Why demagnetize magnets?
In general, you can send the demagnetizers directly or have an expert perform the process. It is demagnetized by applying an opposite magnetic field to the product to reduce the flux density.
That might sound fun at first, of course. Demagnetize a magnet? Why is that? After all, they're there to be magnetic. If we are talking about a magnet destined and created with this intention, surely. But there are also other objects made of magnetically conductive material that become magnetic over time, even if they were not originally magnetic. Now it makes a little more sense if an object was not created magnetically and this is not really, it is disturbing and undesirable when it suddenly attracts other materials.
In production processes, for example, this can be extremely cumbersome, can cause extreme delays in production and therefore cost a lot of money. Since it is important to demagnetize exactly such magnets, practically new and involuntarily formed.
How do these metals become magnetic?
In most cases, these are steel products or metal tools. You don't even have to do anything special to magnetically charge them. Whether by daily use, by welding or grinding, as well as by magnetic transports or vibrations, they can be magnetized.
What's the big deal? We've already mentioned that. Materials that are not desired there can be introduced into the production process, welding becomes difficult or even impossible, measurements can be distorted and, of course, a large amount of additional dirt is attracted, which contaminates the production process and therefore also affects the quality of the final product.
Since these serious problems occur frequently and easily, it is especially important to regularly inspect machines and products to avoid them and, if necessary, demagnetize newly formed magnets.
What should be taken into account when demagnetizing?
In general, you can send the demagnetizers directly or have an expert perform the process. It is demagnetized by applying an opposite magnetic field to the product to reduce the flux density. To decide how to eliminate magnetism, attention must be paid to color, shape, type of speed, and quantity. Depending on what case exists and what the general constellation of factors looks like, another device is used to demagnetize the metals.
For example, the thicker the material, the more difficult it will be to demagnetize completely. It may also be that magnetism, for example, can only be eliminated on the outside, but the core is still magnetic. This means that while products can be demagnetized temporarily, the attraction returns even after a while.
