Frequently asked questions

How much will a block magnet really hold?
The catalogue force is measured in full contact with smooth steel at least 10 mm thick, pulled perpendicular, at about 20 °C. On 1 mm sheet about 50% of that value remains, on 0.5 mm about 25%. Mounted on a vertical wall the realistic figure is 20–30%, because the load is then in shear rather than in tension.
What is the maximum working temperature?
Standard N-series grades up to 80 °C, and N50, N52 and N54 up to 60 °C. Above the maximum working temperature the loss stops being reversible. The Curie temperature, at which magnetic properties are lost completely, is about 310 °C.
What safety factor should I allow?
At least twice the mass of the item, and three to five times for vertical mounting. The margin covers sheet thickness, surface condition, any layer of paint or rust, and vibration.

Magnetic force drops sharply per each millimeter of spacing. Keep in mind that even the smallest gap (e.g., dirt, paint, dust) significantly diminishes the holding power. Neodymiums hold most effectively at the point of direct contact; air break nullifies the power. Observe how flashily the pull force plummet, when the magnet does not adhere directly to the metal substrate. When calculating the assembly, avoid redundant distances.

The table below presents the theoretical force sufficient to start the shifting of the magnet downwards along a upright metal surface (considering standard friction). The holding force is a function of the air gap between the magnet and the metal.

When mounting a magnet on a upright surface (e.g., a car body), it you can count on just approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip cause that magnets slip easier than they pop off the substrate. Designing a wall mount? Note that the shear force is significantly lower than the maximum static pull force. On a painted metal, the holder will slide down under a noticeably lighter load. Application of an anti-slip coating can effectively raise the stability.

A thin metal plate cannot take in the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a too thin substrate, the field will pass right through and the pull force will drop sharply. To achieve the maximum of this magnet's power, you require a sufficiently solid backing of steel. The material oversaturation means that on sheet metal structures (e.g., car bodies), the product holds weaker. We recommend selecting the steel cross-section based on the following data.

Standard neodymium magnets lose strength above the temperature limit. Protect against heat – high temperature can irreversibly destroy this magnet. As the temperature rises, the magnet's capacity momentarily decreases. Avoid using this magnet 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, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) may lose charge permanently at lower temperatures than taller cylinders. Red status in the table indicates a risk of irreversible loss for this particular item.

Two magnets interact from a significantly greater distance than a magnet and steel combination. Such a system of magnet-to-magnet produces a massive flux and a larger range of action. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the pinch force is huge. The levitation is slightly lower than the connection force, but still impressive.
*Flux density for N-N configuration reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Important: Estimates refer to sliding force of two same magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to electronics and medical implants. These neodymiums produce a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field penetrates the body and glass. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can cause material chips or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when playing with large magnets.

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

*Note: On a vertical surface, the magnet holds only a fraction of its max power.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient Pc (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 Pc (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 Pc 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 20x20x20 mm and a weight of 60 g, guarantees premium class connection. This rectangular block with a force of 151.12 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.
The key to success is sliding 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 care, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 15.40 kg), they are ideal as hidden locks 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 20x20x20 / N38, it is best to use 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).
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.
This model is characterized by dimensions 20x20x20 mm, which, at a weight of 60 g, makes it an element with impressive energy density. The key parameter here is the lifting capacity amounting to approximately 15.40 kg (force ~151.12 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of rare earth magnets.

Strengths

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
  • They have excellent resistance to magnetism drop due to external magnetic sources,
  • A magnet with a shiny gold surface looks better,
  • They show high magnetic induction at the operating surface, which affects their effectiveness,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
  • Thanks to versatility in shaping and the ability to customize to client solutions,
  • Universal use in innovative solutions – they are utilized in mass storage devices, electric drive systems, advanced medical instruments, and technologically advanced constructions.
  • Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Limitations

What to avoid - cons of neodymium magnets and proposals for their use:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Limited ability of creating nuts in the magnet and complicated forms - recommended is cover - magnetic holder.
  • Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
  • With budget limitations the cost of neodymium magnets can be a barrier,

Holding force characteristics

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

The specified lifting capacity refers to the peak performance, measured under laboratory conditions, namely:
  • on a plate made of structural steel, effectively closing the magnetic field
  • with a thickness no less than 10 mm
  • with an ground touching surface
  • with zero gap (without coatings)
  • under perpendicular force direction (90-degree angle)
  • at room temperature

Determinants of practical lifting force of a magnet

In real-world applications, the actual holding force depends on a number of factors, presented from crucial:
  • Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of nominal force).
  • Base massiveness – insufficiently thick steel causes magnetic saturation, causing part of the power to be lost into the air.
  • Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
  • Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
  • Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Precautions when working with NdFeB magnets
Heat warning

Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.

Bone fractures

Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.

Magnet fragility

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets leads to them breaking into small pieces.

Keep away from children

Always keep magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are fatal.

Magnetic interference

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

ICD Warning

For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.

Keep away from computers

Avoid bringing magnets near a wallet, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.

Allergic reactions

It is widely known that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands or choose encased magnets.

Fire risk

Machining of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Immense force

Handle magnets consciously. Their immense force can surprise even experienced users. Be vigilant and do not underestimate their power.
