Pulling power weakens drastically with every mm of distance. Remember that every additional insulation layer (e.g., dirt, paint, dust) strongly reduces the pull force. Magnets operate strongest during direct contact; air break kills the power. Analyze how flashily the pull force plummet, when the product does not touch directly to the steel surface. When calculating the mounting, discard additional spacers.

This section indicates the theoretical weight limit needed to initiate the slippage of the magnet downwards along a upright metal surface (assuming typical friction coefficient). The holding force is a function of the air gap between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 5x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.14 kg / 0.30 pounds 135.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 pounds 90.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 pounds 45.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.50 pounds 225.0 g / 2.2 N

When placing a element on a upright wall (e.g., a fridge), it will maintain barely approx. 20%-30% of its nominal power. Gravitational force as well as a low friction coefficient influence the fact that products slip easier than they pull off. Designing a vertical fastening? Note that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the element will give way down under a significantly smaller weight. Utilizing a rubberized coating can drastically increase the grip.

12 mm	100%	0.45 kg / 0.99 pounds 450.0 g / 4.4 N

A thin sheet is unable to take in the entire magnetic field, which wastes potential of the magnet. If you attach a powerful product to a thin surface, the field will penetrate right through and the holding will be smaller. To utilize 100% of this neodymium's power, you need a suitably thick backing of steel. The saturation effect causes that on sheet metal structures (e.g., car bodies), the product works worse. We advise picking the steel thickness from these parameters.

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly demagnetize this product. With increasing heat, the neodymium's capacity briefly drops. Avoid using this magnet close to ovens higher than its working range. Ignoring the limit will lead to irreversible degradation of magnetic properties.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Flat magnets (low Pc) are more susceptible to demagnetization sooner compared to rod magnets. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal setup. The connection of magnet-to-magnet generates a stronger field and a larger range of performance. Want to build a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the pinch force is massive. The levitation is a bit weaker than the connection force, but still impressive.
*Field value for N-N configuration drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Figures show shear force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a large risk to electronics as well as pacemakers. These NdFeB products generate a flux that destroys function of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and glass. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Neodymium magnets are prone to chipping – a strong collision with metal risks their cracking. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can destroy the magnet or injury to fingers. Be sure to control the product during installation so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the neodymium. Use safety goggles when working with large magnets.

Corrosion warning: 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. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

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

2. Steel saturation

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.59

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 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.

MW 10x2 / N38 - cylindrical magnet

0.467 zł brutto / pcs

This product is an extremely powerful cylinder magnet, made from advanced NdFeB material, which, with dimensions of Ø5x30 mm, guarantees maximum efficiency. This specific item features high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.45 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields 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 filters, where field concentration on a small surface counts. Thanks to the high power of 4.40 N with a weight of only 4.42 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, 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 professional neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø5x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 5 mm and height 30 mm. The key parameter here is the lifting capacity amounting to approximately 0.45 kg (force ~4.40 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 oxidation, 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 5 mm. Such an arrangement is most desirable 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 through the diameter if your project requires it.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Benefits

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They do not lose strength, even during approximately 10 years – the decrease in power is only ~1% (based on measurements),
They are resistant to demagnetization induced by external field influence,
The use of an refined layer of noble metals (nickel, gold, silver) causes the element to look better,
Magnetic induction on the surface of the magnet remains exceptional,
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...
Thanks to versatility in designing and the capacity to adapt to unusual requirements,
Versatile presence in electronics industry – they find application in mass storage devices, motor assemblies, precision medical tools, as well as multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Drawbacks and weaknesses of neodymium magnets and proposals for their use:

At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
We suggest casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices can complicate diagnosis medical after entering the body.
Due to expensive raw materials, their price is relatively high,

Pull force analysis

Magnetic strength at its maximum – what it depends on?

Holding force of 0.45 kg is a theoretical maximum value performed under standard conditions:

on a block made of mild steel, effectively closing the magnetic field
possessing a thickness of at least 10 mm to ensure full flux closure
with a plane perfectly flat
without the slightest insulating layer between the magnet and steel
under vertical application of breakaway force (90-degree angle)
at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

In practice, the actual lifting capacity results from several key aspects, ranked from crucial:

Gap (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic properties and lifting capacity.
Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity was measured with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.

Safety rules for work with neodymium magnets

Finger safety

Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!

Protective goggles

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Danger to pacemakers

For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.

Conscious usage

Handle magnets consciously. Their huge power can shock even experienced users. Plan your moves and respect their power.

Threat to electronics

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

Dust is flammable

Machining of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Avoid contact if allergic

Certain individuals suffer from a hypersensitivity to nickel, which is the common plating for neodymium magnets. Frequent touching may cause skin redness. We recommend use protective gloves.

GPS and phone interference

A powerful magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Keep magnets close to a device to avoid damaging the sensors.

Do not give to children

Strictly store magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are tragic.

Heat warning

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