Grip strength weakens significantly per each millimeter of gap. Remember that every additional insulation layer (e.g., dirt, varnish, dust) significantly weakens the grip. Magnetic products operate most effectively in perfect adhesion; distance drastically cuts the power. Notice how quickly the pull force drop, when the product does not touch flatly to the metal substrate. When designing the arrangement, discard additional spacers.

The following data shows the theoretical force needed to cause the shifting of the magnet down on a vertical metal surface (assuming standard friction). This parameter is a function of the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 7x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.30 kg / 0.65 pounds 297.0 g / 2.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.20 kg / 0.44 pounds 198.0 g / 1.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.10 kg / 0.22 pounds 99.0 g / 1.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.50 kg / 1.09 pounds 495.0 g / 4.9 N

When placing a magnet on a upright surface (e.g., a board), it you can count on just approx. 20%-30% of its maximum pull force. Gravitational force and a weak degree of grip cause that magnets slide down faster than they pop off the substrate. Planning a vertical fastening? Remember that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the magnet will slide down under a significantly smaller weight. Application of an anti-slip coating can drastically raise the stability.

A thin sheet cannot conduct the entire magnetic field, which squanders power of the magnet. If you install a neodymium to a too thin substrate, the field will penetrate right through and the holding will be smaller. To squeeze 100% of this neodymium's power, you need a suitably thick element of steel. The material oversaturation causes that on sheet metal structures (e.g., thin profiles), the holder holds weaker. We advise picking the steel dimension according to the table below.

Classic neodymiums irreversibly lose parameters after exceeding the maximum temperature. Watch out for overheating – high temperature can irreversibly destroy this product. As the temperature rises, the neodymium's force momentarily drops. Do not use this product close to ovens exceeding its operating temperature limit. Ignoring the limit will cause permanent loss of magnetism.

*Important note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a neodymium and metal setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of performance. Designing a strong closure? Use a pair of magnets instead of a neodymium and a steel. Remember that when bringing together two magnets, the pinch force is extreme. The repulsion force is a bit weaker than the attraction, but still impressive.
*Field value between like poles drops to ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
* Figures apply to friction force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a serious hazard to electronics and medical implants. These magnets generate a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a strong collision with metal risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum 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 powerful specimens.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

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

2. Steel thickness impact

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

3. Thermal stability

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.39

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 P_c (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 P_c 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 cylinder magnet, produced from advanced NdFeB material, which, at dimensions of Ø7x2 mm, guarantees maximum efficiency. The MW 7x2 / N38 model boasts high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.99 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 9.76 N with a weight of only 0.58 g, this rod is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 7.1 mm) using epoxy glues. To ensure long-term durability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are strong enough for the majority 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 (Ø7x2), 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 Ø7x2 mm, which, at a weight of 0.58 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 0.99 kg (force ~9.76 N), which, with such defined dimensions, proves the high power of the NdFeB material. 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 7 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 through the diameter if your project requires it.

Strengths and weaknesses of neodymium magnets.

Pros

Apart from their strong magnetic energy, neodymium magnets have these key benefits:

Their strength is maintained, and after around ten years it drops only by ~1% (according to research),
Magnets very well defend themselves against loss of magnetization caused by external fields,
In other words, due to the reflective finish of silver, the element gains visual value,
The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
Possibility of accurate creating as well as adjusting to defined conditions,
Versatile presence in modern industrial fields – they find application in computer drives, electric motors, medical devices, also complex engineering applications.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as 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 recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in creating nuts and complicated forms in magnets, we recommend using casing - magnetic mechanism.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
Due to complex production process, their price exceeds standard values,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what contributes to it?

The force parameter is a result of laboratory testing performed under the following configuration:

on a block made of mild steel, effectively closing the magnetic flux
whose thickness is min. 10 mm
with an ideally smooth touching surface
without any air gap between the magnet and steel
under vertical application of breakaway force (90-degree angle)
at ambient temperature room level

Lifting capacity in real conditions – factors

Effective lifting capacity impacted by specific conditions, such as (from most important):

Distance – the presence of any layer (paint, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
Direction of force – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
Surface finish – full contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
Temperature – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.

Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.

H&S for magnets

Bodily injuries

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

Thermal limits

Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.

Eye protection

NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets leads to them shattering into small pieces.

Allergy Warning

Certain individuals experience a contact allergy to Ni, which is the common plating for NdFeB magnets. Prolonged contact can result in skin redness. It is best to use safety gloves.

Choking Hazard

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

Safe operation

Handle with care. Neodymium magnets attract from a distance and snap with huge force, often quicker than you can move away.

GPS and phone interference

GPS units and smartphones are highly sensitive to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.

Life threat

For implant holders: Powerful magnets disrupt electronics. Keep at least 30 cm distance or ask another person to work with the magnets.

Machining danger

Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Data carriers

Do not bring magnets close to a purse, computer, or screen. The magnetic field can destroy these devices and erase data from cards.

Danger! More info about hazards in the article: Safety of working with magnets.
