Grip strength weakens sharply per each millimeter of gap. Keep in mind that every additional insulation layer (e.g., dirt, varnish, dust) significantly diminishes the holding power. Neodymiums operate optimally during direct contact; distance nullifies the force. See how quickly the load capacity drop, when the magnet does not touch tightly to the metal substrate. When calculating the arrangement, eliminate redundant distances.

This section defines the approximate force necessary to cause the sliding of the magnet vertically along a upright steel wall (considering standard friction). This parameter is a function of the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 15x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.86 kg / 1.90 lbs 861.0 g / 8.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.57 kg / 1.27 lbs 574.0 g / 5.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.29 kg / 0.63 lbs 287.0 g / 2.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.44 kg / 3.16 lbs 1435.0 g / 14.1 N

When mounting a holder on a vertical surface (e.g., a fridge), it will only hold barely about 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient cause that products slip faster than they pull off. Planning a wall mount? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will give way down under a significantly smaller weight. Utilizing a rubberized layer can effectively increase the grip.

A too thin steel is not enough to absorb the entire magnetic field, which wastes potential of the magnet. If you install a neodymium to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To achieve the maximum of this neodymium's potential, you require a sufficiently solid backing of steel. The saturation phenomenon means that on thin elements (e.g., car bodies), the holder works worse. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products lose parameters above the temperature limit. Protect against heat – excessive heat can irreversibly demagnetize this magnet. With every degree above norm, the magnet's power temporarily drops. Refrain from using this magnet close to ovens exceeding its working range. Ignoring the limit will lead to irreversible degradation of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and steel setup. The connection of magnet-to-magnet produces a massive flux and a further horizon of action. Planning to create a solid fastener? Apply two magnets instead of one magnet 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 impressive.
*Flux density between like poles drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
Important: Calculations demonstrate sliding force of two identical magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field is a serious hazard to electronic devices as well as medical implants. These NdFeB products generate a field that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field acts through matter and housings. Special caution must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, remotes, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - warning

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	27.62 km/h (7.67 m/s)	0.12 J

NdFeB products are prone to chipping – a violent impact against metal risks their cracking. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Impact energy can trigger coating fragments or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the neodymium. Use safety goggles when working with large magnets.

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

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

1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds merely ~20% of its nominal pull.

2. Steel thickness impact

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

3. Temperature resistance

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.29

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.

This product is an extremely powerful cylinder magnet, made from durable NdFeB material, which, at dimensions of Ø15x3 mm, guarantees the highest energy density. This specific item features high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 2.87 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 28.14 N with a weight of only 3.98 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 long-term durability in industry, anaerobic resins 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 even stronger magnets in the same volume (Ø15x3), 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 Ø15x3 mm, which, at a weight of 3.98 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 2.87 kg (force ~28.14 N), which, with such defined dimensions, proves the high power of the NdFeB material. 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. 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.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Strengths

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

They do not lose power, even after approximately ten years – the decrease in lifting capacity is only ~1% (according to tests),
They show high resistance to demagnetization induced by external disturbances,
A magnet with a metallic silver surface is more attractive,
Neodymium magnets create maximum magnetic induction on a small surface, which increases force concentration,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to flexibility in constructing and the ability to modify to unusual requirements,
Significant place in modern industrial fields – they are utilized in magnetic memories, electric drive systems, advanced medical instruments, and modern systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Characteristics of disadvantages of neodymium magnets: application proposals

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Limited possibility of creating nuts in the magnet and complicated forms - recommended is a housing - magnetic holder.
Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these products are able to complicate diagnosis medical after entering the body.
With budget limitations the cost of neodymium magnets is economically unviable,

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what contributes to it?

The load parameter shown refers to the peak performance, recorded under laboratory conditions, namely:

on a block made of structural steel, effectively closing the magnetic flux
possessing a massiveness of minimum 10 mm to ensure full flux closure
with an polished touching surface
with direct contact (without paint)
during detachment in a direction perpendicular to the mounting surface
in stable room temperature

Determinants of practical lifting force of a magnet

During everyday use, the actual holding force is determined by many variables, presented from crucial:

Distance – existence of foreign body (rust, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
Steel thickness – too thin sheet causes magnetic saturation, causing part of the flux to be lost to the other side.
Metal type – different alloys reacts the same. High carbon content weaken the attraction effect.
Smoothness – 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. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Warnings

Skin irritation risks

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness appears, cease handling magnets and wear gloves.

Pacemakers

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Demagnetization risk

Watch the temperature. Exposing the magnet to high heat will permanently weaken its properties and strength.

Pinching danger

Large magnets can crush fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.

Protective goggles

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

Product not for children

Absolutely store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are life-threatening.

Do not drill into magnets

Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.

Immense force

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.

Magnetic interference

A strong magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Keep magnets near a smartphone to prevent damaging the sensors.

Electronic devices

Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
