Grip strength drops sharply with every mm of gap. Keep in mind that every additional insulation layer (e.g., contamination, paint, veneer) noticeably weakens the grip. Neodymiums operate optimally in perfect adhesion; gap weakens the force. Observe how rapidly the parameters fall, when the magnet does not touch tightly to the metal substrate. When planning the assembly, eliminate unnecessary gaps.

The following data defines the theoretical holding capacity needed to initiate the shifting of the magnet down on a vertical metal surface (considering typical friction coefficient). This value varies with the distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 15x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.27 kg / 2.79 pounds 1266.0 g / 12.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.84 kg / 1.86 pounds 844.0 g / 8.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.42 kg / 0.93 pounds 422.0 g / 4.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.11 kg / 4.65 pounds 2110.0 g / 20.7 N

When mounting a holder on a upright surface (e.g., a car body), it you can count on barely approx. 1/5 of its nominal power. Gravitational force and a weak degree of grip mean that products slip easier than they pull off. Planning a hanger? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a noticeably lighter weight. Using a rubber pad can effectively improve the result.

12 mm	100%	4.22 kg / 9.30 pounds 4220.0 g / 41.4 N

A too thin steel is not enough to absorb the full magnetic flux, which squanders power of the magnet. If you mount a strong magnet to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this magnet's potential, you require a sufficiently solid backing of metal. The saturation effect causes that on thin elements (e.g., car bodies), the product works worse. We recommend selecting the steel thickness according to the table below.

Standard neodymium magnets change their properties strength after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly demagnetize this magnet. As the temperature rises, the magnet's force briefly drops. Refrain from using this magnet near heat sources exceeding its operating temperature limit. Ignoring the limit will result in destruction of magnetic properties.

*Important note: Temperature resistance is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) may lose charge permanently sooner compared to rod magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal setup. The connection of two magnets generates a stronger field 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 bringing together two magnets, the impact force is massive. The repulsion force is marginally weaker than the connection force, but still large.
*Flux density for N-N configuration drops to ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
* Figures refer to sliding force of dual same neodymium magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field is a real danger to electronics as well as medical implants. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Remember: the unseen radiation penetrates the body and plastic. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (kinetic energy) - collision effects
MW 15x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	28.99 km/h (8.05 m/s)	0.17 J

100 mm	89.99 km/h (25.00 m/s)	1.66 J

Neodymium magnets are very brittle – a violent impact against metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Impact energy can cause material chips or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the magnet. Use safety goggles when handling with powerful specimens.

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Sliding resistance

*Warning: On a vertical surface, the magnet holds merely approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) significantly weakens the holding force.

3. Heat tolerance

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.37

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 incredibly powerful rod magnet, composed of advanced NdFeB material, which, at dimensions of Ø15x4 mm, guarantees the highest energy density. The MW 15x4 / N38 component boasts high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 4.22 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 41.38 N with a weight of only 5.3 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

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 precision component. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are suitable for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø15x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 15 mm and height 4 mm. The value of 41.38 N means that the magnet is capable of holding a weight many times exceeding its own mass of 5.3 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, 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 15 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 neodymium magnets.

Pros

Besides their exceptional pulling force, neodymium magnets offer the following advantages:

They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
They possess excellent resistance to magnetism drop due to opposing magnetic fields,
A magnet with a smooth silver surface has an effective appearance,
They feature high magnetic induction at the operating surface, which affects their effectiveness,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Thanks to the option of flexible forming and adaptation to custom projects, magnetic components can be created in a wide range of forms and dimensions, which expands the range of possible applications,
Huge importance in advanced technology sectors – they are commonly used in data components, electric drive systems, medical devices, and modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Cons

Drawbacks and weaknesses of neodymium magnets and ways of using them

At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Limited possibility of making threads in the magnet and complicated shapes - preferred is casing - magnetic holder.
Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, small components of these devices can complicate diagnosis medical in case of swallowing.
Due to complex production process, their price exceeds standard values,

Pull force analysis

Detachment force of the magnet in optimal conditions – what contributes to it?

The specified lifting capacity refers to the limit force, measured under optimal environment, specifically:

on a plate made of mild steel, effectively closing the magnetic field
possessing a massiveness of min. 10 mm to ensure full flux closure
with a plane free of scratches
under conditions of ideal adhesion (metal-to-metal)
for force acting at a right angle (in the magnet axis)
in neutral thermal conditions

Magnet lifting force in use – key factors

Effective lifting capacity is affected by specific conditions, such as (from most important):

Air gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
Angle of force application – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
Surface finish – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet and the plate lowers the load capacity.

H&S for magnets

Machining danger

Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Cards and drives

Do not bring magnets close to a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.

Pinching danger

Large magnets can crush fingers instantly. Never put your hand betwixt two strong magnets.

Allergic reactions

It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or opt for coated magnets.

Handling guide

Use magnets with awareness. Their powerful strength can surprise even experienced users. Stay alert and respect their power.

Medical interference

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.

Product not for children

NdFeB magnets are not toys. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and necessitates immediate surgery.

Eye protection

Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Heat warning

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.

GPS Danger

GPS units and smartphones are highly susceptible to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.
