LAMINATED MAGNET ASSEMBLY LAMINATED MAGNET ASSEMBLY is to cut the whole magnet into many small pieces of magnet, and then use specific glue to bond together. These small magnets are insulated from each other and enable to cut down electromagnetic eddy current. When the permanent magnet motor is running, the motor will generate harmonic and [...]
Understanding Magnetic Permeability Magnetic Permeability is a value that expresses how a magnetic material responds to an applied magnetic field. If a material's internal dipoles become easily oriented to an applied magnetic field, that material is regarded as being a high-permeability material. If the material's internal dipoles do not become easily oriented to an applied [...]

Introduction to Magnetic Materials A magnetic material is a material that can react to a magnetic field in a certain way. It is called a magnetic material, and generally consists of a transition element such as iron, cobalt, nickel, and alloys thereof, which can directly or indirectly generate magnetism. Magnetic materials are generally classified into [...]
About Some Magnet Knowledge Permanent magnet material: The permanent magnet material is magnetized by an external magnetic field and does not disappear.
