Magnetic force weakens drastically per each millimeter of spacing. Remember that even a microscopic distance (e.g., dirt, varnish, rust) noticeably weakens the grip. Magnetic products hold most effectively in perfect adhesion; air break kills the power. Analyze how rapidly the parameters plummet, when the magnet does not touch directly to the steel surface. When planning the mounting, eliminate redundant distances.

The following data calculates the estimated holding capacity sufficient to initiate the slippage of the magnet down against a vertical steel wall (considering typical friction coefficient). This parameter depends on the distance between the magnet and the metal.

When mounting a magnet on a vertical plane (e.g., a fridge), it will only hold just approx. 1/5 of its maximum pull force. Gravitational force and a low friction coefficient mean that products move down faster than they detach. Designing a wall mount? Consider that the shear force is significantly lower than the maximum static pull force. On a slippery surface, the element will give way down under a significantly smaller load. Utilizing a rubberized layer can effectively increase the grip.

A thin metal plate is incapable of conduct the entire magnetic field, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the field will pass right through and the attraction force will be weaker. To achieve the maximum of this magnet's power, you need a suitably thick piece of steel. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the magnet shows lower pull force. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products change their properties power above the temperature limit. Avoid high temperatures – high temperature can irreversibly demagnetize this magnet. With every degree above norm, the magnet's force momentarily lowers. Avoid using this product near heat sources exceeding its operating temperature limit. Exceeding the critical threshold will result in destruction of magnetism.
*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (pancake types) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table signals permanent field degradation for this particular item.

Two strong neodymiums interact from a much further distance than a magnet and steel combination. The setup of two magnets generates a stronger field and a wider radius of action. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a steel. Be careful that when bringing together two magnets, the impact force is massive. The repulsion force is marginally weaker than the attraction, but still significant.
*Field value between like poles drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Estimates refer to friction force of dual matching magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field is a serious hazard to electronics as well as medical implants. These neodymiums produce a flux that disrupts operation of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and glass. Special caution must be taken by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a strong collision with metal risks their cracking. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or dangerous crushing to fingers. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when playing with powerful specimens.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.
1. Wall mount (shear)

*Warning: On a vertical wall, the magnet holds merely approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) drastically 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.

This product is a very strong cylindrical magnet, composed of durable NdFeB material, which, at dimensions of Ø35x5 mm, guarantees maximum efficiency. The MW 35x5 / N38 model features high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 9.25 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is perfect for building generators, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 90.73 N with a weight of only 36.08 g, this cylindrical magnet is indispensable in electronics 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., 35.1 mm) using epoxy glues. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.
Magnets NdFeB grade N38 are suitable for 90% of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø35x5), 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 Ø35x5 mm, which, at a weight of 36.08 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 9.25 kg (force ~90.73 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.
This cylinder is magnetized axially (along the height of 5 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.

Pros and cons of rare earth magnets.

Pros

Apart from their strong power, neodymium magnets have these key benefits:
  • They do not lose strength, even after approximately ten years – the drop in strength is only ~1% (theoretically),
  • Neodymium magnets are characterized by remarkably resistant to magnetic field loss caused by external interference,
  • The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to flexibility in forming and the ability to customize to client solutions,
  • Universal use in innovative solutions – they serve a role in HDD drives, electric drive systems, diagnostic systems, also modern systems.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Drawbacks and weaknesses of neodymium magnets and ways of using them
  • To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
  • Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
  • Due to limitations in producing nuts and complicated shapes in magnets, we recommend using casing - magnetic mount.
  • Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

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

The load parameter shown concerns the maximum value, obtained under ideal test conditions, specifically:
  • with the contact of a yoke made of special test steel, ensuring full magnetic saturation
  • whose transverse dimension equals approx. 10 mm
  • with a surface cleaned and smooth
  • under conditions of no distance (metal-to-metal)
  • during pulling in a direction perpendicular to the mounting surface
  • at ambient temperature room level

Magnet lifting force in use – key factors

During everyday use, the real power results from many variables, presented from the most important:
  • Distance – the presence of any layer (rust, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
  • Load vector – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
  • Base massiveness – too thin sheet causes magnetic saturation, causing part of the flux to be escaped into the air.
  • Steel type – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
  • Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
  • Heat – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.

Warnings
Life threat

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Compass and GPS

Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.

Electronic hazard

Device Safety: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).

Conscious usage

Handle magnets with awareness. Their powerful strength can surprise even professionals. Plan your moves and respect their force.

Crushing risk

Large magnets can break fingers instantly. Never put your hand betwixt two attracting surfaces.

Warning for allergy sufferers

Studies show that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands or select encased magnets.

Heat sensitivity

Control the heat. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.

Machining danger

Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Shattering risk

Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Keep away from children

Neodymium magnets are not intended for children. Swallowing multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
