Magnet and Its Applications
As the world is advancing towards a new technological era, more and more new inventions are being made. Even though all inventions are considered in one way or another, the invention of magnet is considered the greatest achievement of mankind. Magnet has made transportation and power and energy generation a much easier and effective process.
What is a magnet?
A magnet is basically a material or an object that creates a magnetic field around itself and attracts ferromagnetic materials like iron and attracts or repels other magnets. The earliest existence of magnets was around 2500 years ago in India, China and Greece. By the 12th and 13th centuries, magnets were being used extensively in several Asian and European countries in the form of magnetic compasses.
Magnets are available in several shapes and sizes and are used for home as well as industrial uses. The two major varieties of magnets are electromagnets and permanent magnets. Electromagnets generally consist of a coil wire that behaves as a magnet when an electric current passes through it. Permanent magnet on the other hand, is created from a magnetic material that is having a persistent magnetic field.
Magnets have gained immense popularity and is nowadays used in a host of application areas. All the major activities, whether industrial or otherwise, are undertaken with the use of magnets and due to high dependency on the use of magnets, their absence will be conspicuous. It would be quite right to say that magnets are crucial for the subsistence of the contemporary world.
Magnets are used for a variety of purposes and have various applications.
- Magnets are used extensively in floppy disks, cassettes and hard disks. Magnets, due to their property of attracting a multitude of things, are produced in the form of thin coating films on which data is stored or recorded.
- Magnets serve a variety of industrial purposes. They are used in industrial equipment like separators, sweepers, pullers, conveyors and welding devices besides others.
- Magnets are also used widely in magnetic therapy devices that include magnetic waist belts, magnetic massager, knee magnets and magnetic mattresses, etc.
- Credit, Debit and ATM cards have magnetic strips on one side that encodes the information about the individual and his account and bank details.
- The use of magnets is also common in speaker and microphones.
- Electronics motors and generators also work with the use of magnets.
- Another extensive use of magnets is in the health sector. Hospitals use Magnetic Resonance Techniques (MRI) to scan various organs in the human body and for surgical purposes.
- Household equipment like headphones, telephones, television, refrigerators, water pumps, etc. also make use of magnets.
- Magnets are also used in a variety of jewelry items like bracelets, earrings, pendants and necklaces.
- Other uses of magnets include uses in tools, toys, science projects, vinyl magnet sheets, compasses, fail-safe devices, etc.
