Magnetic force weakens sharply per each millimeter of distance. Note that even a microscopic distance (e.g., contamination, paint, veneer) strongly diminishes the holding power. Magnetic products operate most effectively at the point of direct contact; gap nullifies the force. Analyze how quickly the pull force plummet, when the magnet does not touch tightly to the metal substrate. When planning the mounting, avoid redundant distances.

This section presents the approximate force required to start the slippage of the magnet downwards along a upright steel plate (assuming standard friction coefficient). This parameter varies with the air gap between the magnet and the metal.

When hanging a magnet on a vertical surface (e.g., a car body), it will only hold just approx. 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip influence the fact that holders move down faster than they pull off. Planning a wall mount? Consider that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the holder will give way down under a significantly smaller load. Using a rubber pad can drastically increase the grip.

A too thin steel cannot take in the entire magnetic field, which squanders power of the holder. If you install a neodymium to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To achieve 100% of this neodymium's power, you need a suitably thick piece of metal. The saturation phenomenon means that on thin elements (e.g., appliance housings), the holder holds weaker. We recommend selecting the steel dimension according to the table below.

Classic neodymiums lose power after exceeding the maximum temperature. Protect against heat – excessive heat can irreversibly damage this product. With every degree above norm, the neodymium's capacity briefly lowers. Avoid using this product near heat sources higher than its safe range. Too high temperature will cause irreversible degradation of magnetism.
*Important note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low Pc) may lose charge permanently at lower temperatures than long magnets. Red status in the table signals permanent field degradation for this specific geometry.

Two magnetic products interact from a significantly greater distance than a neodymium and metal setup. Such a system of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is huge. The levitation is a bit weaker than the attraction, but still impressive.
*Flux density between like poles reaches ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Figures refer to sliding force of a pair of same magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field is a serious hazard to electronic devices and medical implants. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Remember: the unseen radiation penetrates the body and glass. Exceptional care must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

NdFeB products are prone to chipping – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when playing with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

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

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) significantly limits 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) = 0.74

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.

The offered product is a very strong cylinder magnet, manufactured from durable NdFeB material, which, at dimensions of Ø14x10 mm, guarantees maximum efficiency. This specific item boasts a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 6.71 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
This model is perfect for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 65.83 N with a weight of only 11.55 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.
Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 14.1 mm) using epoxy glues. To ensure stability 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 popular standard for industrial neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø14x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
The presented product is a neodymium magnet with precisely defined parameters: diameter 14 mm and height 10 mm. The value of 65.83 N means that the magnet is capable of holding a weight many times exceeding its own mass of 11.55 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 10 mm), which means that the N and S poles are located on the flat, circular surfaces. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized diametrically if your project requires it.

Pros and cons of rare earth magnets.

Strengths

Besides their high retention, neodymium magnets are valued for these benefits:
  • They have unchanged lifting capacity, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
  • Neodymium magnets prove to be highly resistant to demagnetization caused by external interference,
  • In other words, due to the shiny surface of gold, the element gains a professional look,
  • The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
  • 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 machining as well as adapting to individual conditions,
  • Huge importance in modern technologies – they are used in HDD drives, drive modules, medical equipment, also multitasking production systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Drawbacks and weaknesses of neodymium magnets: application proposals
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
  • Neodymium magnets decrease their power 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 rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Due to limitations in creating threads and complicated shapes in magnets, we recommend using a housing - magnetic mechanism.
  • Possible danger 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 are able to be problematic in diagnostics medical when they are in the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

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

Information about lifting capacity was determined for the most favorable conditions, including:
  • on a base made of mild steel, effectively closing the magnetic flux
  • whose transverse dimension equals approx. 10 mm
  • with a surface free of scratches
  • with direct contact (no coatings)
  • under perpendicular application of breakaway force (90-degree angle)
  • in neutral thermal conditions

Lifting capacity in practice – influencing factors

Bear in mind that the working load may be lower influenced by the following factors, in order of importance:
  • Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
  • Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
  • Material type – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
  • Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
  • Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Safety rules for work with NdFeB magnets
Keep away from computers

Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

Physical harm

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

Shattering risk

Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets will cause them shattering into small pieces.

Safe operation

Handle magnets consciously. Their powerful strength can shock even professionals. Stay alert and respect their force.

Power loss in heat

Do not overheat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).

Warning for heart patients

Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

GPS and phone interference

A strong magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to avoid breaking the sensors.

Allergy Warning

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.

Dust explosion hazard

Mechanical processing of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

This is not a toy

These products are not suitable for play. Eating several magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and necessitates immediate surgery.
