Arthritis Magnetism How is it used today? Toys!!!! Electronics!! There was a well-done pilot study examining the use of magnets in post-polio patients who suffered from musculoskeletal trigger point pain, mostly in their backs. Magnetar A magnetar is an exotic kind of neutron star–a city-sized ball of neutrons created when a massive star's core collapses at the end of its lifetime. A magnetar typically possesses a magnetic field more than one quadrillion times (one followed by 15 zeroes) stronger than the earth's magnetic field. If a magnetar were located halfway to the moon, it could wipe the data from every credit card on earth. Medicine!!??? A generator converts mechanical energy into electric energy by moving a conductor through a magnetic field. Transportation The speaker makes sound by letting current go through a coil that is wrapped around the long part of a magnet. When you put vibrations on the coil, it moves the speaker cone, when you stop vibrating it, the magnet pulls it back to the center point. These Polly Pocket dolls use the magnets to
attract them to eachother and to work with
their playset that often comes with them. The
magnets are 1/8inch in diameter, and can come
out really easily. Magnets A magnet is a material or object that produces a magnetic field. The magnetic field it produces is invisible but is responsible for the most notable property of a magnet: a force that pulls on other materials like iron and attracts or repels other materials.
