1. Vertical hold

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

2. Steel thickness impact

*Thin steel (e.g. computer case) severely weakens the holding force.

3. Temperature resistance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.26

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 plate magnet made of NdFeB material, which, with dimensions of 60x10x5 mm and a weight of 22.5 g, guarantees the highest quality connection. As a block magnet with high power (approx. 18.16 kg), this product is available immediately from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.
Separating block 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 18.16 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
They constitute a key element in the production of wind generators and material handling systems. 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.
For mounting flat magnets MPL 60x10x5 / N38, we recommend utilizing two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. 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 60x10x5 / N38 model is magnetized axially (dimension 5 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. This is the most popular configuration for block magnets used in separators and holders.
This model is characterized by dimensions 60x10x5 mm, which, at a weight of 22.5 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 60x10x5 mm and a self-weight of 22.5 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros as well as cons of neodymium magnets.

Advantages

Besides their immense magnetic power, neodymium magnets offer the following advantages:
  • They retain magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
  • Neodymium magnets are distinguished by exceptionally resistant to demagnetization caused by external interference,
  • Thanks to the smooth finish, the surface of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
  • Neodymium magnets create maximum magnetic induction on a small surface, which ensures high operational effectiveness,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Possibility of exact creating as well as optimizing to individual needs,
  • Universal use in modern industrial fields – they are utilized in hard drives, electric motors, precision medical tools, also complex engineering applications.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Cons of neodymium magnets and ways of using them
  • At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
  • Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
  • Limited ability of making threads in the magnet and complex shapes - preferred is a housing - mounting mechanism.
  • Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum holding power of the magnet – what contributes to it?

The specified lifting capacity refers to the maximum value, recorded under laboratory conditions, specifically:
  • on a base made of mild steel, optimally conducting the magnetic flux
  • possessing a thickness of at least 10 mm to avoid saturation
  • characterized by even structure
  • with direct contact (no impurities)
  • for force acting at a right angle (in the magnet axis)
  • in temp. approx. 20°C

Determinants of lifting force in real conditions

In practice, the actual holding force depends on many variables, listed from the most important:
  • Clearance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
  • Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
  • Material type – the best choice is pure iron steel. Hardened steels may attract less.
  • Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
  • Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was assessed by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Safe handling of NdFeB magnets
Fragile material

Neodymium magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets leads to them breaking into shards.

GPS and phone interference

A strong magnetic field disrupts the operation of compasses in phones and GPS navigation. Maintain magnets close to a device to prevent damaging the sensors.

Warning for allergy sufferers

A percentage of the population experience a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in dermatitis. We suggest use protective gloves.

Choking Hazard

These products are not suitable for play. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates immediate surgery.

Finger safety

Large magnets can crush fingers in a fraction of a second. Do not place your hand between two attracting surfaces.

Thermal limits

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.

Keep away from computers

Do not bring magnets close to a wallet, computer, or screen. The magnetism can destroy these devices and erase data from cards.

Warning for heart patients

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.

Dust is flammable

Machining of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Respect the power

Be careful. Neodymium magnets attract from a distance and connect with huge force, often faster than you can react.
