Pulling power weakens sharply per each millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, varnish, rust) significantly weakens the grip. Neodymiums work strongest at the point of direct contact; gap kills the power. Analyze how rapidly the load capacity fall, when the product does not touch directly to the steel surface. When planning the mounting, discard redundant distances.

This section presents the estimated shear load necessary to initiate the shifting of the magnet vertically on a vertical metal surface (considering typical friction coefficient). This value is relative to the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MP 10x6x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.54 kg / 1.18 pounds 537.0 g / 5.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.36 kg / 0.79 pounds 358.0 g / 3.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.18 kg / 0.39 pounds 179.0 g / 1.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.90 kg / 1.97 pounds 895.0 g / 8.8 N

When mounting a magnet on a upright plane (e.g., a car body), it will maintain just about 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that magnets slide down faster than they pull off. Planning a vertical fastening? Note that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the element will give way down under a significantly smaller weight. Application of an anti-slip coating can effectively raise the stability.

12 mm	100%	1.79 kg / 3.95 pounds 1790.0 g / 17.6 N

A thin sheet is incapable of conduct the full magnetic flux, which squanders power of the holder. If you install a neodymium to a too thin substrate, the field will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's potential, you need a suitably thick backing of steel. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the holder works worse. We recommend selecting the steel dimension according to the table below.

Standard neodymium magnets change their properties power past the thermal threshold. Protect against heat – heat can permanently demagnetize this product. As the temperature rises, the neodymium's force momentarily drops. Refrain from using this magnet in hot environments exceeding its safe range. Ignoring the limit will cause destruction of magnetism.

*Engineering note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) risk losing magnetic properties sooner than taller cylinders. Red status in the table points to permanent field degradation for this particular item.

Two magnets attract each other from a wider radius than a neodymium and metal combination. The setup of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Planning to create a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when bringing together two magnets, the collision energy is massive. The repulsion force is marginally weaker than the attraction, but still impressive.
*The magnetic induction between like poles is approximately ~0 Gs in the exact middle between the magnets (due to field cancellation).
Note: Figures refer to sliding force of two matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a real danger to electronic devices and medical implants. These NdFeB products generate a flux that destroys function of digital equipment. Remember: the invisible magnetic field acts through matter and plastic. Exceptional care must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can cause material chips or injury to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the neodymium. Use safety goggles when handling with large magnets.

Corrosion warning: 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. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds only a fraction of its max power.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Heat tolerance

*For N38 material, 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) = 1.44

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 quick installation to wood, wall, plastic, or metal. This product with a force of 1.79 kg works great as a door latch, speaker holder, or mounting element in devices.

This is a crucial issue when working with model MP 10x6x4 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. When tightening the screw, you must maintain great sensitivity. We recommend tightening manually with a screwdriver, not an impact driver, because too much pressure will cause the ring to crack. It's a good idea to use a rubber spacer under the screw head, which will cushion the stresses. 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. If you must use it outside, paint it with anti-corrosion paint after mounting.

A screw or bolt with a thread diameter smaller than 6 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 (10 mm), so it doesn't protrude beyond the outline.

It is a magnetic ring with a diameter of 10 mm and thickness 4 mm. The key parameter here is the lifting capacity amounting to approximately 1.79 kg (force ~17.55 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 6 mm.

The poles are located on the planes with holes, not on the sides of the ring. 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.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Pros

In addition to their pulling strength, neodymium magnets provide the following advantages:

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
They are extremely resistant to demagnetization induced by external field influence,
Thanks to the shimmering finish, the surface of nickel, gold-plated, or silver gives an professional appearance,
Magnetic induction on the surface of the magnet remains exceptional,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to the possibility of flexible molding and adaptation to custom projects, neodymium magnets can be created in a broad palette of forms and dimensions, which expands the range of possible applications,
Huge importance in modern technologies – they are utilized in mass storage devices, motor assemblies, medical devices, also technologically advanced constructions.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Cons

Drawbacks and weaknesses of neodymium magnets and proposals for their use:

Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
Neodymium magnets decrease 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
They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complicated shapes in magnets, we propose using casing - magnetic mechanism.
Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Additionally, small components of these products can complicate diagnosis medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Holding force characteristics

Highest magnetic holding force – what it depends on?

Information about lifting capacity was defined for optimal configuration, taking into account:

using a plate made of mild steel, serving as a circuit closing element
whose transverse dimension equals approx. 10 mm
with a plane free of scratches
without the slightest clearance between the magnet and steel
under axial application of breakaway force (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Determinants of practical lifting force of a magnet

Effective lifting capacity is influenced by specific conditions, mainly (from most important):

Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Direction of force – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
Plate thickness – insufficiently thick plate does not accept the full field, causing part of the power to be lost to the other side.
Material composition – not every steel attracts identically. High carbon content worsen the attraction effect.
Plate texture – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Precautions when working with NdFeB magnets

Physical harm

Big blocks can crush fingers instantly. Never put your hand betwixt two attracting surfaces.

Life threat

Patients with a pacemaker should keep an safe separation from magnets. The magnetic field can interfere with the functioning of the life-saving device.

Mechanical processing

Powder generated during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Caution required

Be careful. Neodymium magnets attract from a long distance and snap with huge force, often faster than you can react.

Adults only

Always store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are fatal.

Keep away from electronics

Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.

Sensitization to coating

Studies show that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or choose encased magnets.

Shattering risk

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets will cause them breaking into shards.

Protect data

Equipment safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).

Do not overheat magnets

Avoid heat. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
