Magnets are found in many thousands of devices. The most historically used magnet would probably be the compass where a suspended magnetised needle points to magnetic north. Alternators, dynamos, electric motors etc. all use permanent or electromagnets and of course so does the magnetron in your microwave oven or the loudspeakers in your hi-fi. The most important recent use of magnets are in the MRI scanner now used in most hospitals to give very highly detailed pictures of the inside of the human body. The extremely powerful magnetic field is produced by coils cooled by liquid helium making them super conductive. From this to the simple handbag closure or fridge magnet, magnets are all over our homes and workplaces.
