    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.

    NdFeB Magnet N40 Magnetic Grades and Temperature:
    The Grade of a magent directly refers to the Maximum Energy Product of the material that composes the magnet. It in no way refers to the physical properties of the magnet. Grade is generally used to describe how “strong” a permanent magnet material is. The energy products is specified in the unites Gauss Oersted.
    One MGOe is 1,000,000 Gauss Obersted. A grade forty (N40) would have a Maximum Energy Product of 40 MGOe.The higher the grade the “stronger” the magnet. Disc Neodymium Magnet N38 Ni
    Magnetic materials have a wide range of working temperatures. The following chart the various materials and their maximum working temperature. NdFeB material comes in many different heat tolerances but as the heat tolerance increases the maximum available fulx density decreases:
