Strong magnet core and internal and external cladding composed of

Magnetic bar and internal and external cladding composed of a cylindrical magnet core also includes block 13,953,391,886 and guide magnet slices. Should do a good strong magnets spatial distribution of magnetic flux lines, the maximum magnetic flux density points are distributed as much as possible the entire root filled magnet, because the general is on the movement of goods and transmission lines, magnetic surfaces should be smooth and low resistance, free of environmentally harmful substances, avoid contaminated material and the environment. When using the magnetic wand consider material in contact with the process, the strong magnet inside the magnet may be part of the irreversible loss, loss exceeds the initial intensity of 30% or surface-coated stainless steel wear when broken, then the need to replace the magnetic tools, We should not continue to use.
