A: The main shapes of sintered NdFeB magnets are disc round, square, cylinder, ring, tile and various special-shaped products. In actual production, large blanks are produced first, and then finished ...

A: Neutral salt spray test Neutral salt spray test is to spray salt water containing (5± 0.5)% sodium chloride with a pH value of 6.5 ~ 7.2 through a spray device in a specific test box, let the salt...

A: The working principle of the Gauss meter is mainly based on the application of the Hall effect: when a current-carrying conductor is placed in a magnetic field, due to the Lorentz force, a transver...

A: Since the advent of NdFeB permanent magnet materials, it has attracted much attention because of its superior magnetic properties. We generally use remanence, coercive force and maximum energy prod...

A: -- Do all sintered NdFeB magnets need coating? Sintered NdFeB permanent magnet materials are produced by powder metallurgy process. It is a powder material with very strong chemical activity....

A: Take grade N35 as example, letter "N" is short for neodymium, directing to the magnet type, the number “35” means a neodymium magnet has a maximum energy product of 35MGOe. It refers to the maximum...

A: The amount of magnetism [brmax at the center] of a magnet is measured in Gauss. This is a measure of the penetration of a magnet. Below is a table of the Gauss ratings of the most popular neodymium...

A: There are 2 types of magnets: permanent magnets and electro-magnets. Permanent magnets emit a magnetic field without the need for any external source of power. Electro-magnets require electri...

A: Most commonly, Gaussmeters, Magnetometers, or Pull-Testers are used to measure the strength of a magnet. Gaussmeters measure the strength in Gauss, Magnetometers measure in Gauss or arbitrary units...

A:WHAT ASPECTS NEED TO BE COMMUNICATED WHEN PURCHASING? - How to prepare an inquiry for magnets? - What details must be clarified in order to obtain an accurate quotation and delivery date? If ...
