Permanent magnetic bar/rod/tube 3000-12000Gauss
1. Structure
Magnetic bar are made from “Neo” (NdFeB) Rare Earth magnets assembled in repulsion. The magnets are encased in a food quality 304 or 316 stainless steel casing that is welded sealed, cleaned and then polished.It is seamless and waterproof, no liquids or supper fine powder or gas can penetrate the interior of magnetic system.

6000/8000/10000/12000/14000/16000 GaussThe working environment of the magnetic rod determines that it must have certain corrosion resistance and high temperature resistance, and some occasions require relatively strong magnetic induction intensity. Different magnetic induction intensity can be obtained by using different thicknesses of magnetic sheets. The choice of different magnet energy determines the maximum magnetic induction strength and temperature resistance of the magnetic bar. Generally, in order to achieve a surface magnetic induction strength of more than 12000 Gauss on a conventional 1-inch diameter magnetic bar, N40 or more types of Ndfeb magnetic steel are required. High temperature resistant magnetic bar in the temperature of more than 150 degrees above the general choice of samarium cobalt magnetic steel. However, the large diameter magnetic bar does not choose samarium cobalt, after all, the price of samarium cobalt is very high, and the price of a magnetic bar with a diameter of 50*500 reaches tens of thousands of yuan.
The magnetic induction intensity of the surface of the magnetic bar is proportional to the smallest particle size that can be adsorbed, and small iron impurities in batteries, pharmaceuticals and other fields can also have a great impact, so a magnetic bar of about 12000 Gauss should be selected. Other areas can choose a lower.
