A type of magnetic force with strong magnetism
Magnetic types of Super Strong Magnets: In the absence of an external magnetic field, due to the exchange of electrons or other interactions between adjacent atoms in the magnetic domain, their magnetic moments overcome the influence of thermal motion, strong magnets are in a partially cancelled ...Read more -
Ferrite or neodymium magnets for horn magnets?
High-power woofer is generally use China Ferrite Magnet because of its high power and high temperature in the magnetic gap. General neodymium magnet may cause irreversible magnetic decline, but ferrite is generally fine. This more than likely stems from the same price, when it comes to the size o...Read more -
Magnets of different materials can be machined into different shapes and sizes
NdFeB magnets are very magnetic. You should avoid holding your hands or other parts of your body with magnets in the first place. The main raw materials for the production of Ndfeb Neodymium Magnet are metal neodymium, metal praseodymium, pure iron, aluminum, boron-iron alloy and other raw materi...Read more -
Composition and performance characteristics of artificial magnets
The composition of the artificial magnet is based on the magnetization of various metals, according to the need. A magnet approaches (touches) a magnetic substance that is induced at one end to form a namesake pole and at the other end to form a namesake pole. Classification of magnets A. Tempora...Read more -
Orientation and molding sequence of special-shaped magnets
Magnet, special-shaped magnet in the production process is difficult to do one-time processing forming. Magnet orientation and forming order: the magnetic powder of the magnet after orientation, molding and isostatic pressing made of blank density is very low, which is a negative factor in produc...Read more -
Analysis of demagnetization of a permanent magnet in magnetic pump
How to prevent demagnetization of a permanent magnet in magnetic pump, then we should first analyze the reasons why magnets demagnetization, which can be roughly divided into the following situations: 1. The use temperature is unreasonable. 2. Long time low head operation. 3. Pipes are improperl...Read more -
Whether the production technology is advanced or not directly determines the performance and quality of the magnet
