Grip strength drops drastically per each millimeter of spacing. Remember that even a very thin break (e.g., contamination, varnish, veneer) strongly diminishes the holding power. Neodymiums operate most effectively during direct contact; gap nullifies the power. Observe how quickly the pull force drop, when the magnet does not adhere flatly to the steel surface. When planning the assembly, discard unnecessary gaps.

This section presents the approximate holding capacity needed to initiate the downward movement of the magnet downwards against a vertical steel plate (assuming standard friction coefficient). This parameter depends on the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 3x3x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.11 kg / 0.24 pounds 108.0 g / 1.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.07 kg / 0.16 pounds 72.0 g / 0.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.08 pounds 36.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.18 kg / 0.40 pounds 180.0 g / 1.8 N

When hanging a magnet on a vertical surface (e.g., a car body), it you can count on just about 1/5 of its maximum pull force. Gravity and a low friction coefficient mean that magnets slip easier than they pull off. Designing a vertical fastening? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a significantly smaller load. Utilizing a rubberized layer can drastically improve the result.

2 mm	50%	0.18 kg / 0.40 pounds 180.0 g / 1.8 N
3 mm	75%	0.27 kg / 0.60 pounds 270.0 g / 2.6 N

11 mm	100%	0.36 kg / 0.79 pounds 360.0 g / 3.5 N
12 mm	100%	0.36 kg / 0.79 pounds 360.0 g / 3.5 N

A thin metal plate is not enough to absorb the full magnetic flux, which weakens actual performance of the holder. Should you mount a strong magnet to a weak sheet, the flux will pass right through and the pull force will drop sharply. To squeeze full efficiency of this magnet's potential, you need a suitably thick backing of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the holder works worse. We advise picking the steel dimension according to the table below.

Table 5: Working in heat (stability) - thermal limit
MPL 3x3x2 / N38

Ordinary NdFeB products change their properties strength after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly demagnetize this magnet. With increasing heat, the magnet's capacity temporarily drops. Refrain from using this product close to ovens higher than its operating temperature limit. Ignoring the limit will lead to irreversible degradation of magnetic properties.

*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) may lose charge permanently at lower temperatures compared to rod magnets. Red status in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet setup. The setup of two magnets creates a more powerful interaction and a wider radius of operation. Want to build a strong closure? Apply two magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the collision energy is huge. The repulsion force is slightly lower than the connection force, but still significant.
*Field value in repulsion mode drops to ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Note: Figures show sliding force of a pair of same magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field is a large risk to IT equipment and medical implants. These neodymiums produce a flux that disrupts operation of digital equipment. Remember: the unseen radiation acts through matter and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - warning

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	53.07 km/h (14.74 m/s)	0.01 J

NdFeB products are prone to chipping – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can cause material chips or injury to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when playing with powerful specimens.

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. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical wall, the magnet holds only a fraction of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) severely reduces 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) = 0.66

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.

Model MPL 3x3x2 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 0.36 kg), this product is available immediately from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating block 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 0.36 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.

Plate magnets MPL 3x3x2 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. They work great as invisible mounts under tiles, wood, or glass. 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 3x3x2 / N38, we recommend utilizing strong epoxy glues (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 roughen and wash 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.

This model is characterized by dimensions 3x3x2 mm, which, at a weight of 0.13 g, makes it an element with high energy density. It is a magnetic block with dimensions 3x3x2 mm and a self-weight of 0.13 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of neodymium magnets.

Advantages

Besides their exceptional strength, neodymium magnets offer the following advantages:

They do not lose strength, even over around ten years – the reduction in strength is only ~1% (theoretically),
Magnets effectively defend themselves against loss of magnetization caused by external fields,
By using a smooth layer of nickel, the element acquires an modern look,
Magnets have impressive magnetic induction on the outer side,
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...
Due to the potential of free forming and adaptation to specialized needs, NdFeB magnets can be produced in a broad palette of geometric configurations, which amplifies use scope,
Universal use in modern technologies – they are commonly used in mass storage devices, brushless drives, medical equipment, also other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices

Disadvantages

Disadvantages of neodymium magnets:

They are fragile 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
Neodymium magnets lose their force 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
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing nuts and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
Due to complex production process, their price is higher than average,

Lifting parameters

Magnetic strength at its maximum – what it depends on?

The load parameter shown refers to the maximum value, recorded under laboratory conditions, namely:

on a plate made of structural steel, optimally conducting the magnetic flux
with a thickness minimum 10 mm
with a surface perfectly flat
without the slightest clearance between the magnet and steel
under vertical force vector (90-degree angle)
at standard ambient temperature

Determinants of practical lifting force of a magnet

It is worth knowing that the application force will differ depending on elements below, starting with the most relevant:

Clearance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the flux to be lost into the air.
Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the holding force.

Precautions when working with NdFeB magnets

Respect the power

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

Keep away from computers

Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.

Life threat

People with a heart stimulator must keep an large gap from magnets. The magnetic field can interfere with the functioning of the implant.

Magnet fragility

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.

Warning for allergy sufferers

Some people suffer from a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Prolonged contact may cause an allergic reaction. We suggest use protective gloves.

Swallowing risk

NdFeB magnets are not toys. Eating a few magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.

Pinching danger

Big blocks can smash fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.

Combustion hazard

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

Heat warning

Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.

GPS Danger

A strong magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Do not bring magnets near a device to prevent damaging the sensors.
