What are some uses of industrial magnets?

Electric guitar pickups use magnets.

Industrial magnets come in a wide variety of types, shapes, sizes and wattages. They are used across a broad spectrum of industries for an equally diverse set of purposes. Specific uses of industrial magnets depend on specific requirements.

The Magnetic Materials Producers Association (MMPA) and the Magnetic Distributors and Fabrications Associations (MDFA) set industry standards for the production and testing of magnets. It is helpful to consult your 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 are the automobile, electronics, plastics, glass and ceramics, shipping, construction, mining, food and pharmaceutical industries. They use magnets to facilitate production and to generate energy. Magnets are also used in the implementation of industry protections.

Magnets can be used in conveyors, plates, assemblies, separators, magnetized pulleys, tube grids, 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 out any iron particles that may have inadvertently become mixed with food or medicine. Magnetic sweepers at airports, docks and construction sites collect any scrap iron that would otherwise endanger traffic or puncture tires. By detecting scrap metal before any damage is done, they avoid repair expenses.

Industrial magnets lift, hold, carry, stack and drop heavy loads. This is very useful in construction, transport, manufacturing and mining. Magnets are also used in salvage operations and can help dredge large items from the ocean floor.

Magnets, in permanent and electromagnet combination, 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 such as televisions, radios, CRT computer monitors, CD drives, speakers, microphones, watches and sensors all contain magnets. Magnets are used in amplifiers, electric guitar pickups, transformers, actuators, compasses and toys.

Magnets are used in Maglev trains. Maglev’s complete 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 480 km/h.
