There will be a magnetic attraction force between two objects containing charge with the same direction of motion, whereas, objects with charge moving in opposite directions have a repulsive force between them. An MRI magnet is very strong thousands of times more powerful than common kitchen magnets. These m… The shape of a magnet, however, can tell you a lot more than size. Magnets can help collect all the nails which are scattered on the ground after a repair job. Refrigerator magnets hold papers, bottle openers and other small items to the metal refrigerator door. Transcranial magnetic stimulation (TMS) is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. The magnetic force is an invisible force , so , we use the iron filings to see the magnetic field that is formed by the effect of magnetic force , The magnetic field around the magnet takes a regular shape , the greatest magnetic force of the magnet is concentrated at the two poles of magnet . Mines use magnetic sorting machines to separate useful metallic ores from crushed rock. They convert mechanical energy into electrical energy. Small magnets can be improved to increase strength by using different materials. The dark strip on the back of debit and credit cards is of magnetic nature and are used to store data just like computers’ hard drives. A doctor injects a magnetically-sensitive fluid into the cancer area and uses a powerful magnet to generate heat in the body. Magnets are found in some commonly used medical equipment such as and Magnetic Resonance Imaging machines. The property of attracting magnetic substances with the help of is called magnetism. Magnets in electric generators turn mechanical energy into electricity, while some motors use magnets to convert electricity back into mechanical work. Advertising magnets can take over your fridge. Each magnet’s shape has an influence how it is used. Magnets alter the direction of a magnetic material on a hard disk in segments that then represent computer data. Magnets are used in MRI machines which are used to create an image of the bone structure, organs, and tissues. Some types of hospital equipment use magnets to help doctors look inside of the human body. In recycling, electrically-powered magnets in cranes grab and move large pieces of metal, some weighing thousands of pounds. The trains carry powerful linear motors which push against magnets laid in the special track. The magnetic force is a part of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges.
