Magnetic force drops drastically with every subsequent millimeter of spacing. Note that every additional insulation layer (e.g., contamination, paint, rust) strongly diminishes the holding power. Magnetic products hold strongest during direct contact; gap nullifies the force. See how flashily the pull force fall, when the magnet does not adhere tightly to the metal substrate. When designing the arrangement, eliminate redundant distances.

The following data shows the estimated shear load needed to start the shifting of the magnet vertically on a vertical steel wall (assuming standard friction coefficient). This parameter depends on the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 30x10x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.67 kg / 5.88 LBS 2667.0 g / 26.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.78 kg / 3.92 LBS 1778.0 g / 17.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.89 kg / 1.96 LBS 889.0 g / 8.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.45 kg / 9.80 LBS 4445.0 g / 43.6 N

When mounting a magnet on a vertical wall (e.g., a car body), it you can count on only about 1/5 of its maximum pull force. Gravity as well as a low friction coefficient mean that products slip easier than they pop off the substrate. Planning a vertical fastening? Consider that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slip down under a significantly smaller weight. Utilizing a rubberized coating can drastically increase the grip.

12 mm	100%	8.89 kg / 19.60 LBS 8890.0 g / 87.2 N

A too thin steel is unable to absorb the entire magnetic field, which weakens actual performance of the magnet. If you mount a strong magnet to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To utilize full efficiency of this magnet's potential, you need a suitably thick element of metal. The saturation effect means that on thin elements (e.g., thin profiles), the product works worse. We advise picking the steel cross-section according to the table below.

Table 5: Thermal stability (stability) - power drop
MPL 30x10x5 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

Classic neodymiums change their properties power after exceeding the maximum temperature. Protect against heat – heat can permanently destroy this product. As the temperature rises, the magnet's power temporarily decreases. Do not use this product close to ovens exceeding its working range. Exceeding the critical threshold will lead to permanent loss of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (pancake types) may lose charge permanently under lower heat stress than long magnets. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a neodymium and metal setup. The connection of two magnets generates a stronger field and a further horizon of operation. Want to build a solid fastener? Apply two magnets instead of one magnet and a steel. Remember that when attracting two neodymiums, the pinch force is massive. The levitation is a bit weaker than the attraction, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Calculations refer to friction force of two matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Safety (HSE) (electronics) - warnings
MPL 30x10x5 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	8.5 cm

A strong magnetic field is a serious hazard to electronic devices and pacemakers. These magnets produce a flux that disrupts operation of digital equipment. Notice: the invisible magnetic field acts through matter and glass. Exceptional care must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - warning
MPL 30x10x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	28.96 km/h (8.04 m/s)	0.36 J
30 mm	49.12 km/h (13.64 m/s)	1.05 J
50 mm	63.39 km/h (17.61 m/s)	1.74 J
100 mm	89.65 km/h (24.90 m/s)	3.49 J

Neodymium magnets are delicate – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Striking energy can cause material chips or dangerous crushing to skin. Always hold the magnet during mounting so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when working with powerful specimens.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds only ~20% of its perpendicular strength.

2. Steel thickness impact

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

3. Thermal stability

*For standard magnets, 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) = 0.35

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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 30x10x5 mm and a weight of 11.25 g, guarantees the highest quality connection. This rectangular block with a force of 87.23 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

The key to success is sliding the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. To separate the MPL 30x10x5 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

They constitute a key element in the production of generators and material handling systems. They work great as fasteners under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 30x10x5 / N38, it is best to use two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 30x10x5 mm, which, at a weight of 11.25 g, makes it an element with high energy density. It is a magnetic block with dimensions 30x10x5 mm and a self-weight of 11.25 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:

They retain magnetic properties for nearly ten years – the drop is just ~1% (based on simulations),
Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external interference,
A magnet with a shiny nickel surface is more attractive,
Magnetic induction on the top side of the magnet is extremely intense,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
In view of the ability of accurate forming and adaptation to specialized solutions, neodymium magnets can be manufactured in a broad palette of shapes and sizes, which expands the range of possible applications,
Versatile presence in advanced technology sectors – they are commonly used in computer drives, motor assemblies, medical devices, and modern systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

What to avoid - cons of neodymium magnets and proposals for their use:

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in realizing nuts and complex forms in magnets, we propose using a housing - magnetic holder.
Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these products can 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

Best holding force of the magnet in ideal parameters – what affects it?

The load parameter shown represents the maximum value, obtained under ideal test conditions, meaning:

with the use of a yoke made of special test steel, ensuring full magnetic saturation
possessing a massiveness of minimum 10 mm to ensure full flux closure
characterized by even structure
without any air gap between the magnet and steel
under vertical force vector (90-degree angle)
at room temperature

Determinants of lifting force in real conditions

During everyday use, the real power results from several key aspects, ranked from most significant:

Distance – existence of foreign body (paint, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Steel type – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and holding force.
Surface quality – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.

Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.

H&S for magnets

Serious injuries

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

Thermal limits

Avoid heat. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).

Material brittleness

Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.

Magnetic media

Equipment safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).

Threat to navigation

An intense magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.

Swallowing risk

NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which poses a severe health hazard and necessitates immediate surgery.

Metal Allergy

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands or opt for coated magnets.

Fire risk

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

Immense force

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.

Life threat

Individuals with a pacemaker should maintain an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.
