Our very own Magnetenspecialist Edition. A set of powerful race number magnets in black featuring Magnetenspecialist’s distinctive white “m” logo.
These race number magnets were developed based on our many years of expertise with neodymium magnets. Instead of using a separate, unprotected magnet, we opted for a design in which the neodymium magnets are fully encased within the 3D-printed part. This provides better protection against moisture, sweat, and friction during exercise.
A complete set consists of 8 pieces: 4 magnets for the front and 4 for the back. Place your race number between them, and the magnets will hold it securely in place—without safety pins and therefore without holes in your sportswear.
The magnets are compact, lightweight, and reusable. After your match, simply snap them back into the round holder so you can keep the entire set neatly together.
Specifications: set of 8 • powerful neodymium magnets • fully embedded in the 3D-printed piece • includes a round storage holder • reusable • black and white • developed by Magnetenspecialist in Nuenen.
No pins. No holes. But there are magnets.
According to the declarations of conformity provided by the manufacturer, this product complies with the current European RoHS Directive and REACH Regulation.

Neodymium magnets are very powerful and can bounce off each other and/or iron objects at high speed. The force increases as the magnet gets larger, which also increases the risk of breakage. Two of the larger magnets in our range are powerful enough to break fingers or at least cause a few large blisters.
Therefore, wear work gloves and keep magnets away from children. Also, keep Neodymium (NdFeB) magnets at a safe distance from people with pacemakers. This also applies to electronic devices and payment cards.
Neodymium magnets are still the most powerful magnets available today. Our super-strong magnets also remain magnetic virtually indefinitely, provided they are not exposed to the maximum operating temperature or are used with opposite poles.
The letters and numbers in the material coding have the following meaning: The N stands for Neodymium, the subsequent digits indicate the maximum magnetic energy expressed in MgOe. If there are no further letters after this, the magnet can be used up to 80 degrees Celsius.
If there are still letters behind it, it can reach a higher temperature.
We indicate adhesive force in grams or kilograms because this appeals to more people than Newton. The indicated force is measured perpendicular to the magnet. The adhesive force is the force required to pull a smooth, flat steel object (ST37) at least 10 millimeters thick from the magnet in question.
This force quickly diminishes when, for example, there's a gap or layer of paint between the magnet and the object. Even half a millimeter can reduce the force by half. A steel alloy or a rough surface also significantly reduces the holding force.
As mentioned, the direction of the adhesive force is perpendicular to the magnet, but the shear force is much smaller and also depends on the friction between the magnet and the object.
