Magnetic force decreases drastically with every subsequent millimeter of gap. Note that even a microscopic distance (e.g., dirt, varnish, dust) strongly diminishes the holding power. Neodymiums operate strongest at the point of direct contact; distance drastically cuts the force. Analyze how quickly the load capacity plummet, when the product does not touch directly to the steel surface. When calculating the mounting, discard redundant distances.

The following data presents the approximate shear load necessary to start the downward movement of the magnet vertically against a upright steel wall (assuming standard friction). The holding force is a function of the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	10.12 kg / 22.31 LBS 10119.0 g / 99.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	6.75 kg / 14.87 LBS 6746.0 g / 66.2 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	16.87 kg / 37.18 LBS 16865.0 g / 165.4 N

When placing a magnet on a upright wall (e.g., a fridge), it will maintain just approx. 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient mean that magnets move down faster than they detach. Designing a vertical fastening? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will give way down under a noticeably lighter load. Utilizing a rubberized pad can drastically increase the grip.

A thin sheet is incapable of take in the full magnetic flux, which weakens actual performance of the magnet. If you install a neodymium to a too thin substrate, the flux will pass right through and the attraction force will be weaker. To achieve full efficiency of this neodymium's potential, you require a sufficiently solid piece of steel. The saturation effect means that on sheet metal structures (e.g., car bodies), the magnet works worse. We suggest choosing the steel thickness from these parameters.

Ordinary NdFeB products lose strength above the temperature limit. Protect against heat – excessive heat can permanently damage this magnet. With every degree above norm, the neodymium's force momentarily decreases. Refrain from using this product close to ovens exceeding its working range. Too high temperature will lead to irreversible degradation of magnetic properties.

*Technical advisory: Thermal stability is determined by both grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnetic products 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 action. Designing a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the pinch force is huge. The levitation is marginally weaker than the connection force, but still impressive.
*Field value in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Estimates demonstrate shear force of dual same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to IT equipment as well as medical implants. These NdFeB products generate a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel causes immediate chipping. Control the attraction moment – a neodymium left loose becomes dangerous. Kinetic force can destroy the magnet or dangerous crushing to fingers. 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 magnet. Use safety goggles when working with powerful specimens.

Corrosion 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. Buoyancy helps in lifting finds.

1. Vertical hold

*Caution: On a vertical wall, the magnet retains just approx. 20-30% of its perpendicular strength.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) severely limits the holding force.

3. Temperature resistance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.26

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.

Component MPL 50x50x10 / N38 features a flat shape and professional pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 33.73 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is shifting the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. Watch your fingers! Magnets with a force of 33.73 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 50x50x10 / 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. 33.73 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 50x50x10 / 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 clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 50x50x10 / N38 model is magnetized through the thickness (dimension 10 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 (50x50 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: 50 mm (length), 50 mm (width), and 10 mm (thickness). It is a magnetic block with dimensions 50x50x10 mm and a self-weight of 187.5 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of rare earth magnets.

Benefits

Besides their immense field intensity, neodymium magnets offer the following advantages:

They do not lose magnetism, even after approximately ten years – the decrease in strength is only ~1% (theoretically),
Magnets effectively defend themselves against demagnetization caused by external fields,
In other words, due to the smooth surface of gold, the element gains a professional look,
Magnetic induction on the working layer of the magnet turns out to be extremely intense,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
Thanks to the option of accurate forming and customization to custom needs, magnetic components can be created in a broad palette of geometric configurations, which amplifies use scope,
Versatile presence in modern industrial fields – they are utilized in data components, electric drive systems, medical devices, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in miniature devices

Limitations

Drawbacks and weaknesses of neodymium magnets and ways of using them

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
Neodymium magnets lose their power 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
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Limited possibility of creating threads in the magnet and complicated forms - preferred is casing - mounting mechanism.
Possible danger related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Maximum magnetic pulling force – what it depends on?

Magnet power was defined for ideal contact conditions, including:

using a sheet made of high-permeability steel, acting as a circuit closing element
whose transverse dimension is min. 10 mm
with an polished touching surface
with total lack of distance (without impurities)
under vertical application of breakaway force (90-degree angle)
in temp. approx. 20°C

Magnet lifting force in use – key factors

Please note that the magnet holding will differ influenced by elements below, in order of importance:

Clearance – existence of foreign body (paint, dirt, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Base massiveness – too thin sheet does not close the flux, causing part of the flux to be lost to the other side.
Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet and the plate decreases the holding force.

Safety rules for work with NdFeB magnets

Magnetic media

Device Safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, timepieces).

Danger to pacemakers

Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Nickel allergy

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease working with magnets and wear gloves.

Powerful field

Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.

Shattering risk

Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.

Magnetic interference

Be aware: rare earth magnets produce a field that confuses sensitive sensors. Maintain a separation from your phone, tablet, and navigation systems.

Dust explosion hazard

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

Heat sensitivity

Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.

No play value

Product intended for adults. Small elements pose a choking risk, causing severe trauma. Keep out of reach of kids and pets.

Bodily injuries

Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
