Grip strength weakens significantly per each millimeter of distance. Remember that even a very thin break (e.g., dirt, paint, veneer) noticeably weakens the grip. Magnetic products hold most effectively during direct contact; air break weakens the force. Analyze how flashily the parameters drop, when the product does not touch flatly to the steel surface. When planning the assembly, avoid redundant distances.

The table below indicates the estimated weight limit sufficient to start the sliding of the magnet down against a upright metal surface (considering standard friction coefficient). This parameter varies with the gap size between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MPL 3x3x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.10 kg / 0.22 lbs 102.0 g / 1.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.07 kg / 0.15 lbs 68.0 g / 0.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.03 kg / 0.07 lbs 34.0 g / 0.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.17 kg / 0.37 lbs 170.0 g / 1.7 N

When mounting a element on a vertical wall (e.g., a car body), it you can count on only about 20%-30% of nominal attraction strength. Gravitational force as well as a low friction coefficient influence the fact that products slip faster than they pull off. Want to create a hanger? Note that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a much lighter cargo. Utilizing a rubberized layer can significantly increase the grip.

12 mm	100%	0.34 kg / 0.75 lbs 340.0 g / 3.3 N

A thin sheet is incapable of absorb the full magnetic flux, which wastes potential of the magnet. If you install a neodymium to a thin surface, the flux will penetrate right through and the holding will be smaller. To squeeze 100% of this magnet's power, you need a suitably thick backing of metal. The saturation effect means that on thin elements (e.g., appliance housings), the holder works worse. We suggest choosing the steel dimension based on the following data.

Standard neodymium magnets change their properties power past the thermal threshold. Watch out for overheating – excessive heat can permanently demagnetize this magnet. With increasing heat, the neodymium's power temporarily lowers. Refrain from using this product in hot environments higher than its operating temperature limit. Exceeding the critical threshold will lead to irreversible degradation of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) may lose charge permanently sooner than taller cylinders. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnets interact from a much further distance than a neodymium and metal setup. The setup of two magnets generates a stronger field and a larger range of action. Designing a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is a bit weaker than the attraction, but still impressive.
*The magnetic induction between like poles is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Attention: Calculations apply to shear force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to electronics as well as pacemakers. These neodymiums produce a flux that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation acts through matter and plastic. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

NdFeB products are very brittle – a violent impact against metal risks their cracking. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when handling with large magnets.

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

1. Shear force

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

2. Efficiency vs thickness

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

3. Temperature resistance

*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) = 0.84

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 plate magnet made of NdFeB material, which, with dimensions of 3x3x3 mm and a weight of 0.2 g, guarantees the highest quality connection. This rectangular block with a force of 3.37 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.

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 0.34 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. 0.34 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 3x3x3 / 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 roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 3x3x3 / N38 model is magnetized axially (dimension 3 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (3x3 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 3x3x3 mm, which, at a weight of 0.2 g, makes it an element with impressive energy density. The key parameter here is the lifting capacity amounting to approximately 0.34 kg (force ~3.37 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Benefits

Besides their remarkable pulling force, neodymium magnets offer the following advantages:

They do not lose power, even during nearly 10 years – the reduction in strength is only ~1% (based on measurements),
They maintain their magnetic properties even under strong external field,
By covering with a shiny coating of nickel, the element acquires an proper look,
They show high magnetic induction at the operating surface, which affects their effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
Considering the option of flexible forming and customization to unique requirements, neodymium magnets can be manufactured in a broad palette of shapes and sizes, which makes them more universal,
Universal use in future technologies – they serve a role in HDD drives, motor assemblies, medical devices, as well as multitasking production systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets decrease their force 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 durability even at temperatures up to 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 and corrosion.
We suggest casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these magnets can disrupt the diagnostic process medical after entering the body.
Due to complex production process, their price exceeds standard values,

Lifting parameters

Detachment force of the magnet in optimal conditions – what it depends on?

The force parameter is a result of laboratory testing executed under standard conditions:

on a plate made of mild steel, perfectly concentrating the magnetic field
with a thickness no less than 10 mm
with an ideally smooth touching surface
under conditions of gap-free contact (metal-to-metal)
under vertical force direction (90-degree angle)
in neutral thermal conditions

What influences lifting capacity in practice

During everyday use, the real power is determined by several key aspects, ranked from most significant:

Distance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
Surface condition – ground elements ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet’s surface and the plate reduces the load capacity.

Precautions when working with neodymium magnets

Electronic devices

Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.

Warning for heart patients

Patients with a pacemaker must maintain an absolute distance from magnets. The magnetism can disrupt the functioning of the life-saving device.

Fire warning

Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Do not underestimate power

Handle magnets consciously. Their immense force can shock even experienced users. Be vigilant and respect their power.

Heat warning

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

GPS Danger

An intense magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Keep magnets close to a smartphone to prevent breaking the sensors.

Metal Allergy

Certain individuals experience a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Frequent touching can result in skin redness. It is best to use safety gloves.

Magnet fragility

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Swallowing risk

Strictly keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are very dangerous.

Finger safety

Big blocks can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
