This is done as follows. Magnets have also been mentioned in ancient Indian and Chinese texts that date back to 6th century BC. Magnets are classified into two types based on their … A magnet is used to separate the useful magnetic substance like steel and iron from waste by the method of magnetic separation. Permanent magnets are used in hard drives, motors, cars, generators, televisions, phones, headphones, speakers, transducers, sensors etc. Magnets are used inside a generator to transform mechanical energy to. Motors use electrical energy and convert it into mechanical energy. Magnets attract or repel other magnets, but are also used … This energy is then used for various applications from pumping water to drilling. A similar application is employed in scrap processing plants too. Speakers and microphones also use permanent magnets to convert electrical audio signals into mechanical energy.
