Pulling power decreases sharply per each millimeter of distance. Keep in mind that even a microscopic distance (e.g., dirt, paint, rust) noticeably reduces the pull force. Magnets work optimally in perfect adhesion; gap nullifies the power. See how flashily the parameters fall, when the product does not adhere tightly to the metal substrate. When planning the arrangement, eliminate redundant distances.

This section indicates the approximate holding capacity sufficient to initiate the shifting of the magnet down on a vertical steel plate (assuming standard friction). This parameter varies with the gap size between the magnet and the metal.

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	9.71 kg / 21.41 lbs 9710.0 g / 95.3 N

When mounting a magnet on a upright wall (e.g., a car body), it will only hold just about 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip mean that magnets slide down easier than they pull off. Planning a hanger? Consider that the shear force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slip down under a much lighter cargo. Using a rubber coating can effectively raise the stability.

12 mm	100%	48.55 kg / 107.03 lbs 48550.0 g / 476.3 N

A thin sheet cannot focus the full magnetic flux, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the field will pass right through and the pull force will drop sharply. To utilize 100% of this neodymium's power, you require a sufficiently solid piece of steel. The saturation phenomenon causes that on delicate walls (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel thickness from these parameters.

Standard neodymium magnets irreversibly lose power past the thermal threshold. Watch out for overheating – high temperature can permanently demagnetize this product. With increasing heat, the neodymium's capacity temporarily lowers. Refrain from using this product close to heaters exceeding its operating temperature limit. Too high temperature will cause permanent loss of magnetic properties.

*Important note: Temperature resistance is determined by both grade, but also on the magnet's shape. Thin magnets (pancake types) may lose charge permanently sooner than long magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnets attract each other from a wider radius than a magnet and sheet setup. The setup of two magnets creates a more powerful interaction and a further horizon of operation. Want to build a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Remember that when connecting a pair of magnets, the pinch force is massive. The repulsion force is a bit weaker than the connection force, but still large.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the geometric center of the gap (due to field cancellation).
Attention: Figures show shear force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a real danger to IT equipment and medical implants. These magnets produce a flux that destroys function of sensitive medical devices. Be aware: the unseen radiation acts through matter and plastic. Special caution must be taken by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Kinetic force can cause material chips or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when handling with powerful specimens.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Sliding resistance

*Note: On a vertical surface, the magnet retains only a fraction of its perpendicular strength.

2. Steel saturation

*Thin steel (e.g. computer case) drastically weakens the holding force.

3. Temperature resistance

*For standard magnets, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.44

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The P_c (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher P_c value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

The offered product is an exceptionally strong rod magnet, composed of durable NdFeB material, which, at dimensions of Ø45x15 mm, guarantees maximum efficiency. The MW 45x15 / N38 component is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 48.55 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building generators, advanced sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 476.32 N with a weight of only 178.92 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø45x15), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 45 mm and height 15 mm. The value of 476.32 N means that the magnet is capable of holding a weight many times exceeding its own mass of 178.92 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 45 mm. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized diametrically if your project requires it.

Strengths and weaknesses of rare earth magnets.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:

They do not lose power, even over nearly ten years – the drop in power is only ~1% (according to tests),
Magnets effectively protect themselves against demagnetization caused by external fields,
The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnets possess excellent magnetic induction on the working surface,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of custom modeling and adapting to complex applications,
Fundamental importance in high-tech industry – they serve a role in hard drives, electromotive mechanisms, diagnostic systems, as well as technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in small systems

Disadvantages

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating nuts and complicated forms in magnets, we recommend using casing - magnetic mount.
Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small components of these devices are able to complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what it depends on?

The specified lifting capacity concerns the maximum value, recorded under optimal environment, meaning:

with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
possessing a thickness of minimum 10 mm to ensure full flux closure
with an ground contact surface
without any clearance between the magnet and steel
during pulling in a direction vertical to the plane
at temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

During everyday use, the actual lifting capacity results from several key aspects, presented from most significant:

Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Plate material – mild steel gives the best results. Alloy admixtures decrease magnetic properties and holding force.
Plate texture – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

Precautions when working with neodymium magnets

Crushing risk

Risk of injury: The pulling power is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.

Danger to the youngest

Adult use only. Tiny parts pose a choking risk, causing serious injuries. Keep out of reach of kids and pets.

Shattering risk

Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.

Conscious usage

Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Data carriers

Powerful magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Stay away of min. 10 cm.

Danger to pacemakers

Individuals with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can disrupt the operation of the implant.

Permanent damage

Avoid heat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Machining danger

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

GPS and phone interference

GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.

Nickel coating and allergies

Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, prevent direct skin contact or opt for encased magnets.

Danger! Learn more about risks in the article: Magnet Safety Guide.
