Electric guitar pickups use magnets.
Industrial magnets come in a wide variety of types, shapes, sizes, and strengths. They are used across a broad spectrum of industries for an equally diverse set of purposes. The specific uses of industrial magnets depend on specific requirements.
The Magnetic Materials Producers Association (MMPA) and the Magnetic Manufacturers and Distributors Associations (MDFA) set the industry standards for the production and testing of magnets. It is helpful to refer to their publications when selecting magnets for a particular industry. Some commonly used industrial magnets include permanent magnets, electromagnets, ferrite, samarium, rubber magnets, sheet magnets, and neodymium.
Cranes can use industrial magnets to move loads.
Industries that regularly use industrial magnets in their operations include the automotive, electronics, plastics, glass and ceramics, marine, construction, mining, food, and pharmaceutical industries. They use magnets to facilitate production and generate energy. Magnets are also used to implement industrial protections.
Magnets can be used in conveyors, plates, assemblies, spacers, magnetized pulleys, pipe racks, chutes, and cranes. Magnets are needed to separate ferrous impurities from non-ferrous matter. They separate metals from ore in the mining industry.
Electromagnets are used to convert electrical energy into mechanical energy in electric motors.
In the food and pharmaceutical industry, magnets pick up any iron particles that may have been inadvertently mixed with food or medicine. Magnetic sweepers at airports, docks and construction sites pick up any scrap metal that would otherwise endanger traffic or puncture tires. By detecting scrap metal before damage occurs, they avoid repair costs.
Industrial magnets lift, hold, carry, stack and drop heavy loads. This is very useful in construction, transportation, manufacturing, and mining. Magnets are also used in salvage operations and can help dredge up large items from the ocean floor.
Magnets, in combination permanent and electromagnetic, are used in electric motors to convert electrical energy into mechanical energy. The same combination is used in generators to convert mechanical energy into electrical energy.
Electronic products like televisions, radios, CRT computer monitors, CD drives, speakers, microphones, clocks, and sensors have magnets. Magnets are used in amplifiers, electric guitar pickups, transformers, actuators, compasses, and toys.
Magnets are used in Maglev trains. The entire Maglev form is magnetically levitated. The magnets at the bottom of the train and on the tracks repel each other. Due to this repulsion, these trains actually float or levitate above the tracks. This decreases friction and increases the speed of the train. Maglev trains, first introduced in Japan in 1997, can travel at speeds of up to 300 mph.
