Grip strength decreases significantly per each millimeter of spacing. Remember that even the smallest gap (e.g., contamination, varnish, dust) noticeably weakens the grip. Neodymiums work strongest during direct contact; gap weakens the force. See how quickly the load capacity drop, when the magnet does not adhere flatly to the steel surface. When designing the arrangement, eliminate unnecessary gaps.

This section defines the estimated holding capacity necessary to cause the downward movement of the magnet vertically on a vertical steel plate (assuming typical friction coefficient). This parameter is relative to the distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 25x25x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	5.82 kg / 12.82 lbs 5817.0 g / 57.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	3.88 kg / 8.55 lbs 3878.0 g / 38.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.94 kg / 4.27 lbs 1939.0 g / 19.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	9.70 kg / 21.37 lbs 9695.0 g / 95.1 N

When hanging a holder on a upright plane (e.g., a board), it will maintain barely approx. 20%-30% of nominal attraction strength. Gravity and a low friction coefficient mean that holders move down easier than they pop off the substrate. Designing a hanger? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will slide down under a significantly smaller cargo. Utilizing a rubberized pad can effectively increase the grip.

Table 4: Steel thickness (saturation) - sheet metal selection

3 mm	38%	7.27 kg / 16.03 lbs 7271.3 g / 71.3 N
5 mm	63%	12.12 kg / 26.72 lbs 12118.8 g / 118.9 N
10 mm	100%	19.39 kg / 42.75 lbs 19390.0 g / 190.2 N

12 mm	100%	19.39 kg / 42.75 lbs 19390.0 g / 190.2 N

A thin metal plate cannot focus the entire magnetic field, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the field will penetrate right through and the attraction force will be weaker. To utilize 100% of this neodymium's power, you require a sufficiently solid element of steel. The saturation effect causes that on thin elements (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel cross-section based on the following data.

Classic neodymiums irreversibly lose parameters past the thermal threshold. Avoid high temperatures – heat can permanently destroy this magnet. As the temperature rises, the neodymium's capacity temporarily decreases. Refrain from using this magnet in hot environments higher than its safe range. Exceeding the critical threshold will lead to irreversible degradation of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) risk losing magnetic properties sooner than long magnets. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a much further distance than a magnet and steel setup. The setup of two magnets produces a massive flux and a larger range of action. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the impact force is huge. The levitation is marginally weaker than the connection force, but still large.
*Field value for N-N configuration reaches ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Attention: Results demonstrate shear force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a serious hazard to electronics and medical implants. These neodymiums produce a field that destroys function of digital equipment. Be aware: the invisible magnetic field penetrates the body and glass. Exceptional care must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear safety glasses when working with large magnets.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Note: On a vertical wall, the magnet holds merely ~20% of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) significantly limits 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) = 0.46

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.

615.00 ZŁ brutto / pcs

Component MPL 25x25x10 / N38 features a low profile and professional pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 190.25 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. To separate the MPL 25x25x10 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, 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.

They constitute a key element in the production of wind generators and material handling systems. They work great as fasteners under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 25x25x10 / N38, we recommend utilizing 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 clean and degrease 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. In practice, this means that this magnet has the greatest attraction force on its main planes (25x25 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 25x25x10 mm, which, at a weight of 46.88 g, makes it an element with high energy density. It is a magnetic block with dimensions 25x25x10 mm and a self-weight of 46.88 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of rare earth magnets.

Benefits

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

Their strength is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
Neodymium magnets are distinguished by extremely resistant to demagnetization caused by external field sources,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to look better,
They show high magnetic induction at the operating surface, making them more effective,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of custom creating as well as modifying to specific applications,
Wide application in advanced technology sectors – they are used in HDD drives, brushless drives, medical devices, as well as technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in miniature devices

Weaknesses

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
Limited ability of creating nuts in the magnet and complicated shapes - recommended is casing - magnetic holder.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these products are able to complicate diagnosis medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Best holding force of the magnet in ideal parameters – what it depends on?

Breakaway force was determined for ideal contact conditions, taking into account:

using a plate made of low-carbon steel, acting as a magnetic yoke
possessing a massiveness of min. 10 mm to ensure full flux closure
with a surface perfectly flat
with total lack of distance (without impurities)
during detachment in a direction perpendicular to the plane
at ambient temperature room level

Determinants of lifting force in real conditions

Bear in mind that the application force will differ influenced by elements below, in order of importance:

Gap (betwixt the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
Load vector – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
Metal 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 admixtures decrease magnetic permeability and holding force.
Plate texture – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.

Warnings

Do not drill into magnets

Dust created during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Keep away from electronics

A powerful magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Do not bring magnets near a smartphone to avoid breaking the sensors.

Nickel allergy

A percentage of the population suffer from a sensitization to Ni, which is the common plating for NdFeB magnets. Prolonged contact can result in a rash. It is best to wear protective gloves.

Beware of splinters

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Conscious usage

Exercise caution. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can react.

Electronic devices

Device Safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, timepieces).

Choking Hazard

Only for adults. Tiny parts can be swallowed, causing serious injuries. Store away from kids and pets.

Life threat

Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Thermal limits

Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
