Magnetic force drops significantly with every mm of distance. Keep in mind that every additional insulation layer (e.g., contamination, paint, dust) significantly diminishes the holding power. Neodymiums hold optimally at the point of direct contact; gap drastically cuts the power. See how quickly the parameters drop, when the magnet does not touch tightly to the steel surface. When calculating the arrangement, avoid additional spacers.

The following data presents the approximate shear load necessary to cause the downward movement of the magnet down on a upright steel plate (assuming typical friction coefficient). This parameter is a function of the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull

Raw steel	µ = 0.3 30% Nominalnej Siły	0.10 kg / 0.21 pounds 96.0 g / 0.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.06 kg / 0.14 pounds 64.0 g / 0.6 N

When mounting a holder on a vertical wall (e.g., a fridge), it will only hold only approx. 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip cause that holders slip easier than they pop off the substrate. Planning a vertical fastening? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a much lighter weight. Using a rubber pad can effectively improve the result.

12 mm	100%	0.32 kg / 0.71 pounds 320.0 g / 3.1 N

A thin metal plate is incapable of take in the entire magnetic field, which weakens actual performance of the holder. Should you install a neodymium to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To utilize the maximum of this neodymium's power, you need a suitably thick backing of steel. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the holder holds weaker. We advise picking the steel cross-section according to the table below.

Classic neodymiums lose strength past the thermal threshold. Avoid high temperatures – high temperature can permanently demagnetize this magnet. With every degree above norm, the neodymium's capacity momentarily drops. Do not use this magnet close to ovens exceeding its working range. Ignoring the limit will result in irreversible degradation of magnetism.

*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) are more susceptible to demagnetization sooner compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a wider radius than a magnet and steel setup. The setup of two magnets generates a stronger field and a wider radius of action. Want to build a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the pinch force is huge. The levitation is a bit weaker than the connection force, but still large.
*Field value in repulsion mode drops to ~0 Gs in the exact middle of the gap (due to field cancellation).
* Figures refer to friction force of a pair of same magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a real danger to electronic devices as well as medical implants. These magnets generate a flux that destroys function of digital equipment. Be aware: the invisible magnetic field penetrates the body and glass. Increased vigilance must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a strong collision with metal risks their cracking. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Kinetic force can destroy the magnet or injury to fingers. Be sure to control the product during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when working 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!

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Note: On a vertical surface, the magnet retains only ~20% of its max power.

2. Steel saturation

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.29

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.

Component MPL 5x4x1 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 0.32 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 0.32 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 5x4x1 / 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. 0.32 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 5x4x1 / 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 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. 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: 5 mm (length), 4 mm (width), and 1 mm (thickness). The key parameter here is the holding force amounting to approximately 0.32 kg (force ~3.16 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of neodymium magnets.

Strengths

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They retain magnetic properties for almost 10 years – the loss is just ~1% (according to analyses),
They maintain their magnetic properties even under external field action,
A magnet with a smooth silver surface has an effective appearance,
Magnetic induction on the working layer of the magnet remains exceptional,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
Thanks to the possibility of precise molding and customization to custom projects, NdFeB magnets can be created in a wide range of shapes and sizes, which amplifies use scope,
Wide application in modern technologies – they find application in data components, electric drive systems, precision medical tools, also technologically advanced constructions.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Limitations

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in realizing threads and complicated shapes in magnets, we recommend using a housing - magnetic holder.
Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to complicate diagnosis medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what contributes to it?

The load parameter shown concerns the maximum value, obtained under laboratory conditions, specifically:

on a base made of mild steel, optimally conducting the magnetic field
possessing a thickness of minimum 10 mm to avoid saturation
with a plane cleaned and smooth
without any clearance between the magnet and steel
during pulling in a direction vertical to the plane
in stable room temperature

Practical aspects of lifting capacity – factors

Real force is influenced by working environment parameters, including (from priority):

Gap (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Plate material – mild steel attracts best. Alloy steels decrease magnetic properties and lifting capacity.
Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Warnings

No play value

Absolutely keep magnets away from children. Risk of swallowing is high, and the effects of magnets connecting inside the body are life-threatening.

Threat to navigation

GPS units and smartphones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.

Mechanical processing

Dust produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Fragile material

Neodymium magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets will cause them shattering into shards.

Pacemakers

Individuals with a heart stimulator should keep an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Handling rules

Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and respect their power.

Safe distance

Do not bring magnets near a wallet, computer, or TV. The magnetism can permanently damage these devices and wipe information from cards.

Allergy Warning

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, cease handling magnets and use protective gear.

Demagnetization risk

Watch the temperature. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.

Serious injuries

Big blocks can smash fingers in a fraction of a second. Do not put your hand between two attracting surfaces.
