1. Wall mount (shear)

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

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) significantly limits the holding force.

3. Power loss vs temp

*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.

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. Additionally, 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. Watch your fingers! Magnets with a force of 35.61 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
Plate magnets MPL 60x20x10 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 35.61 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.
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. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.
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.
The presented product is a neodymium magnet with precisely defined parameters: 60 mm (length), 20 mm (width), and 10 mm (thickness). It is a magnetic block with dimensions 60x20x10 mm and a self-weight of 90 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of neodymium magnets.

Pros

Besides their tremendous strength, neodymium magnets offer the following advantages:
  • They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
  • Magnets effectively resist against demagnetization caused by ambient magnetic noise,
  • In other words, due to the smooth surface of nickel, the element looks attractive,
  • The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
  • Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
  • Possibility of exact shaping and adapting to atypical needs,
  • Huge importance in advanced technology sectors – they are utilized in mass storage devices, drive modules, advanced medical instruments, also technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions

Cons

Disadvantages of NdFeB magnets:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
  • When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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 immune to moisture, in case of application outdoors
  • Limited possibility of producing threads in the magnet and complicated shapes - recommended is a housing - magnet mounting.
  • Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small components of these products can be problematic in diagnostics medical in case of swallowing.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Maximum lifting force for a neodymium magnet – what it depends on?

The force parameter is a measurement result executed under specific, ideal conditions:
  • with the application of a yoke made of special test steel, ensuring maximum field concentration
  • possessing a thickness of at least 10 mm to ensure full flux closure
  • characterized by even structure
  • with total lack of distance (without coatings)
  • during pulling in a direction vertical to the mounting surface
  • at conditions approx. 20°C

Practical aspects of lifting capacity – factors

In practice, the actual lifting capacity results from many variables, ranked from crucial:
  • Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
  • Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
  • Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
  • Surface condition – ground elements ensure maximum contact, which improves force. Uneven metal weaken the grip.
  • Thermal environment – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the holding force.

H&S for magnets
Keep away from electronics

A powerful magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a device to avoid breaking the sensors.

Finger safety

Pinching hazard: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.

Danger to the youngest

Only for adults. Small elements pose a choking risk, causing serious injuries. Store out of reach of children and animals.

Medical interference

For implant holders: Powerful magnets affect medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

Do not underestimate power

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

Shattering risk

Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them cracking into shards.

Skin irritation risks

Studies show that nickel (the usual finish) is a common allergen. If you have an allergy, refrain from direct skin contact or opt for coated magnets.

Magnetic media

Device Safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).

Fire warning

Dust produced during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Heat sensitivity

Keep cool. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).
