    Custom Round Magnets & Disc Magnet Supplier

    Neodymium disc magnet, also known as NdFeB disc magnet, is a tetetic crystal system made of Neodymium, iron and boron (Nd2Fe14B).  The magnetic energy product (BHmax) of this magnet was greater than that of a samarium cobalt magnet, and the most commonly used rare earth magnet. Ndfeb magnets are widely used in electronic products, such as mobile phones, hard disks, earphones, and battery-powered tools.

    FAQ of Neodymium Disc Magnet

    If a substance wants to be magnetic, it needs to meet two conditions: one is that there are lone pair electrons in the outermost layer of atoms, and the other is that the atoms that make up the substance are arranged neatly. However, there are only a few metals in nature, such as iron, cobalt and nickel, that meet these two requirements at the same time.

    It is found that iron atoms have 26 extranuclear electrons, of which the outermost layer has a lone pair electron, and the outermost layer of cobalt and nickel atoms also has lone pair electrons. However, because the arrangement of magnetic domains, the small magnetic regions in these substances, is irregular, and the magnetic fields generated by these small regions cancel each other, these metals usually do not show the same magnetic force as magnets. However, under the action of external magnetic field force, the magnetic field direction of these magnetic domains is consistent, that is, they are magnetized, and the magnetized material will show magnetism externally.

    We can verify through such an experiment: if a coin is attracted by a magnet, the coin will be magnetized, and other ordinary coins will be attracted when they are close to the coin, indicating that the magnetized coin shows external magnetism.

    There are two types of magnets, one with permanent magnets and the other with non permanent magnets. It can be seen from the name that the magnetism of a permanent magnet can be maintained for a long time, and the demagnetization of a non permanent magnet will occur after a period of time. All natural magnets are permanent magnets, and only some rubidium magnets in artificial magnets are permanent magnets.

    In daily life, magnets may be degaussed if they are not careful. The essence of this phenomenon is that the position of the neat magnetic domain inside the magnet changes under the external action. The direction of the magnetic field generated by the magnetic domain is no longer unified, and the external magnetic field will no longer show magnetism. High temperature or fierce collision can easily make the magnet appear this kind of situation.

    In order to prevent magnetic mines, warships will also demagnetize the hull before launching. Since it is not possible to demagnetize warships with ordinary high temperature or impact, warships generally use devices that can generate magnetic fields in the opposite direction to those generated by the ship body to demagnetize.
