Pulling power drops drastically per each millimeter of distance. Note that even a very thin break (e.g., contamination, varnish, dust) significantly diminishes the holding power. Neodymiums operate optimally during direct contact; gap kills the power. Notice how rapidly the load capacity plummet, when the magnet does not touch tightly to the metal substrate. When planning the arrangement, discard additional spacers.

The table below defines the estimated weight limit needed to cause the slippage of the magnet vertically along a upright steel wall (considering typical friction). The holding force is relative to the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MPL 30x15x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.63 kg / 633.0 g 6.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.42 kg / 422.0 g 4.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.21 kg / 211.0 g 2.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.06 kg / 1055.0 g 10.3 N

When mounting a holder on a upright wall (e.g., a car body), it you can count on only approx. 1/5 of its maximum pull force. Gravitational force and a weak degree of grip mean that products move down faster than they pull off. Want to create a hanger? Remember that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will slide down under a significantly smaller cargo. Application of an anti-slip coating can effectively increase the grip.

Table 4: Material efficiency (substrate influence) - power losses
MPL 30x15x2 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.21 kg / 211.0 g 2.1 N
1 mm	25%	0.53 kg / 527.5 g 5.2 N
2 mm	50%	1.06 kg / 1055.0 g 10.3 N
5 mm	100%	2.11 kg / 2110.0 g 20.7 N
10 mm	100%	2.11 kg / 2110.0 g 20.7 N

A thin sheet is not enough to absorb the entire magnetic field, which wastes potential of the holder. If you attach a powerful product to a too thin substrate, the magnetism will pass right through and the holding will be smaller. To achieve full efficiency of this magnet's power, you need a suitably thick piece of metal. The material oversaturation means that on sheet metal structures (e.g., car bodies), the magnet shows lower pull force. We suggest choosing the steel cross-section according to the table below.

Table 5: Thermal stability (stability) - thermal limit
MPL 30x15x2 / N38

100 °C	-28.8%	1.50 kg / 1502.3 g 14.7 N

Standard neodymium magnets lose strength after exceeding the maximum temperature. Protect against heat – excessive heat can irreversibly damage this product. With increasing heat, the neodymium's power temporarily decreases. Do not use this magnet close to ovens higher than its operating temperature limit. Exceeding the critical threshold will lead to destruction of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) may lose charge permanently at lower temperatures compared to rod magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal combination. Such a system of two magnets creates a more powerful interaction and a larger range of performance. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the impact force is massive. The repulsion force is a bit weaker than the connection force, but still impressive.
*Flux density between like poles is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).

Extremely neodym field poses a large risk to electronic devices and medical implants. These neodymiums produce a flux that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and housings. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are prone to chipping – a violent impact against metal risks their cracking. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Impact energy can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when playing with powerful specimens.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Caution: On a vertical wall, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

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

3. Thermal stability

*For N38 grade, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.13

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.

Component MPL 30x15x2 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 2.11 kg), this product is available off-the-shelf from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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. Watch your fingers! Magnets with a force of 2.11 kg can pinch very hard and cause hematomas. 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. Thanks to the flat surface and high force (approx. 2.11 kg), they are ideal as closers in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. In practice, this means that this magnet has the greatest attraction force on its main planes (30x15 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 30x15x2 mm, which, at a weight of 6.75 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 2.11 kg (force ~20.74 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Advantages

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

They have stable power, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
They retain their magnetic properties even under close interference source,
A magnet with a smooth gold surface has an effective appearance,
Neodymium magnets create maximum magnetic induction on a contact point, which allows for strong attraction,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of custom modeling as well as optimizing to atypical needs,
Fundamental importance in modern industrial fields – they find application in data components, electric motors, medical devices, as well as multitasking production systems.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Weaknesses

Cons of neodymium magnets: tips and applications.

At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in realizing threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
Health risk related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Maximum holding power of the magnet – what affects it?

Magnet power was determined for optimal configuration, taking into account:

on a block made of mild steel, effectively closing the magnetic flux
possessing a thickness of minimum 10 mm to avoid saturation
with a surface perfectly flat
with direct contact (without impurities)
for force acting at a right angle (in the magnet axis)
at conditions approx. 20°C

Practical lifting capacity: influencing factors

It is worth knowing that the working load may be lower depending on elements below, starting with the most relevant:

Clearance – existence of foreign body (paint, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet and the plate lowers the load capacity.

Precautions when working with neodymium magnets

Medical implants

Patients with a heart stimulator have to maintain an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.

Product not for children

Strictly store magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are tragic.

Metal Allergy

Certain individuals experience a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to dermatitis. We strongly advise wear protective gloves.

Protective goggles

Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Electronic hazard

Device Safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, mechanical watches).

Powerful field

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

Power loss in heat

Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.

Impact on smartphones

Navigation devices and mobile phones are highly sensitive to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.

Flammability

Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.

Crushing force

Big blocks can crush fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
