Pulling power drops significantly per each millimeter of distance. Note that even a very thin break (e.g., dirt, paint, veneer) noticeably weakens the grip. Magnets operate most effectively in perfect adhesion; gap nullifies the force. Notice how rapidly the load capacity drop, when the magnet does not adhere tightly to the metal substrate. When planning the arrangement, avoid unnecessary gaps.

The following data shows the estimated force needed to start the sliding of the magnet down against a upright steel wall (considering standard friction coefficient). The holding force is a function of the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MPL 5x5x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.17 kg / 0.38 pounds 174.0 g / 1.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.12 kg / 0.26 pounds 116.0 g / 1.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.06 kg / 0.13 pounds 58.0 g / 0.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.29 kg / 0.64 pounds 290.0 g / 2.8 N

When mounting a holder on a upright plane (e.g., a fridge), it you can count on just approx. 20%-30% of its maximum pull force. Gravitational force as well as a weak degree of grip mean that holders slip easier than they pop off the substrate. Planning a hanger? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a much lighter load. Utilizing a rubberized layer can drastically increase the grip.

A thin metal plate is incapable of absorb the full magnetic flux, which squanders power of the magnet. If you mount a strong magnet to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's power, you require a sufficiently solid element of steel. The saturation effect causes that on sheet metal structures (e.g., car bodies), the magnet holds weaker. We suggest choosing the steel dimension according to the table below.

Table 5: Thermal resistance (material behavior) - resistance threshold
MPL 5x5x1.5 / N38

100 °C	-28.8%	0.41 kg / 0.91 pounds 413.0 g / 4.1 N

Standard neodymium magnets lose parameters past the thermal threshold. Protect against heat – high temperature can permanently demagnetize this product. With every degree above norm, the neodymium's capacity momentarily lowers. Avoid using this magnet near heat sources exceeding its operating temperature limit. Exceeding the critical threshold will lead to destruction of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (pancake types) may lose charge permanently at lower temperatures compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a neodymium and metal setup. The setup of two magnets generates a stronger field and a wider radius of action. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a steel. Remember that when attracting two neodymiums, the impact force is huge. The levitation is slightly lower than the connection force, but still significant.
*Flux density between like poles drops to ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
* Figures apply to sliding force of two same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Neodymium magnets are delicate – a collision with steel risks their cracking. Control the attraction moment – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

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

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 nominal pull.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) severely limits 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) = 0.36

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.

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 5x5x1.5 mm and a weight of 0.28 g, guarantees the highest quality connection. This rectangular block with a force of 5.68 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 0.58 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 wind generators and material handling systems. Thanks to the flat surface and high force (approx. 0.58 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 5x5x1.5 / N38, we recommend utilizing strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. 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. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 5 mm (length), 5 mm (width), and 1.5 mm (thickness). The key parameter here is the holding force amounting to approximately 0.58 kg (force ~5.68 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of rare earth magnets.

Strengths

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

Their strength remains stable, and after approximately ten years it decreases only by ~1% (according to research),
Neodymium magnets are distinguished by extremely resistant to loss of magnetic properties caused by external interference,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnets are characterized by exceptionally strong magnetic induction on the active area,
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...
Thanks to the potential of precise forming and customization to individualized solutions, neodymium magnets can be modeled in a variety of forms and dimensions, which increases their versatility,
Significant place in modern technologies – they serve a role in computer drives, brushless drives, advanced medical instruments, also complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices

Disadvantages

Cons of neodymium magnets: tips and applications.

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 very resistant to heat
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited ability of creating nuts in the magnet and complicated shapes - recommended is casing - magnet mounting.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what it depends on?

Breakaway force was determined for ideal contact conditions, assuming:

on a block made of mild steel, perfectly concentrating the magnetic flux
with a cross-section of at least 10 mm
with an ideally smooth contact surface
without any clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at conditions approx. 20°C

Practical aspects of lifting capacity – factors

It is worth knowing that the magnet holding may be lower depending on elements below, in order of importance:

Space between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Steel grade – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
Surface finish – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

Precautions when working with NdFeB magnets

Threat to electronics

Avoid bringing magnets close to a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.

Danger to pacemakers

People with a heart stimulator should maintain an absolute distance from magnets. The magnetic field can stop the functioning of the implant.

Product not for children

NdFeB magnets are not toys. Swallowing multiple magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates urgent medical intervention.

Magnetic interference

A strong magnetic field disrupts the functioning of compasses in phones and GPS navigation. Do not bring magnets close to a device to avoid damaging the sensors.

Dust explosion hazard

Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.

Nickel allergy

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop handling magnets and use protective gear.

Demagnetization risk

Control the heat. Exposing the magnet to high heat will destroy its properties and pulling force.

Finger safety

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

Powerful field

Handle magnets with awareness. Their huge power can shock even experienced users. Plan your moves and respect their force.

Protective goggles

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets will cause them cracking into small pieces.
