    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.

    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.

    Ferrite Cores

    Often used as inductors and transformers in electrical circuits, these cores generate a magnetic hold when magnet wire (sold separately) is wrapped over them and energized. Remove the electric current and the cores lose their magnetism.
