A magnet is an object with its own field. Neodymium rare earth magnets are permanent and are characterized by the following parameters:
the presence of a special coating (nickel, zinc, etc.);
various manufacturing methods: telescopic handles, discs, plates, "tablets", rods, cubes, sectors, rings, etc.;
permissible exposure temperature is 80-200 degrees;
forms: two- and one-sided;
views in the direction of the field: radial, axial, diametrical.
If we consider the forms, then they are one-sided Polish neodymium magnets demonstrate the same power as bilateral ones.
Regardless of the coating, these items have excellent performance characteristics. Yes, demagnetization of any kind occurs only by 2% in 10 years.
Where
Recently, the popularity of neodymium magnets has increased, due to which they penetrate into various spheres of activity. High operational properties allow the items to be used in the production of radio equipment, high-precision equipment, measuring instruments, medical equipment, mobile gadgets, household appliances, etc.
High demand for neodymium magnets is demonstrated by manufacturers of wind generators and energy complexes.
Neodymium is also an important element of search magnets. Yes, magnetic fishing, which uses neodymium elements, is gaining popularity recently.
operating rules
Neodymium magnets have a significant magnetic force, so they can be dangerous in inexperienced hands. In order to avoid injuries in production and everyday life, large neodymium magnets must be kept at a distance of at least 1 meter from each other and from iron objects.
If a limb or skin were pinched between magnets, it is necessary to place spacers made of materials that are not magnetized (wood, plastic).
Magnets up to 4 cm can also be dangerous, leaving cuts, hematomas and bruises on the skin. A child may accidentally swallow them during play.
It is also necessary to keep in mind that a large number of neodymium magnets or their large dimensions create a powerful field that can lead to failure or failure of precision equipment such as computers, smartphones, watches, pacemakers, and even bank cards. Keep them away from household appliances in wooden boxes.
