Since 2002 , focus on manufacturing and supplying various kinds of bonded ferrite magnets


Magnet manufacturer introduce powerful magnets knowledge and strong magnet

Strong magnet manufacturer introduces powerful magnets is that there is no additional magnetic field, can keep its own magnetic an object. According to different materials can keep ten years commonly, powerful magnets are available with a ferromagnetic materials, such as iron, nickel, etc. Magnet is a general term, is refers to has the magnetic, the actual component may not contain iron. Relatively pure iron itself has no strong magnetic metallic state, only near the powerful magnets can produce magnetic induction, generally strong magnets inside and other impurity elements such as carbon to make magnetic stabilized, but it will reduce the electronic freedom and less prone to conduct electricity, so the current through the bulb light up, iron is a common magnetic elements, but many other elements have a stronger magnetic, like many powerful magnet is mixture of neodymium, iron, boron, etc. In addition, the magnet manufacturers need to use strong magnet materials must have high long broad hysteresis loop, because of this, when the external magnetic field is zero, can still have relatively strong magnetization; If you want to change the magnetization into zero, will be expected to exert strong external magnetic field.
