People rely on magnets for industrial and commercial use. Since scientists began creating very strong magnets using electricity, magnets have become essential to the medical and electronic sectors. People even rely heavily on magnets in their homes. Briefly discuss three uses of magnets in different fields.

(i) Computes and Electronics. Every computer contains magnets for data storage on hard drives and to display images on computer screens. In electronics, the magnets guide electrons and metals to the appropriate place.
(ii) Industry. Electric generators rely on magnets to convert mechanical energy into electricity, while some motors work in reverse. Electromagnetic cranes grab and move large amounts of metal. The maglev (magnetic leviation) trains operate using two opposing magnets that cause the train to float, making it extremely maneuverable and fast.
(iii) Health and Medicine. Magnets are used in X-rays and MRI machines.

Advanced countries are making use of powerful electromagnets to move trains at very high speed. These trains are called maglev trains (abbreviated from magnetic levitation).These trains float on a guideway and do not run on steel rail tracks. Instead of using a engine based on fossil fuels, they make use of magnetic field forces. The magnetized coils are arranged in the guide way which repels the strong magnets placed in the train's under carriage. This helps train move over the guideway, a technic called electro - dynamic suspension. When current passes in the coils of guideway , a typical magnetic field is set up between the undercarriage of train and guideway which pushes and pull the train along the guideway depending on the requirement. The lack of friction and its aerodynamic style allows the train to more at very high speed. (i) The levitation of the train is due to
