Magnetic force weakens sharply with every subsequent millimeter of spacing. Keep in mind that even a microscopic distance (e.g., contamination, varnish, veneer) noticeably weakens the grip. Neodymiums work strongest at the point of direct contact; distance drastically cuts the power. Observe how quickly the parameters fall, when the product does not touch directly to the steel surface. When calculating the mounting, eliminate additional spacers.

This section indicates the estimated shear load required to initiate the slippage of the magnet down against a vertical steel plate (considering typical friction coefficient). The holding force depends on the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MPL 30x20x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	5.86 kg / 12.92 pounds 5859.0 g / 57.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	3.91 kg / 8.61 pounds 3906.0 g / 38.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.95 kg / 4.31 pounds 1953.0 g / 19.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	9.77 kg / 21.53 pounds 9765.0 g / 95.8 N

When mounting a element on a upright wall (e.g., a board), it will maintain barely about 20%-30% of its maximum pull force. Gravitational force and a weak degree of grip cause that products slip faster than they pop off the substrate. Designing a vertical fastening? Consider that the sliding force is significantly lower than the maximum static pull force. On a smooth steel, the element will slide down under a significantly smaller weight. Application of an anti-slip coating can drastically increase the grip.

A thin metal plate is unable to focus the entire magnetic field, which weakens actual performance of the holder. If you install a neodymium to a thin surface, the field will pass right through and the holding will be smaller. To utilize full efficiency of this magnet's potential, you require a sufficiently solid backing of metal. The saturation effect causes that on sheet metal structures (e.g., car bodies), the magnet shows lower pull force. We recommend selecting the steel dimension based on the following data.

Classic neodymiums change their properties strength past the thermal threshold. Watch out for overheating – high temperature can irreversibly demagnetize this magnet. With increasing heat, the neodymium's force momentarily lowers. Avoid using this magnet near heat sources higher than its operating temperature limit. Exceeding the critical threshold will cause permanent loss of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures compared to rod magnets. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and sheet combination. The connection of magnet-to-magnet generates a stronger field and a further horizon of action. Designing a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Exercise caution that when bringing together two magnets, the impact force is extreme. The repulsion force is slightly lower than the attraction, but still significant.
*Flux density in repulsion mode reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Estimates apply to shear force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a serious hazard to electronics and medical implants. These NdFeB products generate a flux that disrupts operation of sensitive medical devices. Notice: the unseen radiation passes through tissues and glass. Increased vigilance must be taken by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - warning

Neodymium magnets are delicate – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or dangerous crushing to skin. 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 magnet. Wear safety glasses when playing with large magnets.

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

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Caution: On a vertical surface, the magnet retains merely a fraction of its nominal pull.

2. Steel thickness impact

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Heat tolerance

*For N38 material, the max working temp 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.

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 30x20x10 mm and a weight of 45 g, guarantees the highest quality connection. This magnetic block with a force of 191.55 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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 19.53 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. Thanks to the flat surface and high force (approx. 19.53 kg), they are ideal as closers in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 30x20x10 / N38, it is best to use 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 roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 30x20x10 / N38 model is magnetized axially (dimension 10 mm), which means that the N and S poles are located on its largest, flat surfaces. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 30 mm (length), 20 mm (width), and 10 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 19.53 kg (force ~191.55 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Benefits

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

They do not lose magnetism, even after nearly 10 years – the drop in strength is only ~1% (theoretically),
They have excellent resistance to magnetic field loss as a result of opposing magnetic fields,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to look better,
They feature high magnetic induction at the operating surface, which improves attraction properties,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
Thanks to the ability of flexible molding and adaptation to specialized needs, neodymium magnets can be modeled in a wide range of shapes and sizes, which increases their versatility,
Fundamental importance in electronics industry – they are used in HDD drives, electric drive systems, diagnostic systems, and other advanced devices.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise 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
Due to limitations in producing nuts and complex forms in magnets, we recommend using a housing - magnetic mount.
Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these products are able to be problematic in diagnostics medical in case of swallowing.
Due to expensive raw materials, their price is higher than average,

Pull force analysis

Maximum lifting capacity of the magnet – what contributes to it?

Breakaway force is the result of a measurement for optimal configuration, including:

on a plate made of mild steel, optimally conducting the magnetic flux
whose transverse dimension is min. 10 mm
with a plane perfectly flat
under conditions of ideal adhesion (metal-to-metal)
for force acting at a right angle (in the magnet axis)
at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

Effective lifting capacity impacted by working environment parameters, mainly (from priority):

Air gap (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
Temperature – temperature increase results in weakening of force. Check 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, whereas under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Precautions when working with neodymium magnets

Choking Hazard

Only for adults. Tiny parts can be swallowed, leading to serious injuries. Keep out of reach of children and animals.

GPS Danger

A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets near a device to prevent damaging the sensors.

Conscious usage

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

Do not overheat magnets

Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

Medical implants

Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Protect data

Intense magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Bodily injuries

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!

Allergy Warning

Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact and select versions in plastic housing.

Protective goggles

NdFeB magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them shattering into shards.

Do not drill into magnets

Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
