered. Pins are magnetic materials, and thus they are attracted to the magnet.

8. Holding sewing pins

While sewing, you need to handle the sewing pin with care to avoid any related dangers. Sometimes, you may need to pause the sewing process and leave the pins attached to the clothes. These practices are risky and may expose the user to dangers. However, using a magnet to attach the sewing pins can help promote the user’s safety.

9. Radio production

Radio and speaker industries directly depend on magnets. The speakers found in radios and other components are made with magnetic material. The magnetic material in these speakers helps convert electrical energy to sound energy. In addition, magnets are used in these industries to hold metallic tools used in the assembling process.

10. Hospitals

Magnetic Resonance Imaging procedures widely use the magnetism principles. The procedure involves using a magnet with powerful fields that allow the doctor to view internal parts of the body.

11. Making of fridges

Fridges and freezers are good examples of magnetic products. Their doors are sealed with a magnetic mechanism that allows users to open the door easily. In addition, the magnetic field at the door helps in attaching pictures and other metallic materials.

12. Home appliances

Most home appliances and tools are made from magnetic materials. When used in these appliances, the electromagnetism principle is used to perform various tasks. Some appliances that use the principle of electromagnetism include an electric fan, an electric doorbell, an induction cooker, and magnetic locks.

13. Storage devices

Most storage devices work on the principle of electromagnetism. The magnetic disk, for example, uses magnetization and the electromagnetism principle to store, access, and write data to the memory. This type of memory contains magnetic material as the coating. Therefore, when working with such storage devices, avoiding too much contact with metallic materials is advisable.

14. Making of toys

Magnetic has numerous applications in the manufacturing of toys and other dummy products. A toy building block, for example, has its blocks attached to a magnet. Other toy products, like the train, have segments attached to each other using magnets.

15. Jewelry

Magnet has numerous applications in the jewelry industry. In the production phase, magnets hold tools and parts of the jewelry. Then, in the case of necklaces, the ends have magnetic clips that allow them to clip around your neck.

16. Used in Cranes

If you have been to an offloading point, you may have seen how the cranes work. One of the ends of the crane has a strong magnet attached to it. The magnet allows the crane to hold the container as they are being lifted firmly.

17. used for filtration

In the industry, magnets play a vital role in removing unwanted metallic materials. Magnets are the easiest way to attract and separate metallic and non-metallic materials.

18. Hanging arts

Some of the arts rely on the magnetism principle. In some modern art, you do not need to have a hole in the art to hang it on the wall. These arts are equipped with a magnetic clip that helps them to hang on the wall.

19. Train and Electric cars

Trains hover above the magnetic railway line that generates magnetic fields which push the train forward. In addition, electric and hybrid cars use magnetic, which promotes locomotion.
