Pulling power drops sharply with every mm of distance. Note that even a microscopic distance (e.g., contamination, varnish, dust) noticeably weakens the grip. Magnetic products hold strongest during direct contact; distance kills the power. Analyze how rapidly the load capacity plummet, when the magnet does not touch tightly to the metal substrate. When planning the mounting, avoid unnecessary gaps.

50 mm	Stal (~0.2)	0.01 kg / 0.03 LBS 14.0 g / 0.1 N

This section defines the theoretical weight limit necessary to initiate the sliding of the magnet vertically against a vertical metal surface (considering typical friction). The holding force depends on the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MP 41x15x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	7.33 kg / 16.16 LBS 7332.0 g / 71.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.89 kg / 10.78 LBS 4888.0 g / 48.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.44 kg / 5.39 LBS 2444.0 g / 24.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	12.22 kg / 26.94 LBS 12220.0 g / 119.9 N

When mounting a magnet on a upright plane (e.g., a car body), it you can count on only about 1/5 of its nominal power. Gravity and a low friction coefficient influence the fact that magnets slide down easier than they pop off the substrate. Planning a vertical fastening? Remember that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will slip down under a noticeably lighter weight. Utilizing a rubberized layer can effectively improve the result.

12 mm	100%	24.44 kg / 53.88 LBS 24440.0 g / 239.8 N

A thin sheet cannot absorb the full magnetic flux, which weakens actual performance of the holder. Should you attach a powerful product to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's power, you require a sufficiently solid piece of metal. The material oversaturation means that on thin elements (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel thickness according to the table below.

Ordinary NdFeB products irreversibly lose power after exceeding the maximum temperature. Protect against heat – high temperature can permanently demagnetize this magnet. With every degree above norm, the magnet's power momentarily lowers. Do not use this magnet in hot environments higher than its working range. Too high temperature will result in permanent loss of magnetic properties.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and sheet combination. Such a system of magnet-to-magnet 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 steel. Exercise caution that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is slightly lower than the attraction, but still large.
*Field value in repulsion mode reaches ~0 Gs at the geometric center of the gap (due to field cancellation).
Attention: Estimates show friction force of dual same magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a large risk to electronics and medical implants. These magnets produce a flux that disrupts operation of sensitive medical devices. Be aware: 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, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during bringing near metal 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 neodymium. Use safety goggles when handling 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.

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

1. Sliding resistance

*Warning: On a vertical wall, the magnet retains only a fraction of its nominal pull.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) drastically reduces the holding force.

3. Heat tolerance

*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) = 0.80

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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. This product with a force of 24.44 kg works great as a cabinet closure, speaker holder, or spacer element in devices.

This is a crucial issue when working with model MP 41x15x10 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle 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. Damage to the protective layer during assembly is the most common cause of rusting. This product is dedicated for indoor use. For outdoor applications, we recommend choosing magnets in hermetic housing or additional protection with varnish.

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. Aesthetic mounting requires selecting the appropriate head size.

It is a magnetic ring with a diameter of 41 mm and thickness 10 mm. The pulling force of this model is an impressive 24.44 kg, which translates to 239.78 N in newtons. The mounting hole diameter is precisely 15 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Strengths and weaknesses of neodymium magnets.

Benefits

Apart from their consistent magnetism, neodymium magnets have these key benefits:

They do not lose power, even during around ten years – the reduction in power is only ~1% (based on measurements),
Neodymium magnets are extremely resistant to magnetic field loss caused by external field sources,
A magnet with a shiny gold surface has an effective appearance,
Magnets exhibit impressive magnetic induction on the active area,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Due to the option of accurate shaping and adaptation to custom requirements, NdFeB magnets can be modeled in a variety of shapes and sizes, which makes them more universal,
Versatile presence in advanced technology sectors – they are commonly used in hard drives, electric drive systems, medical devices, also multitasking production systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Characteristics of disadvantages of neodymium magnets: tips and applications.

At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and 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 suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Furthermore, small components of these products are able to disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Maximum lifting capacity of the magnet – what it depends on?

The load parameter shown represents the maximum value, obtained under optimal environment, namely:

on a block made of mild steel, perfectly concentrating the magnetic flux
whose transverse dimension is min. 10 mm
with an polished contact surface
without any air gap between the magnet and steel
under axial application of breakaway force (90-degree angle)
at temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

Effective lifting capacity impacted by working environment parameters, including (from priority):

Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
Load vector – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
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 type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
Plate texture – ground elements guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
Temperature – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Safe handling of NdFeB magnets

No play value

NdFeB magnets are not toys. Accidental ingestion of several magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires urgent medical intervention.

Medical implants

People with a ICD must keep an safe separation from magnets. The magnetism can stop the functioning of the life-saving device.

Conscious usage

Handle magnets with awareness. Their immense force can shock even experienced users. Be vigilant and respect their force.

Data carriers

Avoid bringing magnets near a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.

Finger safety

Mind your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Power loss in heat

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.

Magnet fragility

Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Avoid contact if allergic

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness appears, cease working with magnets and use protective gear.

Impact on smartphones

GPS units and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.

Machining danger

Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
