Grip strength decreases sharply with every subsequent millimeter of spacing. Remember that even a very thin break (e.g., dirt, paint, rust) strongly weakens the grip. Magnets operate optimally in perfect adhesion; air break drastically cuts the force. See how rapidly the parameters drop, when the magnet does not touch flatly to the metal substrate. When planning the mounting, discard additional spacers.

The following data presents the theoretical holding capacity needed to initiate the slippage of the magnet down on a upright steel plate (considering standard friction coefficient). This parameter varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 20x35 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.87 kg / 6.34 pounds 2874.0 g / 28.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.92 kg / 4.22 pounds 1916.0 g / 18.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.96 kg / 2.11 pounds 958.0 g / 9.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.79 kg / 10.56 pounds 4790.0 g / 47.0 N

When placing a magnet on a upright plane (e.g., a board), it you can count on only about 1/5 of nominal attraction strength. Gravity and a low friction coefficient influence the fact that holders move down faster than they pop off the substrate. Planning a wall mount? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the element will give way down under a significantly smaller weight. Utilizing a rubberized coating can significantly increase the grip.

A thin sheet is incapable of conduct the entire magnetic field, which wastes potential of the holder. If you attach a powerful product to a thin surface, the magnetism will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this magnet's potential, you require a sufficiently solid backing of metal. The saturation phenomenon means that on thin elements (e.g., appliance housings), the product works worse. We advise picking the steel dimension from these parameters.

Standard neodymium magnets irreversibly lose parameters after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently destroy this magnet. With every degree above norm, the magnet's force briefly drops. Do not use this product close to heaters higher than its working range. Ignoring the limit will lead to permanent loss of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (pancake types) risk losing magnetic properties under lower heat stress than long magnets. Red status in the table points to permanent field degradation for this specific geometry.

Two magnetic products interact from a much further distance than a magnet and steel setup. The connection of two magnets generates a stronger field 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. Remember that when attracting two neodymiums, the impact force is massive. The repulsion force is slightly lower than the attraction, but still large.
*Field value in repulsion mode drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Important: Calculations show friction force of two identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Safety (HSE) (electronics) - warnings

Extremely neodym field is a serious hazard to electronic devices as well as pacemakers. These NdFeB products generate a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and plastic. Exceptional care must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MW 20x35 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	11.39 km/h (3.16 m/s)	0.41 J
30 mm	18.85 km/h (5.24 m/s)	1.13 J
50 mm	24.31 km/h (6.75 m/s)	1.88 J
100 mm	34.37 km/h (9.55 m/s)	3.76 J

Neodymium magnets are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or painful pinches to skin. Always hold the magnet during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when playing with large magnets.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

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

1. Shear force

*Caution: On a vertical wall, the magnet retains merely a fraction of its perpendicular strength.

2. Steel saturation

*Thin steel (e.g. computer case) drastically weakens the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.16

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 presented product is a very strong rod magnet, composed of durable NdFeB material, which, at dimensions of Ø20x35 mm, guarantees optimal power. 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. 9.58 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields 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 fastening or actuating element. Thanks to the pull force of 93.97 N with a weight of only 82.47 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, 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 automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets N38 are strong enough for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø20x35), 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 Ø20x35 mm, which, at a weight of 82.47 g, makes it an element with impressive magnetic energy density. The value of 93.97 N means that the magnet is capable of holding a weight many times exceeding its own mass of 82.47 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 20 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.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Pros

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

Their strength is durable, and after around ten years it decreases only by ~1% (theoretically),
They have excellent resistance to magnetism drop due to external magnetic sources,
A magnet with a smooth nickel surface is more attractive,
They feature high magnetic induction at the operating surface, which increases their power,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
In view of the potential of flexible shaping and adaptation to unique solutions, magnetic components can be modeled in a broad palette of shapes and sizes, which makes them more universal,
Versatile presence in modern industrial fields – they are utilized in magnetic memories, electromotive mechanisms, medical devices, also other advanced devices.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Limitations

Cons of neodymium magnets: tips and applications.

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce 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 while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in creating threads and complex forms in magnets, we propose using casing - magnetic mount.
Health risk resulting from small fragments 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 small components of these products can complicate diagnosis medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum magnetic pulling force – what affects it?

The specified lifting capacity refers to the peak performance, measured under optimal environment, meaning:

using a sheet made of mild steel, functioning as a magnetic yoke
whose thickness reaches at least 10 mm
with a plane free of scratches
without any clearance between the magnet and steel
under vertical application of breakaway force (90-degree angle)
in stable room temperature

Lifting capacity in real conditions – factors

Please note that the magnet holding may be lower subject to elements below, in order of importance:

Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Direction of force – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material type – the best choice is pure iron steel. Cast iron may attract less.
Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
Temperature – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the lifting capacity.

H&S for magnets

This is not a toy

Adult use only. Small elements can be swallowed, causing intestinal necrosis. Store out of reach of kids and pets.

Phone sensors

A powerful magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Maintain magnets near a smartphone to avoid breaking the sensors.

Handling rules

Exercise caution. Neodymium magnets act from a distance and connect with massive power, often quicker than you can move away.

Magnets are brittle

Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Physical harm

Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Implant safety

For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.

Sensitization to coating

Certain individuals suffer from a hypersensitivity to nickel, which is the common plating for neodymium magnets. Prolonged contact can result in dermatitis. We recommend use safety gloves.

Fire risk

Powder produced during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Permanent damage

Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.

Safe distance

Avoid bringing magnets close to a wallet, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
