Questions and Answers
What are industrial magnets?
This concept covers a whole range of devices, from simple magnets for manual control of e.g. aluminum cans at scrap yards, to complex systems for separating metals from raw materials, as well as magnets that hold, grip and fix various metal objects.
Why do underwater search magnets in stainless steel housings have a lower load capacity?
Underwater exploration magnets come in two basic categories:
- stainless steel, where the magnet is in a tightly welded housing
- ordinary, lenticular
In underwater searches, when trawling water reservoirs, it is not the load capacity of the magnet that is most important, but the range of the magnetic field it generates. First of all, the housing of the stainless steel magnet creates a distance that reduces the static load capacity, and secondly, they are designed to attract on all sides. The magnetic lenticular holders are constructed differently, because one pole of the magnet acts directly, while the other one saturates the steel housing. This means that they only attract with one side. Thanks to this, a 5 cm diameter holder is able to support a weight of 140 kg (in laboratory conditions). Accuracy of workmanship is very important, because both the magnetic gap and the magnetic surface area of the face in relation to the thickness of the magnet is the result of many tests and measurements - that is why the MAGNEPOL company, as a precursor of search handles, offers the highest quality products.
