Pulling power weakens sharply with every subsequent millimeter of gap. Remember that even the smallest gap (e.g., contamination, paint, dust) significantly reduces the pull force. Magnetic products hold strongest in perfect adhesion; gap nullifies the force. Notice how flashily the load capacity drop, when the product does not touch flatly to the metal substrate. When calculating the arrangement, eliminate redundant distances.

When placing a element on a upright surface (e.g., a fridge), it will maintain just approx. 1/5 of nominal attraction strength. Gravity and a weak degree of grip influence the fact that holders slide down easier than they pull off. Planning a hanger? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a significantly smaller cargo. Utilizing a rubberized layer can drastically increase the grip.

A thin metal plate is unable to take in the full magnetic flux, which weakens actual performance of the holder. Should you install a neodymium to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To utilize 100% of this magnet's potential, you require a sufficiently solid piece of metal. The saturation effect means that on thin elements (e.g., thin profiles), the product shows lower pull force. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets change their properties strength after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently demagnetize this magnet. With increasing heat, the magnet's capacity temporarily lowers. Do not use this magnet in hot environments higher than its safe range. Ignoring the limit will result in destruction of magnetism.
*Technical advisory: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low Pc) may lose charge permanently under lower heat stress than taller cylinders. Red status in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and steel combination. The connection of two magnets creates a more powerful interaction and a larger range of operation. Planning to create a strong closure? Apply two magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the collision energy is extreme. The repulsion force is marginally weaker than the attraction, but still significant.
*Field value between like poles reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Important: Results show friction force of dual same neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to electronic devices as well as pacemakers. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field acts through matter and glass. Exceptional care must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or injury to skin. Be sure to control the product during bringing near metal 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. Use safety goggles when handling with large magnets.

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.
In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.
1. Vertical hold

*Note: On a vertical wall, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) significantly weakens the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.22

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.

This product is an exceptionally strong cylindrical magnet, manufactured from durable NdFeB material, which, with dimensions of Ø10x1.5 mm, guarantees optimal power. The MW 10x1.5 / N38 component boasts a tolerance of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 0.82 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating secures 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 filters, where field concentration on a small surface counts. Thanks to the pull force of 8.01 N with a weight of only 0.88 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.
Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure stability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Magnets NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø10x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.
This model is characterized by dimensions Ø10x1.5 mm, which, at a weight of 0.88 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 0.82 kg (force ~8.01 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.
This cylinder is magnetized axially (along the height of 1.5 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.

Strengths as well as weaknesses of Nd2Fe14B magnets.

Advantages

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
  • They feature excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
  • In other words, due to the aesthetic layer of gold, the element gains a professional look,
  • Neodymium magnets achieve maximum magnetic induction on a small surface, which increases force concentration,
  • Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
  • Thanks to versatility in forming and the capacity to customize to client solutions,
  • Huge importance in modern technologies – they are commonly used in data components, electromotive mechanisms, medical equipment, as well as multitasking production systems.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Disadvantages

What to avoid - cons 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 secures them against impacts but also increases their durability
  • Neodymium magnets lose 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 stability even at temperatures up to 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
  • We suggest cover - magnetic holder, due to difficulties in creating threads inside the magnet and complicated forms.
  • Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products 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

Lifting parameters

Highest magnetic holding force – what contributes to it?

The force parameter is a measurement result executed under specific, ideal conditions:
  • on a block made of mild steel, optimally conducting the magnetic flux
  • with a thickness minimum 10 mm
  • characterized by lack of roughness
  • under conditions of ideal adhesion (surface-to-surface)
  • under axial force direction (90-degree angle)
  • in stable room temperature

Lifting capacity in real conditions – factors

In real-world applications, the actual lifting capacity depends on several key aspects, listed from most significant:
  • Gap (betwixt the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
  • Angle of force application – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
  • Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
  • Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
  • Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.

H&S for magnets
ICD Warning

Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Mechanical processing

Powder produced during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Pinching danger

Danger of trauma: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.

Nickel allergy

Some people have a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Extended handling may cause a rash. We recommend use protective gloves.

Power loss in heat

Keep cool. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).

Swallowing risk

Product intended for adults. Small elements can be swallowed, causing severe trauma. Keep away from kids and pets.

Cards and drives

Do not bring magnets close to a purse, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Phone sensors

Note: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, device, and GPS.

Magnets are brittle

Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Safe operation

Use magnets consciously. Their immense force can surprise even experienced users. Be vigilant and do not underestimate their power.
