Pulling power decreases significantly with every subsequent millimeter of distance. Keep in mind that even a microscopic distance (e.g., dirt, paint, dust) noticeably reduces the pull force. Magnets operate most effectively at the point of direct contact; distance weakens the force. Notice how quickly the pull force plummet, when the magnet does not adhere directly to the steel surface. When calculating the assembly, eliminate additional spacers.

The table below calculates the theoretical weight limit needed to initiate the sliding of the magnet down against a vertical steel wall (considering standard friction coefficient). This value varies with the air gap between the magnet and the surface.

When hanging a magnet on a vertical surface (e.g., a board), it will only hold only approx. 1/5 of its maximum pull force. Gravity and a weak degree of grip cause that holders move down easier than they detach. Planning a hanger? Note that the shear force is much weaker than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a noticeably lighter load. Using a rubber coating can drastically increase the grip.

A too thin steel cannot focus the full magnetic flux, which weakens actual performance of the magnet. Should you mount a strong magnet to a thin surface, the field will penetrate right through and the holding will be smaller. To squeeze 100% of this magnet's power, you require a sufficiently solid backing of metal. The material oversaturation causes that on thin elements (e.g., appliance housings), the magnet works worse. We advise picking the steel dimension from these parameters.

Ordinary NdFeB products irreversibly lose parameters after exceeding the maximum temperature. Avoid high temperatures – heat can irreversibly damage this magnet. With every degree above norm, the magnet's force momentarily decreases. Do not use this product near heat sources higher than its working range. Exceeding the critical threshold will lead to destruction of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums attract each other from a wider radius than a magnet and steel setup. The connection of magnet-to-magnet produces a massive flux and a further horizon of performance. Planning to create a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Be careful that when bringing together two magnets, the collision energy is extreme. The levitation is slightly lower than the attraction, but still significant.
*Field value for N-N configuration reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Important: Calculations apply to sliding force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field is a real danger to electronic devices as well as medical implants. These NdFeB products produce a field that disrupts operation of digital equipment. Be aware: the invisible magnetic field acts through matter and plastic. Exceptional care must be taken by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are prone to chipping – a strong collision with metal causes immediate chipping. Control the attraction moment – a neodymium left loose becomes dangerous. Impact energy can destroy the magnet or dangerous crushing to fingers. Be sure to control the product during installation so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the neodymium. Use safety goggles when handling with powerful specimens.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Warning: On a vertical surface, the magnet retains merely approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) drastically reduces 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) = 0.84

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.

0.996 ZŁ brutto / pcs

Component MPL 20x20x20 / N38 features a low profile and professional pulling force, making it an ideal solution for building separators and machines. This rectangular block with a force of 151.12 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.

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. To separate the MPL 20x20x20 / 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 generators and material handling systems. They work great as fasteners under tiles, wood, or glass. 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 20x20x20 / 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.

Standardly, the MPL 20x20x20 / N38 model is magnetized axially (dimension 20 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 (20x20 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: 20 mm (length), 20 mm (width), and 20 mm (thickness). It is a magnetic block with dimensions 20x20x20 mm and a self-weight of 60 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of rare earth magnets.

Strengths

Besides their remarkable magnetic power, neodymium magnets offer the following advantages:

They retain magnetic properties for around ten years – the drop is just ~1% (based on simulations),
They maintain their magnetic properties even under external field action,
The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
Magnetic induction on the working layer of the magnet remains maximum,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Thanks to versatility in constructing and the capacity to modify to specific needs,
Key role in high-tech industry – they are used in data components, brushless drives, advanced medical instruments, also complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in small systems

Limitations

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets decrease 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 resistant to moisture, in case of application outdoors
Limited ability of making threads in the magnet and complicated shapes - preferred is a housing - magnet mounting.
Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small elements of these magnets can be problematic in diagnostics medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Magnetic strength at its maximum – what contributes to it?

The lifting capacity listed is a measurement result conducted under specific, ideal conditions:

with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
with a cross-section no less than 10 mm
with a plane cleaned and smooth
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
in stable room temperature

Determinants of lifting force in real conditions

Please note that the magnet holding will differ depending on the following factors, in order of importance:

Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material composition – different alloys reacts the same. High carbon content worsen the attraction effect.
Surface finish – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Precautions when working with NdFeB magnets

Crushing risk

Large magnets can smash fingers instantly. Never put your hand betwixt two strong magnets.

Implant safety

For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.

Shattering risk

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Precision electronics

An intense magnetic field interferes with the functioning of compasses in phones and navigation systems. Keep magnets near a smartphone to prevent breaking the sensors.

Do not give to children

Absolutely keep magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are very dangerous.

Flammability

Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Keep away from computers

Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Nickel coating and allergies

Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness appears, cease working with magnets and wear gloves.

Heat sensitivity

Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.

Powerful field

Handle magnets with awareness. Their powerful strength can surprise even experienced users. Stay alert and respect their power.
