An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic ).
Ring magnets Most hard disk drives incorporate strong magnets This manually-powered flashlight uses a neodymium magnet to generate electricity Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the ...
Magnetic separation equipment is used for separating magnetic from nonmagnetic material, for example separating ferrous metal from other material in scrap. Industrial lifting magnets; magnetic levitation, used in a maglev train or trains; Induction heating for cooking, manufacturing, and hyperthermia therapy
Neodymium magnets have been tested for medical uses such as magnetic braces and bone repair, but biocompatibility issues have prevented widespread applications. [85] Commercially available magnets made from neodymium are exceptionally strong and can attract each other from large distances.
A very common source of magnetic field found in nature is a dipole, with a "South pole" and a "North pole", terms dating back to the use of magnets as compasses, interacting with the Earth's magnetic field to indicate North and South on the globe. Since opposite ends of magnets are attracted, the north pole of a magnet is attracted to the south ...
The items we use in everyday life have become such intrinsic parts of our lives, that we've stopped wondering why they are the way that they are a long time ago. From clothes pegs and spaghetti ...
15 Unusual Uses for Common Household Items. AOL.com Editors. Updated October 16, 2017 at 1:33 PM. 15 Unusual Uses for Common Household Items.
Most common audio magnets, including those used in loudspeakers and electromagnetic instrument pickups, are ferrite magnets. Except for certain "vintage" products, ferrite magnets have largely displaced the more expensive Alnico magnets in these applications. In particular, for hard hexaferrites today the most common uses are still as permanent ...
