Magnet systems made of neodymium with and without a rubber coating
Our practical magnet systems are real all-rounders that serve you well in crafts and in everyday life. Do you need a practical holder for hanging up clothes, kitchen utensils or similar? Would you like to equip doors and cupboards with fast-adhering magnets? Our magnet shop provides you with everything you need.
What is a magnet system?
A magnet system is always spoken of when various magnets are built into a system to deflect the field lines and thus focus the adhesion (magnetic force) on one side of the system. This focus allows for 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 have the magnet systems (neodymium) with and without rubber coating in different versions.
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 significantly higher adhesive force than ferrite magnets. Neodymium is one of the "rare earths". Magnets made of this material are often referred to as super magnets, as they are considered the strongest permanent magnets in the world. So, it's not surprising that back in 1963 author Stan Lee and illustrator Jack Kirby (Marvel Comics) created a superhero named Magneto, who amazed not only children with his magnetic superpowers.
We offer these superpowers for specialists and other users in the form of rubberized neodymium magnets and magnets without a rubber coating.
What is the difference between magnet systems made of rubber-coated neodymium and a raw magnet?
A raw magnet is magnetic on the end faces and distributes the field lines relatively widely around the magnetic plates. As a result, it has a comparatively low adhesion factor and low magnetic force. A magnet system, on the other hand, refers to all magnets that are inserted into different pots - or systems.
In this way, the field lines are deflected, and the adhesion is concentrated on one side of the system. This focus allows for a higher adhesion factor. In addition, the raw magnet in the magnet system is protected by the rubber coating.
A raw magnet shows its advantages whenever there is a non-magnetic material between the magnet and the effective surface. A raw magnet is recommended for this application.
Buy magnet systems: Why are the magnet systems offered with a rubber cover?
If the magnet is rubberized, the rubber-coated adhesive surface and the rubber coating protect the metallic carrying surfaces from scratches and increase the pushing force. In a magnet system, the magnets are arranged with alternating polarity on the adhesive surface. This combination of rubberized magnets within the systems provides the maximum possible adhesive effect.
Why are neodymium magnet systems so strong?
Neodymium magnets are also considered super magnets because they have an extremely high adhesive force. Some models can hold six hundred times their weight. Therefore, they are increasingly used in industry as load lifters or workshop magnets. When you buy our neodymium magnet systems, you benefit from their power.
Excursion: Magnetic systems as pickups in turntables
The term magnetic system is also used for the coils and magnets in the styluses 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 those who are curious, we briefly explain the systems in turntables below. There are essentially two technologies here:
The MM system (also: "moving magnet") in pickups of turntables has moving magnets which are coupled to the stylus, which induce their voltage in the fixed coils.
The MC system ("Moving Coil") or dynamic system has moving coils which are coupled to the stylus of the turntable. Voltage is induced in these by fixed magnets. The moving magnet systems are more common in turntables because they are considerably cheaper.
