    The Most Important Business Uses of Strong Magnets


    The strongest permanent magnets available on the market today are known as neodymium magnets. Neodymium magnets are the most widely used type of rare-earth magnets, made from an alloy of iron, neodymium, and boron.

    These ultra-strong magnets boast branching applications in the business world. Strong magnets feature in several modern devices, including microphones, smartphones, MRI scanners, generators, and more.

    Because neodymium magnets are so strong, even the tiniest of magnets are effective and thus exceptionally versatile. Read on to learn more about the potential business applications of strong magnets.

    MRI (Magnetic Resonance Imaging)

    One of the most vital applications of strong magnets in the business world involves medical imaging. During an MRI scan, neodymium magnets affect your body’s protons, producing detailed images of the result. 

    In hospitals around the world, “open” MRI machines employ large neodymium magnets to diagnose severe conditions and potentially save lives.

    Smartphones and audio devices

    Every smartphone features essentially “invisible” neodymium magnets. Critical to your phone’s function, these tiny magnets work behind-the-scenes within several parts of the phone. These parts include:

    - Speakers

    - Receivers

    - Vibration mode motor

    - Haptic feedback motor

    - Camera auto-focus

    Some smartphone components, such as speakers and receivers, originally featured a single, larger magnet. With the advent of thinner smartphone designs, smaller, stronger magnets are now necessary.

    Speakers are typically controlled by an electric current and two strong magnets. To construct a speaker, manufacturers suspend an electromagnetic coil near a fixed magnet. To produce sound, an electric current is then quickly pushed through the coil. As the coil charges, it becomes attracted to the magnet and then repelled, causing amplified vibrations.  These vibrations produce the sounds we hear through the speaker.

    Advertising and retail

    Strong magnets boast several applications within the retail industry. Point-of-sale displays, for example, are often held together using strong but tiny magnets. Pairs of magnets are also often used in the production of brochures, menus, and printed packaging.

    As another retail application, jewellers commonly use small magnetics for jewellery production and to create jewellery clasps. Counter-bored neodymium magnets, featuring opposite poles on each counter-bored face, generate a highly secure and durable hold.

    Because neodymium magnets are so strong, magnets as small as 5mm in diameter are effective in jewellery production.

    Since traditional jewellery clasps can be delicate and fussy to work with, magnetic jewellery claps make it easier to open and close a clasp. 

    Generators and engines

    Both electromagnets and permanent magnets play a critical role in the function of engines and generators. In electronic motors, the combination of electromagnets and neodymium magnets converts electricity into mechanical energy.

    Conversely, generators convert mechanical energy into electricity by pushing a conductor through an electric field.


    Strong magnets are essential to the functioning of many modern devices. Any business based in the electrical, medicinal, renewable energy, or jewellery industry will benefit from investing in quality neodymium magnets.

    Along with their use in electrical devices, strong magnets are also used for door locks, storage, dentures, crafts, point-of-sale displays, and much more.
