Magnet systems made of neodymium with and without a rubber coating
Our practical magnet systems are real all-rounders that will serve you well in trade and everyday life. Do you need a practical holder for hanging clothes, kitchen utensils or the like? Would you like to equip doors and cupboards with magnets that adhere quickly? Our magnet shop provides you with everything you need.
What is a magnet system?
A magnet system is always used when different magnets are built into a system to deflect the field lines and thus to bundle the adhesion (magnetic force) on one side of the system. This focusing enables a higher adhesion factor. In addition, the magnet in the magnet system can optionally be protected by a rubber coating. The rubber coating of our rubberized magnets is made of Santoprene®. In the magnet shop we carry the magnet systems (neodymium) with and without a rubber coating in various designs (see above).
Why is neodymium used for the magnet systems?
Neodymium magnets are also commercially available under the designation neodymium-iron-boron or NdFeB magnets and have a much higher adhesive force than ferrite magnets. Neodymium is one of the "rare earths". Magnets made from this material are also often referred to as super magnets, as they are considered to be the strongest permanent magnets in the world. So, it is not surprising that as early as 1963, author Stan Lee and illustrator Jack Kirby (Marvel Comics) created a superhero named Magneto, who not only amazed children with his magnetic superpowers. We offer these superpowers for specialists and other users in the form of rubberized neodymium magnets and those without a rubber coating.
What is the difference between magnet systems made of neodymium with a rubber coating and a raw magnet?
A raw magnet is magnetic at the end faces and distributes the field lines relatively widely around the magnetic plates. As a result, it has a comparatively low adhesion factor or a low magnetic force. A magnet system, on the other hand, describes all magnets that are inserted into different pots - or systems.
In this way, the field lines are deflected and the adhesion is bundled on one side of the system. This focusing enables a higher adhesion factor. In addition, the raw magnet in the magnet system is protected by the rubber coating. The magnetic rubber of our permanent magnets is made of Santoprene®.
A raw magnet always shows its advantages when a non-magnetic material is present between the magnet and the effective surface. A raw magnet is recommended for this application.
Why are the magnet systems offered with a rubber coating?
The rubber-coated adhesive surface and the rubber coating protect the metal support surfaces from scratches and increase the pushing force. In a magnet system, the magnets are arranged alternately on the adhesive surface. This combination of magnets within the systems brings the maximum possible adhesive effect.
Why are magnet systems made of neodymium so strong?
Neodymium magnets are also considered super magnets because they have an extremely high adhesive force. Some models can support six hundred times their weight. They are therefore increasingly used in industry as load lifters or workshop magnets. When you buy our magnet systems, you benefit from their power.
Excursus: Magnet systems as pickups in turntables
The term magnet system is also used for the coils and magnets in the stylus of turntables. These have little in common with the magnet systems here in the magnet shop - even if they are also referred to as "magnet systems". For the inquisitive, we briefly explain the systems in turntables below. There are essentially two technologies here:
- "Moving Magnet" systems
The MM system (also: "Moving Magnet") in the pickups of turntables has moving magnets which are coupled to the stylus, which induce their tension in the stationary coils.
- "Moving Coil" systems
The MC system ("Moving Coil") or dynamic system has moving coils that are coupled to the stylus of the turntable. Voltage is induced in this by fixed magnets. Moving magnet systems are more common in turntables because they are considerably cheaper.
