1. Wall mount (shear)

*Note: On a vertical wall, the magnet retains merely ~20% of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Temperature resistance

*For N38 grade, the max working temp 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.

Model MPL 6x6x6 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 13.54 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. Watch your fingers! Magnets with a force of 1.38 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 6x6x6 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 1.38 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.
For mounting flat magnets MPL 6x6x6 / 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 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. In practice, this means that this magnet has the greatest attraction force on its main planes (6x6 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: 6 mm (length), 6 mm (width), and 6 mm (thickness). It is a magnetic block with dimensions 6x6x6 mm and a self-weight of 1.62 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of neodymium magnets.

Strengths

Besides their immense strength, neodymium magnets offer the following advantages:
  • They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
  • They have excellent resistance to magnetism drop when exposed to external fields,
  • A magnet with a metallic gold surface looks better,
  • The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Thanks to modularity in shaping and the capacity to modify to unusual requirements,
  • Huge importance in advanced technology sectors – they are used in magnetic memories, brushless drives, precision medical tools, as well as complex engineering applications.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals
  • At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
  • Due to limitations in creating threads and complicated forms in magnets, we propose using cover - magnetic mount.
  • Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
  • With large orders the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum lifting force for a neodymium magnet – what affects it?

The load parameter shown concerns the maximum value, measured under optimal environment, namely:
  • with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
  • whose transverse dimension equals approx. 10 mm
  • with an ground contact surface
  • without the slightest insulating layer between the magnet and steel
  • for force acting at a right angle (in the magnet axis)
  • at room temperature

Lifting capacity in real conditions – factors

In practice, the actual lifting capacity is determined by several key aspects, ranked from crucial:
  • Clearance – the presence of any layer (rust, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Base massiveness – insufficiently thick plate does not accept the full field, causing part of the flux to be wasted into the air.
  • Plate material – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and lifting capacity.
  • Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
  • Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the lifting capacity.

Safety rules for work with neodymium magnets
Safe distance

Very strong magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Medical implants

People with a pacemaker should keep an large gap from magnets. The magnetism can disrupt the operation of the life-saving device.

Precision electronics

A powerful magnetic field negatively affects the operation of compasses in phones and navigation systems. Keep magnets close to a device to avoid damaging the sensors.

Fire risk

Powder produced during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Adults only

These products are not suitable for play. Eating multiple magnets may result in them attracting across intestines, which poses a direct threat to life and requires immediate surgery.

Do not overheat magnets

Monitor thermal conditions. Heating the magnet to high heat will ruin its magnetic structure and pulling force.

Fragile material

Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.

Bone fractures

Risk of injury: The pulling power is so immense that it can result in blood blisters, crushing, and broken bones. Use thick gloves.

Sensitization to coating

Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, refrain from direct skin contact or choose coated magnets.

Respect the power

Be careful. Rare earth magnets act from a distance and snap with huge force, often quicker than you can move away.
