Pulling power decreases significantly with every mm of spacing. Remember that even a microscopic distance (e.g., dirt, varnish, veneer) significantly weakens the grip. Neodymiums hold strongest during direct contact; gap nullifies the force. Notice how quickly the parameters plummet, when the magnet does not adhere tightly to the metal substrate. When planning the arrangement, eliminate additional spacers.

The table below shows the theoretical weight limit sufficient to start the downward movement of the magnet down on a upright metal surface (assuming typical friction coefficient). This value varies with the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MPL 3x3x2 / N38

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

When mounting a holder on a vertical surface (e.g., a board), it will maintain just about 1/5 of its maximum pull force. Gravity and a weak degree of grip mean that products move down easier than they pull off. Designing a hanger? Remember that the sliding force is noticeably lower than the maximum static pull force. On a slippery surface, the element will give way down under a significantly smaller load. Application of an anti-slip layer can effectively increase the grip.

A too thin steel is not enough to take in the full magnetic flux, which weakens actual performance of the magnet. If you mount a strong magnet to a weak sheet, the flux will penetrate right through and the holding will be smaller. To utilize 100% of this magnet's potential, you need a suitably thick backing of steel. The saturation effect causes that on sheet metal structures (e.g., thin profiles), the magnet holds weaker. We advise picking the steel thickness based on the following data.

Standard neodymium magnets change their properties power above the temperature limit. Watch out for overheating – high temperature can permanently destroy this product. As the temperature rises, the neodymium's power temporarily drops. Refrain from using this magnet in hot environments exceeding its operating temperature limit. Too high temperature will lead to permanent loss of magnetic properties.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (pancake types) risk losing magnetic properties at lower temperatures than taller cylinders. Red status in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and steel setup. The setup of two magnets generates a stronger field and a further horizon of performance. Planning to create a strong closure? Apply two magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the impact force is massive. The levitation is a bit weaker than the connection force, but still large.
*Flux density for N-N configuration drops to ~0 Gs at the midpoint between the magnets (due to field cancellation).
Attention: Figures refer to sliding force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field is a serious hazard to electronics and medical implants. These NdFeB products generate a field that disrupts operation of sensitive medical devices. Be aware: the unseen radiation penetrates the body and plastic. Increased vigilance 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 place the magnet near cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a collision with steel causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can trigger coating fragments or injury to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when handling with powerful specimens.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) severely reduces the holding force.

3. Thermal stability

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.66

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 plate magnet made of NdFeB material, which, with dimensions of 3x3x2 mm and a weight of 0.13 g, guarantees the highest quality connection. 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. To separate the MPL 3x3x2 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, 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.

Plate magnets MPL 3x3x2 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 0.36 kg), they are ideal as hidden locks 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.

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. 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 3x3x2 / N38 model is magnetized axially (dimension 2 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.

The presented product is a neodymium magnet with precisely defined parameters: 3 mm (length), 3 mm (width), and 2 mm (thickness). The key parameter here is the holding force amounting to approximately 0.36 kg (force ~3.49 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of neodymium magnets.

Strengths

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

They do not lose magnetism, even during nearly 10 years – the reduction in power is only ~1% (based on measurements),
Neodymium magnets are extremely resistant to demagnetization caused by external interference,
A magnet with a shiny gold surface has better aesthetics,
The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of individual machining as well as adapting to complex applications,
Huge importance in modern industrial fields – they are used in data components, brushless drives, advanced medical instruments, also multitasking production systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

At very strong impacts they can break, 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 lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited ability of creating nuts in the magnet and complicated shapes - recommended is casing - magnetic holder.
Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
With large orders the cost of neodymium magnets is a challenge,

Pull force analysis

Maximum lifting force for a neodymium magnet – what it depends on?

The load parameter shown represents the limit force, recorded under optimal environment, specifically:

on a block made of structural steel, perfectly concentrating the magnetic flux
whose thickness reaches at least 10 mm
characterized by lack of roughness
without any insulating layer between the magnet and steel
under vertical force direction (90-degree angle)
in neutral thermal conditions

Determinants of practical lifting force of a magnet

Bear in mind that the magnet holding will differ depending on the following factors, starting with the most relevant:

Clearance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
Base massiveness – insufficiently thick sheet does not close the flux, causing part of the power to be escaped into the air.
Steel grade – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.

Warnings

GPS Danger

Remember: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, device, and GPS.

Skin irritation risks

Certain individuals have a contact allergy to Ni, which is the standard coating for NdFeB magnets. Frequent touching can result in skin redness. It is best to wear safety gloves.

Demagnetization risk

Control the heat. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.

Danger to the youngest

NdFeB magnets are not suitable for play. Swallowing multiple magnets may result in them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.

Protective goggles

Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets will cause them breaking into small pieces.

Combustion hazard

Dust produced during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.

Immense force

Handle magnets consciously. Their powerful strength can shock even experienced users. Plan your moves and respect their power.

Danger to pacemakers

Warning for patients: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

Serious injuries

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

Electronic devices

Data protection: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
