Pulling power decreases drastically with every subsequent millimeter of spacing. Note that even a very thin break (e.g., dirt, varnish, veneer) significantly weakens the grip. Magnetic products work most effectively at the point of direct contact; gap kills the force. Observe how flashily the pull force drop, when the product does not touch directly to the steel surface. When designing the assembly, discard redundant distances.

The following data calculates the theoretical holding capacity needed to start the downward movement of the magnet vertically against a vertical steel wall (assuming standard friction coefficient). This parameter is relative to the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 8x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.55 kg / 1.22 lbs 552.0 g / 5.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.37 kg / 0.81 lbs 368.0 g / 3.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.18 kg / 0.41 lbs 184.0 g / 1.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.92 kg / 2.03 lbs 920.0 g / 9.0 N

When hanging a magnet on a vertical surface (e.g., a fridge), it will maintain just approx. 20%-30% of its nominal power. Gravity as well as a weak degree of grip cause that holders slide down easier than they pull off. Planning a vertical fastening? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will give way down under a significantly smaller weight. Utilizing a rubberized pad can effectively improve the result.

12 mm	100%	1.84 kg / 4.06 lbs 1840.0 g / 18.1 N

A thin sheet is incapable of absorb the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a too thin substrate, the field will pass right through and the pull force will drop sharply. To achieve 100% of this magnet's potential, you require a sufficiently solid piece of metal. The saturation effect means that on thin elements (e.g., car bodies), the holder works worse. We recommend selecting the steel thickness according to the table below.

Ordinary NdFeB products change their properties strength after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly demagnetize this product. With every degree above norm, the magnet's power briefly decreases. Avoid using this product close to ovens higher than its operating temperature limit. Ignoring the limit will result in permanent loss of magnetism.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (pancake types) are more susceptible to demagnetization sooner than long magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnets interact from a significantly greater distance than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the collision energy is massive. The repulsion force is a bit weaker than the connection force, but still large.
*Flux density between like poles drops to ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Note: Figures apply to sliding force of dual identical magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to IT equipment as well as pacemakers. These magnets generate a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field acts through matter and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Start from (mm)	Speed (km/h)	Energy (J)

NdFeB products are delicate – a collision with steel causes immediate chipping. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or painful pinches to fingers. Always hold the magnet during mounting so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with large magnets.

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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Caution: On a vertical wall, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Power loss vs temp

*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) = 1.00

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 presented product is an extremely powerful cylindrical magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø8x10 mm, guarantees optimal power. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 1.84 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 18.00 N with a weight of only 3.77 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø8x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø8x10 mm, which, at a weight of 3.77 g, makes it an element with impressive magnetic energy density. The value of 18.00 N means that the magnet is capable of holding a weight many times exceeding its own mass of 3.77 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 8 mm. Such an arrangement is standard 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.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Strengths

Besides their high retention, neodymium magnets are valued for these benefits:

They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
Magnets very well protect themselves against demagnetization caused by ambient magnetic noise,
A magnet with a metallic nickel surface has better aesthetics,
Magnetic induction on the surface of the magnet is maximum,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Thanks to versatility in designing and the capacity to customize to specific needs,
Wide application in modern industrial fields – they are used in hard drives, electromotive mechanisms, advanced medical instruments, and complex engineering applications.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

Characteristics of disadvantages of neodymium magnets and proposals for their use:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing nuts and complex forms in magnets, we propose using cover - magnetic mount.
Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
With mass production the cost of neodymium magnets can be a barrier,

Holding force characteristics

Magnetic strength at its maximum – what affects it?

Magnet power was determined for ideal contact conditions, taking into account:

on a base made of structural steel, perfectly concentrating the magnetic field
whose transverse dimension reaches at least 10 mm
with a surface free of scratches
without any clearance between the magnet and steel
for force applied at a right angle (in the magnet axis)
at conditions approx. 20°C

What influences lifting capacity in practice

During everyday use, the actual lifting capacity depends on many variables, ranked from the most important:

Distance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Load vector – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
Steel type – mild steel attracts best. Alloy admixtures lower magnetic properties and holding force.
Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate reduces the load capacity.

H&S for magnets

Maximum temperature

Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and pulling force.

Fire warning

Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.

Danger to pacemakers

Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Bone fractures

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

Electronic devices

Do not bring magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.

Powerful field

Use magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and respect their force.

Risk of cracking

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Choking Hazard

Adult use only. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from children and animals.

Avoid contact if allergic

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, prevent touching magnets with bare hands and select versions in plastic housing.

Compass and GPS

Navigation devices and mobile phones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the internal compass in your phone.

Caution! More info about risks in the article: Safety of working with magnets.
