NdFeB magnets can be divided into two kinds of sintered NdFeB and Bonded NdFeB. Actually bonded injection molding, and sintering is heated to high temperatures by vacuum molding!

Powerful magnets refer to NdFeB magnets. It compared to ferrite magnets, alnico, samarium cobalt greatly beyond the magnetic properties of several other magnets

what is the magnetic properties of permanent magnetic materials, which indicators are included?

Why the permanent magnet material demagnetization curve at any measurement point on the magnetic polarization strength J value and the magnetic induction B value must be less than the remanence Jr and Br value?

In the demagnetization curve of the permanent magnetic material, when the reverse magnetic field H increases to a certain value bHc, the magnetic induction B of the magnet is 0

Broadly speaking, all magnetic materials that can be magnetized by magnetic fields, in which the magnetic properties of the materials are mainly utilized, are used as magnetic materials.

There are many types of magnets. Generally divided into two categories of permanent magnet and soft magnetic. We refer to the magnet, generally refers to the permanent magnet. Permanent magnets are divided into two categories: The first category: metal alloy magnet, including NdFeB magnet Samarium cobalt magnet, Alnico magnet

Strong magnet is generally aluminum-iron boron structure, the normal magnet according to what you mean should be an ordinary ferrite material. Rare earth NdFeB magnets (commonly known as: strong magnets, electroplated magnets, magnets) is a unique rare metal doping some other synthetic materials made of sintered metal.
