What Are Magnets Used For?

Magnets are composed of atoms such as iron, cobalt, and nickel. The internal structure of the atoms is quite special and they have a magnetic moment. Magnets can generate magnetic fields and have the property of attracting ferromagnetic materials such as iron, nickel, cobalt, and other metals. In this article, let’s take a look at what are magnets used for.

There are four common permanent magnets available on the market today, namely neodymium magnets, alnico magnets, ferrite magnets, and SmCo magnets. Different types of permanent magnets have different uses.

Common uses of ferrite magnets include school projects, loudspeakers, guitar pick-ups, eddy current devices, breaks & clamps, motors & generators, switches, relays, security systems, sweeper magnets, crafting projects, model making, DIY home projects, science experiments, classroom displays, store signage, office organization, home decor, retail displays, lifting machinery, fridge magnets, apparel, whiteboards, promotional gifts, etc.

Common uses of neodymium magnets include magnetic resonance imaging,  magnotherapy, audio equipment, lifting large loads, flying, business displays, and signage, do-it-yourself projects, home, and wall decor, stationery, and business supplies, jewelry, hobbies, etc.

Common uses of alnico magnets include guitar pick-ups, electrical motors, bearings, traveling wave tubes, aerospace components, rotating machinery, sensors & sensing devices, meters & instruments, harsh environment equipment, high-temperature handling equipment, heat treatment jigs, medical devices, industrial machinery, microphones, robotics, communications, industrial automation equipment, actuators, military radar equipment, magnetars, security systems, etc.

Common uses of SmCo magnets include high-performance motors, actuators, generators, turbomachinery, electric motors, magnetic separation devices, traveling wave tubes, magnetic couplings, magnetic bearings, sensor systems, drilling equipment, wind turbine equipment, energy recovery systems, medical devices, missile components, industrial automation equipment, pipeline inspection, robotic arms, gyroscopes, accelerometers, particle accelerators, sputtering deposition, magnetic drive components, Halbach Arrays and more.
