Magnetic force drops significantly with every subsequent millimeter of gap. Remember that even the smallest gap (e.g., dirt, paint, dust) strongly reduces the pull force. Magnetic products work strongest during direct contact; air break nullifies the force. Analyze how quickly the load capacity drop, when the product does not adhere tightly to the metal substrate. When planning the arrangement, avoid additional spacers.

This section calculates the approximate shear load necessary to initiate the slippage of the magnet downwards along a vertical steel wall (considering typical friction). This value is a function of the distance between the magnet and the surface.

When hanging a holder on a upright surface (e.g., a fridge), it you can count on barely about 1/5 of its nominal power. Gravity and a weak degree of grip influence the fact that magnets slip faster than they pull off. Planning a vertical fastening? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a noticeably lighter load. Using a rubber coating can drastically improve the result.

A thin metal plate cannot conduct the entire magnetic field, which wastes potential of the holder. Should you install a neodymium to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To squeeze 100% of this magnet's potential, you need a suitably thick backing of metal. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the holder holds weaker. We advise picking the steel thickness based on the following data.

Standard neodymium magnets change their properties strength above the temperature limit. Protect against heat – high temperature can irreversibly destroy this product. With increasing heat, the neodymium's capacity momentarily decreases. Refrain from using this product close to ovens higher than its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.
*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) risk losing magnetic properties sooner than taller cylinders. Red status in the table indicates permanent field degradation for this particular item.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets produces a massive flux and a wider radius of action. Designing a powerful holder? Use a pair of magnets instead of one magnet and a steel. Remember that when bringing together two magnets, the impact force is massive. The levitation is slightly lower than the connection force, but still significant.
*Flux density between like poles reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
* Calculations demonstrate shear force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a serious hazard to electronics as well as pacemakers. These neodymiums produce a field that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field acts through matter and glass. Exceptional care must be taken by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or dangerous crushing to skin. Always hold the magnet during mounting so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the magnet. Wear safety glasses when handling with powerful specimens.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Caution: On a vertical wall, the magnet retains merely approx. 20-30% of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) drastically limits the holding force.

3. Temperature resistance

*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) = 0.63

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 incredibly powerful rod magnet, composed of durable NdFeB material, which, at dimensions of Ø18x10 mm, guarantees optimal power. The MW 18x10 / N38 component features an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 10.76 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 105.51 N with a weight of only 19.09 g, this rod is indispensable in miniature devices and wherever every gram matters.
Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure stability in automation, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Magnets N38 are strong enough for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø18x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.
This model is characterized by dimensions Ø18x10 mm, which, at a weight of 19.09 g, makes it an element with impressive magnetic energy density. The value of 105.51 N means that the magnet is capable of holding a weight many times exceeding its own mass of 19.09 g. 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 18 mm. 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.

Advantages and disadvantages of neodymium magnets.

Benefits

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:
  • They have stable power, and over around 10 years their performance decreases symbolically – ~1% (in testing),
  • Magnets perfectly defend themselves against loss of magnetization caused by external fields,
  • The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to look better,
  • They show high magnetic induction at the operating surface, making them more effective,
  • 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...
  • In view of the potential of accurate forming and customization to unique needs, magnetic components can be manufactured in a wide range of shapes and sizes, which increases their versatility,
  • Wide application in modern industrial fields – they serve a role in hard drives, motor assemblies, advanced medical instruments, and other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems

Weaknesses

Disadvantages of NdFeB magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
  • NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Due to limitations in creating nuts and complex shapes in magnets, we propose using casing - magnetic mechanism.
  • Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Additionally, tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Breakaway strength of the magnet in ideal conditions – what it depends on?

The force parameter is a theoretical maximum value performed under specific, ideal conditions:
  • with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
  • with a cross-section of at least 10 mm
  • with an ideally smooth touching surface
  • with direct contact (without impurities)
  • during pulling in a direction vertical to the plane
  • in neutral thermal conditions

Lifting capacity in real conditions – factors

Bear in mind that the magnet holding will differ influenced by elements below, in order of importance:
  • Distance (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
  • Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
  • Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Material type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
  • Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
  • Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

Safety rules for work with neodymium magnets
Nickel coating and allergies

Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from direct skin contact and select encased magnets.

Life threat

Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Heat sensitivity

Control the heat. Exposing the magnet to high heat will permanently weaken its magnetic structure and pulling force.

Combustion hazard

Dust created during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Threat to electronics

Do not bring magnets close to a purse, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.

Respect the power

Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.

Hand protection

Danger of trauma: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.

Product not for children

Product intended for adults. Small elements can be swallowed, leading to serious injuries. Store out of reach of children and animals.

Phone sensors

A powerful magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to avoid damaging the sensors.

Beware of splinters

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
