Magnetic force drops drastically with every mm of gap. Keep in mind that even the smallest gap (e.g., dirt, paint, rust) significantly weakens the grip. Magnetic products work most effectively at the point of direct contact; gap drastically cuts the power. See how flashily the load capacity fall, when the magnet does not adhere tightly to the metal substrate. When planning the arrangement, eliminate additional spacers.

The following data shows the approximate weight limit required to initiate the shifting of the magnet downwards along a vertical steel plate (assuming typical friction coefficient). The holding force depends on the distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MW 10x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.67 kg / 1.47 LBS 669.0 g / 6.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.45 kg / 0.98 LBS 446.0 g / 4.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 0.49 LBS 223.0 g / 2.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.12 kg / 2.46 LBS 1115.0 g / 10.9 N

When hanging a magnet on a upright surface (e.g., a board), it will only hold only about 20%-30% of its nominal power. Gravity and a weak degree of grip influence the fact that holders move down easier than they pop off the substrate. Planning a wall mount? Note that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will slip down under a much lighter weight. Using a rubber layer can effectively raise the stability.

12 mm	100%	2.23 kg / 4.92 LBS 2230.0 g / 21.9 N

A thin metal plate is unable to take in the entire magnetic field, which weakens actual performance of the holder. If you mount a strong magnet to a too thin substrate, the magnetism will penetrate right through and the pull force will drop sharply. To achieve 100% of this magnet's power, you need a suitably thick element of metal. The saturation phenomenon means that on sheet metal structures (e.g., car bodies), the product works worse. We advise picking the steel cross-section based on the following data.

Table 5: Working in heat (stability) - resistance threshold

Classic neodymiums irreversibly lose parameters past the thermal threshold. Avoid high temperatures – excessive heat can permanently damage this product. With every degree above norm, the neodymium's power briefly decreases. Do not use this magnet in hot environments higher than its working range. Too high temperature will lead to irreversible degradation of magnetism.

*Important note: Temperature resistance is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) may lose charge permanently sooner than long magnets. Red status in the table signals permanent field degradation for this specific geometry.

Two magnetic products attract each other from a much further distance than a magnet and steel combination. Such a system of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Want to build a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is huge. The repulsion force is slightly lower than the connection force, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
* Estimates show sliding force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field is a serious hazard to IT equipment and medical implants. These neodymiums generate a flux that prevents correct functioning of digital equipment. Notice: the invisible magnetic field acts through matter and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose becomes dangerous. Impact energy can cause material chips or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the magnet. Use safety goggles when playing with powerful specimens.

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 holds only a fraction of its perpendicular strength.

2. Steel thickness impact

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

3. Thermal stability

*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) = 1.21

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.

MW 5x3 / N38 - cylindrical magnet

0.283 ZŁ brutto / pcs

This product is an extremely powerful cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø10x20 mm, guarantees maximum efficiency. The MW 10x20 / N38 model boasts a tolerance of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 2.23 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 21.88 N with a weight of only 11.78 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 10.1 mm) using epoxy glues. To ensure long-term durability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø10x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø10x20 mm, which, at a weight of 11.78 g, makes it an element with impressive magnetic energy density. The value of 21.88 N means that the magnet is capable of holding a weight many times exceeding its own mass of 11.78 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 20 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized diametrically if your project requires it.

Strengths as well as weaknesses of neodymium magnets.

Strengths

Apart from their notable magnetism, neodymium magnets have these key benefits:

They retain attractive force for almost ten years – the drop is just ~1% (in theory),
Magnets effectively resist against demagnetization caused by ambient magnetic noise,
In other words, due to the glossy surface of nickel, the element gains a professional look,
Neodymium magnets ensure maximum magnetic induction on a small surface, which increases force concentration,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of exact creating as well as optimizing to concrete applications,
Universal use in advanced technology sectors – they serve a role in HDD drives, electric drive systems, precision medical tools, also technologically advanced constructions.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons

Problematic aspects of neodymium magnets: tips and applications.

At very strong impacts they can crack, therefore we recommend placing them in special holders. 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 drop of strength (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
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited possibility of creating nuts in the magnet and complicated shapes - preferred is cover - mounting mechanism.
Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can complicate diagnosis medical when they are in the body.
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 it depends on?

The declared magnet strength refers to the limit force, obtained under optimal environment, meaning:

on a plate made of mild steel, optimally conducting the magnetic field
possessing a massiveness of min. 10 mm to ensure full flux closure
with an polished contact surface
with total lack of distance (without impurities)
for force applied at a right angle (in the magnet axis)
at conditions approx. 20°C

Determinants of practical lifting force of a magnet

Holding efficiency is affected by specific conditions, mainly (from priority):

Distance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
Plate thickness – too thin plate does not accept the full field, causing part of the power to be lost to the other side.
Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.

Precautions when working with neodymium magnets

Permanent damage

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Fire warning

Fire warning: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Pinching danger

Risk of injury: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Material brittleness

NdFeB magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets leads to them breaking into shards.

Do not underestimate power

Exercise caution. Neodymium magnets act from a long distance and connect with massive power, often faster than you can react.

This is not a toy

Only for adults. Tiny parts pose a choking risk, causing serious injuries. Keep out of reach of kids and pets.

Keep away from electronics

A strong magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid breaking the sensors.

Sensitization to coating

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.

Magnetic media

Do not bring magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.

Health Danger

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Caution! Learn more about risks in the article: Safety of working with magnets.
