Grip strength weakens drastically with every subsequent millimeter of distance. Remember that every additional insulation layer (e.g., dirt, paint, rust) strongly weakens the grip. Magnetic products work optimally in perfect adhesion; air break nullifies the power. See how flashily the load capacity fall, when the product does not adhere tightly to the metal substrate. When planning the mounting, discard redundant distances.

When mounting a holder on a upright surface (e.g., a car body), it will maintain only about 20%-30% of its maximum pull force. Gravitational force as well as a weak degree of grip mean that holders slide down faster than they pull off. Planning a hanger? Note that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the magnet will give way down under a significantly smaller weight. Application of an anti-slip pad can significantly improve the result.

A too thin steel is incapable of take in the entire magnetic field, which weakens actual performance of the holder. Should you mount a strong magnet to a weak sheet, the field will penetrate right through and the pull force will drop sharply. To utilize the maximum of this magnet's power, you need a suitably thick backing of metal. The material oversaturation causes that on sheet metal structures (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel thickness based on the following data.

Ordinary NdFeB products lose parameters above the temperature limit. Protect against heat – high temperature can permanently demagnetize this product. With every degree above norm, the neodymium's capacity briefly lowers. Refrain from using this magnet close to heaters exceeding its operating temperature limit. Too high temperature will cause irreversible degradation of magnetic properties.
*Important note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than long magnets. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnets attract each other from a much further distance than a neodymium and metal combination. The connection of magnet-to-magnet produces a massive flux and a wider radius of performance. Designing a strong closure? Use a pair of magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the pinch force is massive. The levitation is slightly lower than the connection force, but still impressive.
*The magnetic induction between like poles is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).
Note: Calculations show sliding force of two same magnets (friction ~0.15 for Ni-Ni layer).

Neodymium magnets are delicate – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or injury to skin. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

1. Sliding resistance

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

2. Steel thickness impact

*Thin steel (e.g. computer case) drastically reduces the holding force.

3. Power loss vs temp

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.63

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 incredibly powerful rod magnet, composed of advanced NdFeB material, which, at dimensions of Ø45x25 mm, guarantees optimal power. This specific item is characterized by an accuracy of ±0.1mm and professional build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 67.33 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is created for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 660.51 N with a weight of only 298.21 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 45.1 mm) using epoxy glues. To ensure long-term durability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most frequently chosen standard for professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø45x25), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 45 mm and height 25 mm. The key parameter here is the lifting capacity amounting to approximately 67.33 kg (force ~660.51 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 45 mm. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized diametrically if your project requires it.

Pros and cons of rare earth magnets.

Strengths

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They retain attractive force for almost 10 years – the loss is just ~1% (according to analyses),
  • Magnets effectively resist against demagnetization caused by external fields,
  • By using a shiny layer of gold, the element has an modern look,
  • Neodymium magnets ensure maximum magnetic induction on a small surface, which allows for strong attraction,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
  • Possibility of exact modeling as well as modifying to individual needs,
  • Fundamental importance in modern technologies – they are utilized in computer drives, brushless drives, medical devices, as well as industrial machines.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Weaknesses

Characteristics of disadvantages of neodymium magnets and ways of using them
  • At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Neodymium magnets decrease 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 durability even at temperatures up to 230°C
  • Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
  • Limited ability of producing nuts in the magnet and complex forms - recommended is casing - mounting mechanism.
  • Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, small elements of these products can disrupt the diagnostic process medical in case of swallowing.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what it depends on?

Breakaway force was determined for optimal configuration, taking into account:
  • on a block made of mild steel, optimally conducting the magnetic field
  • possessing a thickness of minimum 10 mm to avoid saturation
  • with a surface free of scratches
  • under conditions of ideal adhesion (surface-to-surface)
  • under axial application of breakaway force (90-degree angle)
  • at conditions approx. 20°C

Lifting capacity in practice – influencing factors

In practice, the actual lifting capacity results from a number of factors, presented from the most important:
  • Air gap (betwixt the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
  • Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
  • Metal type – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
  • Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
  • Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.

Safe handling of neodymium magnets
Keep away from children

Always keep magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are very dangerous.

Machining danger

Dust generated during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Impact on smartphones

Note: neodymium magnets produce a field that disrupts sensitive sensors. Keep a separation from your phone, device, and GPS.

Safe operation

Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can react.

Permanent damage

Keep cool. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Keep away from computers

Avoid bringing magnets close to a wallet, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.

Bone fractures

Mind your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Risk of cracking

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Skin irritation risks

Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and use protective gear.

Life threat

Warning for patients: Powerful magnets affect electronics. Keep minimum 30 cm distance or request help to work with the magnets.
