Pulling power drops drastically with every subsequent millimeter of gap. Note that even the smallest gap (e.g., contamination, varnish, dust) strongly diminishes the holding power. Magnetic products hold optimally in perfect adhesion; distance drastically cuts the force. Notice how flashily the load capacity fall, when the product does not touch directly to the metal substrate. When calculating the arrangement, discard redundant distances.

This section defines the approximate force needed to cause the shifting of the magnet vertically along a upright steel plate (assuming typical friction coefficient). This value depends on the distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MP 16x8/4x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.83 kg / 1.84 LBS 834.0 g / 8.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.56 kg / 1.23 LBS 556.0 g / 5.5 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.39 kg / 3.06 LBS 1390.0 g / 13.6 N

When placing a holder on a upright surface (e.g., a board), it will only hold barely approx. 20%-30% of its nominal power. Gravitational force and a low friction coefficient cause that products slide down easier than they detach. Want to create a wall mount? Note that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a significantly smaller cargo. Application of an anti-slip coating can drastically raise the stability.

A thin sheet is unable to absorb the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a thin surface, the field will penetrate right through and the pull force will drop sharply. To utilize the maximum of this neodymium's power, you need a suitably thick backing of metal. The saturation effect means that on thin elements (e.g., appliance housings), the product shows lower pull force. We suggest choosing the steel thickness from these parameters.

Standard neodymium magnets irreversibly lose parameters past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly damage this magnet. With increasing heat, the neodymium's force temporarily decreases. Do not use this magnet close to ovens higher than its working range. Exceeding the critical threshold will cause destruction of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products 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 operation. Designing a powerful holder? Utilize two neodymiums instead of one magnet and a steel. Remember that when attracting two neodymiums, the pinch force is massive. The repulsion force is slightly lower than the attraction, but still impressive.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
* Calculations show shear force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to IT equipment as well as pacemakers. These neodymiums produce a flux that prevents correct functioning of digital equipment. Notice: the unseen radiation penetrates the body and housings. Special caution must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - warning
MP 16x8/4x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	26.50 km/h (7.36 m/s)	0.11 J
30 mm	44.74 km/h (12.43 m/s)	0.33 J
50 mm	57.74 km/h (16.04 m/s)	0.55 J
100 mm	81.66 km/h (22.68 m/s)	1.09 J

Magnetic elements are delicate – a collision with steel causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can cause material chips or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when working with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Shear force

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

2. Steel saturation

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

3. Heat tolerance

*For N38 material, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.24

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 ring magnet with a hole MP 16x8/4x3 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. When tightening the screw, you must maintain caution. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force will cause the ring to crack. It's a good idea to use a flexible washer under the screw head, which will cushion the stresses. Remember: cracking during assembly results from material properties, not a product defect.

These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but is not sufficient for rain. Damage to the protective layer during assembly is the most common cause of rusting. This product is dedicated for inside building use. For outdoor applications, we recommend choosing rubberized holders or additional protection with varnish.

A screw or bolt with a thread diameter smaller than 8/4 mm fits this model. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Always check that the screw head is not larger than the outer diameter of the magnet (16 mm), so it doesn't protrude beyond the outline.

It is a magnetic ring with a diameter of 16 mm and thickness 3 mm. The pulling force of this model is an impressive 2.78 kg, which translates to 27.29 N in newtons. The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 8/4 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. In the case of connecting two rings, make sure one is turned the right way. We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Advantages and disadvantages of neodymium magnets.

Pros

Besides their tremendous field intensity, neodymium magnets offer the following advantages:

They retain magnetic properties for around ten years – the drop is just ~1% (based on simulations),
Neodymium magnets are characterized by exceptionally resistant to demagnetization caused by magnetic disturbances,
In other words, due to the shiny layer of silver, the element becomes visually attractive,
Neodymium magnets deliver maximum magnetic induction on a small area, which ensures high operational effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
Possibility of exact forming as well as adjusting to defined conditions,
Key role in innovative solutions – they serve a role in data components, brushless drives, medical devices, also multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
We recommend cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process 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

Pull force analysis

Maximum holding power of the magnet – what it depends on?

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

on a base made of structural steel, perfectly concentrating the magnetic flux
whose transverse dimension is min. 10 mm
characterized by even structure
without any air gap between the magnet and steel
during detachment in a direction perpendicular to the plane
in temp. approx. 20°C

Determinants of lifting force in real conditions

In practice, the actual lifting capacity is determined by several key aspects, listed from the most important:

Gap (betwixt the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal weaken the grip.
Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate lowers the lifting capacity.

Precautions when working with neodymium magnets

Electronic devices

Device Safety: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Adults only

Neodymium magnets are not suitable for play. Swallowing a few magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and necessitates immediate surgery.

Heat sensitivity

Control the heat. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Crushing force

Protect your hands. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!

Threat to navigation

Note: rare earth magnets generate a field that confuses precision electronics. Maintain a separation from your mobile, tablet, and GPS.

Skin irritation risks

Studies show that nickel (standard magnet coating) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands or opt for versions in plastic housing.

Medical implants

Patients with a pacemaker must maintain an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.

Mechanical processing

Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Shattering risk

Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Caution required

Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
