Neodymium Bar Magnet Ø8.9 × 50 mm N52 NiCuNi, diametrically magnetized is a very powerful neodymium bar magnet with strong N52 magnetization. Thanks to its cylindrical shape, this magnet combines a compact diameter with a length of 50 mm, making it ideal for technical applications that require strong magnetic performance.
The bar magnet is made of high-quality neodymium material (NdFeB). The high N52 magnet grade ensures very strong magnetic performance relative to its size.
The NiCuNi (nickel-copper-nickel) coating provides a sleek metallic finish and offers limited protection against corrosion and wear. As a result, NiCuNi-coated neodymium magnets are particularly suitable for use in dry indoor environments.
This bar magnet is diametrically magnetized, which means that the north and south poles are located on opposite sides of the cylindrical shell. The magnetic axis runs perpendicular to the diameter rather than from one end to the other. This makes the magnet particularly well-suited for applications such as sensors, motors, rotating systems, and other technical designs.

Specifications:
Please note: Neodymium magnets are very powerful and can break or shatter upon impact. Handle them with care and keep them away from electronics, pacemakers, and small children.
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.
