1. Sliding resistance

*Warning: On a vertical wall, the magnet retains merely approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) drastically weakens 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) = 0.26

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.

Magnet pull force

Field Strength

Component MPL 60x10x5 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 18.16 kg), this product is available off-the-shelf 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 18.16 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.
They constitute a key element in the production of wind generators and material handling systems. Thanks to the flat surface and high force (approx. 18.16 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.
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 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. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.
This model is characterized by dimensions 60x10x5 mm, which, at a weight of 22.5 g, makes it an element with high 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 protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of Nd2Fe14B magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:
  • They retain full power for around 10 years – the loss is just ~1% (according to analyses),
  • They possess excellent resistance to magnetism drop due to opposing magnetic fields,
  • Thanks to the elegant finish, the layer of nickel, gold, or silver-plated gives an aesthetic appearance,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
  • Thanks to freedom in shaping and the ability to modify to unusual requirements,
  • Fundamental importance in innovative solutions – they find application in hard drives, motor assemblies, diagnostic systems, as well as industrial machines.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in miniature devices

Disadvantages

Cons of neodymium magnets: weaknesses and usage 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 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 advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
  • Due to limitations in realizing threads and complicated forms in magnets, we propose using casing - magnetic holder.
  • Potential hazard resulting from small fragments of magnets can be dangerous, 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 devices can complicate diagnosis medical after entering the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Optimal lifting capacity of a neodymium magnetwhat affects it?

Magnet power is the result of a measurement for optimal configuration, taking into account:
  • with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
  • whose transverse dimension is min. 10 mm
  • with an ideally smooth touching surface
  • without any clearance between the magnet and steel
  • during detachment in a direction vertical to the mounting surface
  • in temp. approx. 20°C

What influences lifting capacity in practice

Effective lifting capacity impacted by working environment parameters, including (from most important):
  • Gap (between the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, rust or debris).
  • Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
  • Plate thickness – too thin plate does not close the flux, causing part of the flux to be wasted into the air.
  • Material type – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
  • Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
  • Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

Safe handling of neodymium magnets
Hand protection

Big blocks can break fingers instantly. Never place your hand between two attracting surfaces.

Heat sensitivity

Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.

Magnetic media

Data protection: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).

Fragile material

Neodymium magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets will cause them shattering into small pieces.

Allergic reactions

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.

Do not give to children

Always keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are tragic.

Precision electronics

GPS units and mobile phones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Dust is flammable

Powder created during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Pacemakers

Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Safe operation

Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
