Magnetic force drops significantly with every mm of gap. Note that even a very thin break (e.g., dirt, varnish, rust) noticeably diminishes the holding power. Neodymiums operate strongest in perfect adhesion; air break nullifies the power. Observe how flashily the parameters plummet, when the product does not touch flatly to the metal substrate. When designing the mounting, avoid redundant distances.

The table below calculates the approximate force necessary to initiate the shifting of the magnet down on a vertical metal surface (considering typical friction coefficient). This parameter depends on the air gap between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 10x8 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.01 kg / 2.24 LBS 1014.0 g / 9.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.68 kg / 1.49 LBS 676.0 g / 6.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.34 kg / 0.75 LBS 338.0 g / 3.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.69 kg / 3.73 LBS 1690.0 g / 16.6 N

When mounting a magnet on a upright wall (e.g., a car body), it will only hold only approx. 20%-30% of its nominal power. Gravitational force as well as a low friction coefficient mean that magnets move down faster than they pull off. Planning a hanger? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a significantly smaller cargo. Utilizing a rubberized layer can effectively raise the stability.

A thin sheet is incapable of conduct the entire magnetic field, which squanders power of the holder. If you mount a strong magnet to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To utilize full efficiency of this neodymium's power, you require a sufficiently solid element of steel. The saturation phenomenon causes that on thin elements (e.g., appliance housings), the holder holds weaker. We advise picking the steel cross-section based on the following data.

Classic neodymiums irreversibly lose strength above the temperature limit. Avoid high temperatures – heat can permanently demagnetize this magnet. With increasing heat, the magnet's power briefly lowers. Do not use this product in hot environments exceeding its working range. Too high temperature will result in irreversible degradation of magnetic properties.

*Engineering note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning 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. Such a system of two magnets produces a massive flux and a further horizon of performance. Planning to create a powerful holder? Apply two magnets instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the impact force is huge. The repulsion force is slightly lower than the attraction, but still large.
*Field value for N-N configuration reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Results show friction force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to electronic devices as well as medical implants. These neodymiums produce a flux that destroys function of sensitive medical devices. Be aware: the unseen radiation acts through matter and plastic. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a strong collision with metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Use safety goggles when handling with large magnets.

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Warning: On a vertical surface, the magnet holds just approx. 20-30% of its nominal pull.

2. Steel saturation

*Thin steel (e.g. computer case) severely limits the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.79

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 exceptionally strong rod magnet, made from modern NdFeB material, which, at dimensions of Ø10x8 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 3.38 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building generators, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 33.16 N with a weight of only 4.71 g, this rod 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 chipping the coating of this precision component. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are suitable for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø10x8), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø10x8 mm, which, at a weight of 4.71 g, makes it an element with high magnetic energy density. The value of 33.16 N means that the magnet is capable of holding a weight many times exceeding its own mass of 4.71 g. The product has a [NiCuNi] coating, which secures it 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 10 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.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Pros

Besides their immense strength, neodymium magnets offer the following advantages:

They do not lose power, even during nearly ten years – the drop in power is only ~1% (based on measurements),
Magnets perfectly defend themselves against loss of magnetization caused by external fields,
Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an professional appearance,
Magnets have exceptionally strong magnetic induction on the active area,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Possibility of exact creating and optimizing to complex conditions,
Huge importance in high-tech industry – they are commonly used in hard drives, electric drive systems, diagnostic systems, and other advanced devices.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Limitations

Problematic aspects of neodymium magnets and ways of using them

To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as 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
They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited ability of creating threads in the magnet and complicated shapes - preferred is cover - magnetic holder.
Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting force for a neodymium magnet – what contributes to it?

The force parameter is a theoretical maximum value conducted under specific, ideal conditions:

with the contact of a yoke made of special test steel, ensuring full magnetic saturation
with a cross-section no less than 10 mm
with a surface cleaned and smooth
without the slightest clearance between the magnet and steel
under perpendicular force direction (90-degree angle)
at standard ambient temperature

Impact of factors on magnetic holding capacity in practice

In practice, the actual holding force is determined by a number of factors, listed from the most important:

Gap (betwixt the magnet and the metal), since even a very small distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be escaped into the air.
Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic permeability and holding force.
Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.

Safety rules for work with neodymium magnets

Medical implants

Individuals with a heart stimulator must maintain an large gap from magnets. The magnetism can disrupt the operation of the implant.

GPS and phone interference

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

Safe operation

Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Do not give to children

Only for adults. Small elements pose a choking risk, leading to intestinal necrosis. Store away from kids and pets.

Nickel allergy

Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, refrain from direct skin contact and select encased magnets.

Material brittleness

Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Thermal limits

Avoid heat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).

Threat to electronics

Avoid bringing magnets close to a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.

Dust explosion hazard

Machining of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Finger safety

Pinching hazard: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Use thick gloves.

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