    About Magnets
    industrial info icon

    Choose a magnet with the right strength, material, and temperature resistance for your application.

    Hardwire Electromagnets

    Position the face of these magnets in direct contact with a flat metal surface and turn on the power to create a magnetic hold. Magnets have wire leads that connect to a DC electromagnet power supply (sold separately). Holding power is not adjustable. When turned off, the magnet will still have some residual magnetism.
    Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

    Spring-Loaded Release—Magnets with spring-loaded release have a pin that pops up to separate the object and magnet when the power is turned off.

    Plug-In Electromagnets

    Position the face of these magnets in direct contact with a flat metal surface and plug in to create a magnetic hold. The plug contains a transformer that converts power from AC to DC, so no additional wiring or power source is needed. Holding power is not adjustable. When turned off, the magnet will still have some residual magnetism.
    Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

    Hardwire Electromagnets with Parallel Poles

    Parallel poles create a better magnetic hold on thinly painted, plated, or coated flat metal surfaces than other magnets. A terminal block on the magnet connects to a DC electromagnet power supply (sold separately). Holding power is not adjustable. When turned off, the magnet will still have some residual magnetism.
    Warning: Maximum pull ratings are based on direct contact with rust-free and unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

    Plug-In Magnetic Yokes

    Image of Product. Front orientation. Magnetic Yokes. Plug-In Magnetic Yokes.
    Find welding defects and other flaws in magnetic materials. These yokes create a magnetic field that draws magnetic powder (not included) to imperfections, making them easy to spot. All operate on AC power, which creates a small magnetic field ideal for detecting flaws along the surface of materials. Powered by standard electrical outlets, these yokes have a reliable and consistent power source.
    Attach an LED light to your yoke to brightly illuminate inspection areas. They’re powered by the yoke’s magnetic field, so they don’t require batteries.
    Calibrate your yoke before each use with a test weight to ensure accurate test results.
    AC/DC Switch—Yokes with an AC/DC switch can also operate on DC power. DC power generates a deeper magnetic field than AC power to find defects underneath surfaces, such as internal tears and cracks.
