Pulling power decreases significantly per each millimeter of distance. Keep in mind that even a microscopic distance (e.g., contamination, varnish, veneer) strongly reduces the pull force. Neodymiums hold most effectively during direct contact; distance kills the power. Notice how rapidly the pull force drop, when the magnet does not touch flatly to the steel surface. When calculating the mounting, eliminate redundant distances.

The table below defines the estimated shear load necessary to initiate the sliding of the magnet downwards on a upright metal surface (considering standard friction coefficient). This parameter depends on the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MP 20x10x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.56 kg / 3.44 LBS 1560.0 g / 15.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.04 kg / 2.29 LBS 1040.0 g / 10.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.52 kg / 1.15 LBS 520.0 g / 5.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.60 kg / 5.73 LBS 2600.0 g / 25.5 N

When placing a magnet on a upright plane (e.g., a board), it will only hold just approx. 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that holders move down faster than they pop off the substrate. Want to create a hanger? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the element will slip down under a noticeably lighter load. Using a rubber layer can drastically increase the grip.

A thin sheet cannot take in the entire magnetic field, which wastes potential of the magnet. Should you attach a powerful product to a too thin substrate, the field will pass right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's power, you need a suitably thick piece of metal. The saturation phenomenon means that on thin elements (e.g., appliance housings), the product holds weaker. We advise picking the steel dimension based on the following data.

Classic neodymiums change their properties power after exceeding the maximum temperature. Avoid high temperatures – heat can permanently demagnetize this magnet. With increasing heat, the magnet's force briefly drops. Avoid using this magnet near heat sources exceeding its working range. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) are more susceptible to demagnetization sooner than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and sheet setup. The connection of magnet-to-magnet produces a massive flux and a wider radius of operation. Planning to create a powerful holder? Apply two magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the collision energy is massive. The levitation is a bit weaker than the attraction, but still significant.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Attention: Figures demonstrate friction force of two identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a real danger to electronics as well as pacemakers. These NdFeB products produce a field that disrupts operation of digital equipment. Remember: the invisible magnetic field penetrates the body and plastic. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are prone to chipping – a strong collision with metal risks their cracking. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can cause material chips or injury to fingers. Always hold the magnet during mounting so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when working with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Sliding resistance

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

2. Plate thickness effect

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

3. Temperature resistance

*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) = 1.13

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 ring magnet with a hole MP 20x10x5 / N38 is created for permanent mounting, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This is a crucial issue when working with model MP 20x10x5 / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable and inelastic. One turn too many can destroy the magnet, so do it slowly. The flat screw head should evenly press the magnet. Remember: cracking during assembly results from material properties, not a product defect.

Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. In the place of the mounting hole, the coating is thinner and easily scratched when tightening the screw, which will become a corrosion focus. If you must use it outside, paint it with anti-corrosion paint after mounting.

The inner hole diameter determines the maximum size of the mounting element. If the magnet does not have a chamfer (cone), we recommend using a screw with a flat or cylindrical head, or possibly using a washer. Always check that the screw head is not larger than the outer diameter of the magnet (20 mm), so it doesn't protrude beyond the outline.

This model is characterized by dimensions Ø20x5 mm and a weight of 8.84 g. The key parameter here is the holding force amounting to approximately 5.20 kg (force ~50.97 N). The mounting hole diameter is precisely 10 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. When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Strengths

Besides their durability, neodymium magnets are valued for these benefits:

Their magnetic field is maintained, and after around 10 years it decreases only by ~1% (theoretically),
Magnets very well resist against demagnetization caused by foreign field sources,
A magnet with a metallic silver surface has an effective appearance,
The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Thanks to flexibility in forming and the capacity to adapt to specific needs,
Fundamental importance in future technologies – they are used in computer drives, electric motors, medical devices, and other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Drawbacks and weaknesses of neodymium magnets: application proposals

At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited possibility of creating threads in the magnet and complex shapes - preferred is casing - mounting mechanism.
Health risk to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Furthermore, small components of these magnets are able to complicate diagnosis medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what it depends on?

The specified lifting capacity concerns the maximum value, recorded under laboratory conditions, meaning:

on a block made of mild steel, optimally conducting the magnetic field
whose transverse dimension is min. 10 mm
characterized by lack of roughness
with total lack of distance (without impurities)
under axial application of breakaway force (90-degree angle)
at temperature approx. 20 degrees Celsius

Determinants of practical lifting force of a magnet

Please note that the application force may be lower influenced by the following factors, in order of importance:

Distance (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
Plate texture – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Safe handling of NdFeB magnets

Safe distance

Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Implant safety

For implant holders: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.

Do not give to children

Always store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are tragic.

Conscious usage

Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Sensitization to coating

A percentage of the population experience a sensitization to nickel, which is the standard coating for neodymium magnets. Frequent touching might lead to a rash. We recommend wear safety gloves.

Dust explosion hazard

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

Crushing risk

Large magnets can smash fingers instantly. Do not put your hand between two attracting surfaces.

Operating temperature

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

Impact on smartphones

GPS units and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.

Fragile material

NdFeB magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them breaking into shards.
