1. Shear force

*Warning: On a vertical surface, the magnet retains just ~20% of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely reduces 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) = 0.35

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 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.

Magnetic Field

Other proposals

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 60x20x10 mm and a weight of 90 g, guarantees premium class connection. As a magnetic bar with high power (approx. 35.61 kg), this product is available immediately from our warehouse in Poland. 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. Watch your fingers! Magnets with a force of 35.61 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.
Plate magnets MPL 60x20x10 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.
Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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).
Standardly, the MPL 60x20x10 / N38 model is magnetized through the thickness (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: 60 mm (length), 20 mm (width), and 10 mm (thickness). The key parameter here is the holding force amounting to approximately 35.61 kg (force ~349.34 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Pros and cons of Nd2Fe14B magnets.

Pros

Besides their durability, neodymium magnets are valued for these benefits:
  • They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
  • Magnets very well protect themselves against loss of magnetization caused by ambient magnetic noise,
  • Thanks to the reflective finish, the surface of nickel, gold, or silver-plated gives an clean appearance,
  • Magnets have huge magnetic induction on the outer layer,
  • Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
  • Possibility of accurate creating and modifying to precise applications,
  • Wide application in modern technologies – they are commonly used in magnetic memories, electric motors, diagnostic systems, as well as technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in compact constructions

Cons

Drawbacks and weaknesses of neodymium magnets: application proposals
  • To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Limited possibility of producing nuts in the magnet and complicated forms - preferred is casing - magnet mounting.
  • Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
  • Due to neodymium price, their price is relatively high,

Pull force analysis

Maximum lifting force for a neodymium magnet – what contributes to it?

Holding force of 35.61 kg is a result of laboratory testing performed under specific, ideal conditions:
  • on a base made of mild steel, optimally conducting the magnetic flux
  • with a thickness minimum 10 mm
  • with a surface cleaned and smooth
  • with direct contact (without paint)
  • under vertical force vector (90-degree angle)
  • at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

During everyday use, the actual lifting capacity is determined by a number of factors, listed from crucial:
  • Gap (betwixt the magnet and the metal), since even a very small distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
  • Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
  • Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
  • Steel type – mild steel attracts best. Alloy admixtures lower magnetic permeability and lifting capacity.
  • Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
  • Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, however 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 lifting capacity.

Warnings
Powerful field

Handle magnets with awareness. Their huge power can shock even professionals. Be vigilant and respect their power.

GPS and phone interference

Note: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, device, and navigation systems.

Warning for heart patients

Patients with a heart stimulator should keep an safe separation from magnets. The magnetism can interfere with the functioning of the life-saving device.

Product not for children

Only for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep out of reach of kids and pets.

Nickel coating and allergies

It is widely known that the nickel plating (the usual finish) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands and opt for versions in plastic housing.

Safe distance

Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.

Mechanical processing

Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.

Crushing force

Pinching hazard: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.

Heat sensitivity

Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its properties and pulling force.

Magnet fragility

Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
