Magnets of this volume and power are sometimes called ‘supermagnets’. Get aware of the strength, keep strictly away from children, use gloves. Handle with care and notice that metallic objects like keys or scissors nearby can be abruptly moved by its magnetic pull. Neodymium magnets are made of neodymium, iron and boron and are the strongest raw magnets. For more information please click here: facts about magnetism; safety precautions.
Large NdFeB Magnet Disc Round Nickel Supermagnet:
Neo’s are some of the strongest rare earth magnets known to man. Originally developed for the electronics industry they are increasingly being used for other applications where a very strong hold is required (inc. catches for handbags, holding applications, magnetic therapy products etc).
Huge quantities of standard sizes and shapes are kept in stock. If you are after something special, provide us with a drawing and we’ll make them especially for you (no tooling cost – you only pay for the magnet) .
Available as standard in N35 grade and nickel plated (other plated finishes and grades available on request).
Material: NdFeB magnet
