Magnetic force weakens drastically with every subsequent millimeter of gap. Keep in mind that even a microscopic distance (e.g., contamination, paint, rust) noticeably reduces the pull force. Magnets operate most effectively in perfect adhesion; gap nullifies the power. Analyze how flashily the load capacity drop, when the magnet does not touch flatly to the steel surface. When calculating the assembly, eliminate redundant distances.

Table 2: Shear capacity (wall)

50 mm	Stal (~0.2)	0.00 kg / 0.00 LBS 0.0 g / 0.0 N

The table below presents the approximate shear load needed to initiate the sliding of the magnet down against a upright steel wall (considering standard friction coefficient). This value is relative to the separation distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - 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 LBS 537.0 g / 5.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.36 kg / 0.79 LBS 358.0 g / 3.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.18 kg / 0.39 LBS 179.0 g / 1.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.90 kg / 1.97 LBS 895.0 g / 8.8 N

When placing a magnet on a vertical wall (e.g., a fridge), it will maintain barely approx. 1/5 of its nominal power. Gravitational force and a low friction coefficient influence the fact that magnets slip easier than they pull off. Planning a wall mount? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a painted metal, the holder will slip down under a much lighter weight. Using a rubber pad can effectively improve the result.

A thin metal plate is incapable of conduct the entire magnetic field, which wastes potential of the magnet. Should you install a neodymium to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To achieve 100% of this magnet's power, you need a suitably thick element of steel. The saturation effect causes that on sheet metal structures (e.g., car bodies), the magnet shows lower pull force. We suggest choosing the steel dimension according to the table below.

Classic neodymiums change their properties parameters past the thermal threshold. Avoid high temperatures – high temperature can irreversibly damage this product. With every degree above norm, the magnet's force momentarily drops. Refrain from using this magnet in hot environments exceeding its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) may lose charge permanently at lower temperatures than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets produces a massive flux and a further horizon of action. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the collision energy is huge. The levitation is a bit weaker than the connection force, but still large.
*Flux density in repulsion mode is approximately ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Note: Estimates show sliding force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

Table 7: Protective zones (implants) - precautionary measures
MP 10x6x4 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	9.0 cm
Hearing aid	10 Gs (1.0 mT)	7.0 cm
Mechanical watch	20 Gs (2.0 mT)	5.0 cm
Mobile device	40 Gs (4.0 mT)	4.0 cm

Payment card	400 Gs (40.0 mT)	1.5 cm
HDD hard drive	600 Gs (60.0 mT)	1.5 cm

Extremely neodym field poses a serious hazard to electronics as well as pacemakers. These magnets produce a flux that disrupts operation of digital equipment. Remember: the invisible magnetic field acts through matter and plastic. Special caution must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MP 10x6x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	34.94 km/h (9.71 m/s)	0.07 J
30 mm	60.15 km/h (16.71 m/s)	0.21 J
50 mm	77.64 km/h (21.57 m/s)	0.35 J
100 mm	109.80 km/h (30.50 m/s)	0.70 J

Magnetic elements are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a magnet released freely becomes dangerous. Striking energy can cause material chips or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed means shattering of the neodymium. Wear safety glasses when handling 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.

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Caution: On a vertical surface, the magnet holds just a fraction of its perpendicular strength.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Temperature resistance

*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) = 1.44

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.

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. 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 great sensitivity. 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 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. 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.

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 pulling force of this model is an impressive 1.79 kg, which translates to 17.55 N in newtons. The mounting hole diameter is precisely 6 mm.

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

Pros and cons of Nd₂Fe₁₄B magnets.

Pros

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

They do not lose power, even after around ten years – the decrease in strength is only ~1% (based on measurements),
They feature excellent resistance to magnetism drop as a result of opposing magnetic fields,
Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an visually attractive appearance,
Magnets are characterized by maximum magnetic induction on the outer side,
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...
Thanks to flexibility in forming and the capacity to customize to complex applications,
Universal use in modern industrial fields – they are utilized in mass storage devices, electromotive mechanisms, advanced medical instruments, also other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Limitations

Drawbacks and weaknesses of neodymium magnets: tips and applications.

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
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
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in realizing threads and complex forms in magnets, we propose using casing - magnetic holder.
Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small elements 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 force for a neodymium magnet – what affects it?

The load parameter shown represents the maximum value, recorded under laboratory conditions, meaning:

on a base made of mild steel, perfectly concentrating the magnetic flux
whose transverse dimension equals approx. 10 mm
with an ideally smooth contact surface
without any insulating layer between the magnet and steel
for force applied at a right angle (in the magnet axis)
at ambient temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

Please note that the magnet holding may be lower influenced by the following factors, starting with the most relevant:

Distance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Plate material – low-carbon steel attracts best. Higher carbon content lower magnetic permeability and holding force.
Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal weaken the grip.
Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets

Warning for heart patients

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Mechanical processing

Machining of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Heat warning

Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.

No play value

NdFeB magnets are not toys. Eating several magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and requires immediate surgery.

Nickel allergy

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, immediately stop working with magnets and wear gloves.

Keep away from computers

Device Safety: Strong magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Magnetic interference

An intense magnetic field interferes with the operation of compasses in phones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.

Eye protection

Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them breaking into shards.

Safe operation

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

Crushing force

Large magnets can break fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
