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.

Grip strength drops drastically per each millimeter of spacing. Note that even the smallest gap (e.g., dirt, paint, veneer) noticeably reduces the pull force. Magnets hold strongest in perfect adhesion; distance nullifies the power. Analyze how rapidly the parameters drop, when the product does not touch tightly to the metal substrate. When planning the mounting, avoid additional spacers.

When mounting a magnet on a vertical plane (e.g., a board), it you can count on only about 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip mean that holders slip faster than they pull off. Planning a hanger? Remember that the shear force is significantly lower than the maximum static pull force. On a painted metal, the element will slip down under a significantly smaller cargo. Using a rubber pad can significantly raise the stability.

A too thin steel is incapable of take in the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a too thin substrate, the flux will penetrate right through and the attraction force will be weaker. To utilize full efficiency of this magnet's power, you require a sufficiently solid element of metal. The material oversaturation causes that on thin elements (e.g., appliance housings), the holder holds weaker. We recommend selecting the steel cross-section based on the following data.

Ordinary NdFeB products irreversibly lose power past the thermal threshold. Protect against heat – excessive heat can irreversibly destroy this product. As the temperature rises, the magnet's power briefly lowers. Refrain from using this product close to ovens exceeding its operating temperature limit. Too high temperature will result in destruction of magnetic properties.
*Technical advisory: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel setup. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Want to build a powerful holder? Use a pair of magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the impact force is extreme. The levitation is a bit weaker than the attraction, but still significant.
*Flux density for N-N configuration is approximately ~0 Gs at the midpoint between the magnets (due to field cancellation).
* Results apply to friction force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

NdFeB products are delicate – a strong collision with metal causes immediate chipping. Control the attraction moment – a neodymium left loose turns into a projectile. Striking energy can trigger coating fragments or injury to fingers. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed means shattering of the neodymium. Wear eye protection when playing with large magnets.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet retains only a fraction of its perpendicular strength.

2. Plate thickness effect

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

3. Thermal stability

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.38

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 a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 100x40x20 mm and a weight of 600 g, guarantees the highest quality connection. As a block magnet with high power (approx. 120.01 kg), this product is available off-the-shelf from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures 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. To separate the MPL 100x40x20 / 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. 120.01 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 100x40x20 / N38, we recommend utilizing two-component adhesives (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. 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 100x40x20 / 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 (100x40 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.
This model is characterized by dimensions 100x40x20 mm, which, at a weight of 600 g, makes it an element with high energy density. It is a magnetic block with dimensions 100x40x20 mm and a self-weight of 600 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of Nd2Fe14B magnets.

Pros

Besides their tremendous field intensity, neodymium magnets offer the following advantages:
  • They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
  • Neodymium magnets are exceptionally resistant to loss of magnetic properties caused by external interference,
  • By using a smooth coating of gold, the element gains an professional look,
  • Magnets are characterized by exceptionally strong magnetic induction on the outer side,
  • 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...
  • Possibility of accurate machining as well as optimizing to specific applications,
  • Universal use in innovative solutions – they find application in data components, motor assemblies, medical devices, also complex engineering applications.
  • Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Limitations

Disadvantages of NdFeB magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
  • We warn that neodymium magnets can lose their power 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 suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • We suggest casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
  • Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what it depends on?

The load parameter shown concerns the limit force, obtained under ideal test conditions, namely:
  • on a base made of mild steel, perfectly concentrating the magnetic field
  • possessing a thickness of min. 10 mm to ensure full flux closure
  • characterized by smoothness
  • under conditions of ideal adhesion (metal-to-metal)
  • under vertical force vector (90-degree angle)
  • at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

Real force is affected by working environment parameters, mainly (from priority):
  • Clearance – existence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
  • Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost to the other side.
  • Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
  • Surface condition – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
  • Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with NdFeB magnets
Keep away from children

Neodymium magnets are not intended for children. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires immediate surgery.

GPS and phone interference

Remember: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.

Fragile material

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

Do not drill into magnets

Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.

Crushing force

Risk of injury: The pulling power is so immense that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.

Thermal limits

Avoid heat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Data carriers

Equipment safety: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, timepieces).

Warning for allergy sufferers

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease handling magnets and use protective gear.

Life threat

Warning for patients: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.

Immense force

Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
