Pulling power decreases sharply with every subsequent millimeter of spacing. Keep in mind that even a very thin break (e.g., dirt, varnish, dust) noticeably reduces the pull force. Magnets operate optimally at the point of direct contact; air break drastically cuts the power. See how rapidly the pull force plummet, when the magnet does not touch flatly to the steel surface. When calculating the arrangement, eliminate redundant distances.

This section shows the approximate force necessary to start the downward movement of the magnet downwards on a upright steel wall (assuming typical friction). The holding force depends on the distance between the magnet and the metal.

When placing a holder on a vertical wall (e.g., a fridge), it you can count on only approx. 20%-30% of nominal attraction strength. Gravity as well as a low friction coefficient cause that holders slide down faster than they pull off. Planning a wall mount? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will give way down under a much lighter load. Using a rubber coating can significantly increase the grip.

A thin metal plate cannot absorb the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To utilize the maximum of this magnet's potential, you need a suitably thick element of steel. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the magnet works worse. We advise picking the steel thickness according to the table below.

Standard neodymium magnets lose strength above the temperature limit. Protect against heat – high temperature can permanently destroy this product. With every degree above norm, the neodymium's capacity momentarily decreases. Do not use this magnet near heat sources exceeding its safe range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.
*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) are more susceptible to demagnetization sooner than taller cylinders. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a much further distance than a magnet and steel setup. The connection of two magnets creates a more powerful interaction and a further horizon of action. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still large.
*The magnetic induction in repulsion mode drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Important: Results demonstrate shear force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a large risk to electronics as well as medical implants. These neodymiums generate a flux that destroys function of digital equipment. Be aware: the invisible magnetic field penetrates the body and plastic. Special caution must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Magnetic elements are very brittle – a violent impact against metal risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can cause material chips or injury to fingers. Be sure to control the product during installation so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when handling with large magnets.

1. Wall mount (shear)

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

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) significantly weakens the holding force.

3. Heat tolerance

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

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

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

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 presented product is an incredibly powerful rod magnet, composed of modern NdFeB material, which, with dimensions of Ø14x2 mm, guarantees the highest energy density. The MW 14x2 / N38 model is characterized by high dimensional repeatability and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 1.48 kg), this product is in stock from our European logistics center, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 14.51 N with a weight of only 2.31 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.
Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 14.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø14x2), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 14 mm and height 2 mm. The key parameter here is the holding force amounting to approximately 1.48 kg (force ~14.51 N), which, with such defined dimensions, proves the high grade of the NdFeB material. 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 2 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Strengths as well as weaknesses of neodymium magnets.

Strengths

Besides their high retention, neodymium magnets are valued for these benefits:
  • Their magnetic field remains stable, and after around ten years it drops only by ~1% (theoretically),
  • They have excellent resistance to magnetic field loss due to external fields,
  • The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
  • They feature high magnetic induction at the operating surface, which improves attraction properties,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
  • Due to the possibility of precise forming and customization to specialized projects, magnetic components can be created in a wide range of geometric configurations, which expands the range of possible applications,
  • Significant place in modern industrial fields – they serve a role in computer drives, drive modules, diagnostic systems, and 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

Limitations

What to avoid - cons of neodymium magnets and proposals for their use:
  • At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
  • Limited possibility of creating nuts in the magnet and complex forms - preferred is casing - magnetic holder.
  • Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical in case of swallowing.
  • With large orders the cost of neodymium magnets is economically unviable,

Lifting parameters

Maximum lifting capacity of the magnet – what affects it?

The force parameter is a measurement result performed under the following configuration:
  • with the contact of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
  • with a thickness of at least 10 mm
  • with an ground touching surface
  • under conditions of gap-free contact (metal-to-metal)
  • during detachment in a direction vertical to the plane
  • at room temperature

Determinants of practical lifting force of a magnet

Holding efficiency is influenced by specific conditions, mainly (from most important):
  • Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
  • Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be escaped to the other side.
  • Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
  • Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
  • Thermal environment – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Safety rules for work with neodymium magnets
Demagnetization risk

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Crushing force

Danger of trauma: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.

Precision electronics

A strong magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Keep magnets close to a smartphone to avoid damaging the sensors.

Handling guide

Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.

No play value

Strictly store magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are fatal.

Electronic devices

Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).

Material brittleness

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

Allergy Warning

Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness occurs, cease working with magnets and wear gloves.

Life threat

For implant holders: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.

Dust explosion hazard

Dust created during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
