Grip strength drops drastically per each millimeter of gap. Remember that even the smallest gap (e.g., contamination, paint, dust) strongly weakens the grip. Neodymiums work optimally at the point of direct contact; gap kills the force. Notice how flashily the pull force drop, when the product does not adhere tightly to the steel surface. When planning the arrangement, eliminate redundant distances.

The following data defines the estimated force required to start the downward movement of the magnet down on a vertical steel plate (considering typical friction coefficient). This value is relative to the gap size between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 10x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.25 kg / 0.54 pounds 246.0 g / 2.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.16 kg / 0.36 pounds 164.0 g / 1.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.18 pounds 82.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.41 kg / 0.90 pounds 410.0 g / 4.0 N

When hanging a magnet on a vertical wall (e.g., a fridge), it will only hold just approx. 20%-30% of its nominal power. Gravity as well as a low friction coefficient cause that holders slide down easier than they detach. Want to create a hanger? Consider that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the element will give way down under a noticeably lighter cargo. Using a rubber layer can drastically increase the grip.

A thin sheet is incapable of take in the entire magnetic field, which wastes potential of the holder. Should you mount a strong magnet to a weak sheet, the field will pass right through and the pull force will drop sharply. To utilize 100% of this neodymium's potential, you require a sufficiently solid piece of steel. The saturation effect causes that on sheet metal structures (e.g., car bodies), the product works worse. We suggest choosing the steel dimension based on the following data.

Table 5: Thermal resistance (stability) - resistance threshold

40 °C	-2.2%	0.80 kg / 1.77 pounds 802.0 g / 7.9 N	OK

100 °C	-28.8%	0.58 kg / 1.29 pounds 583.8 g / 5.7 N

Standard neodymium magnets change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – heat can irreversibly demagnetize this magnet. With increasing heat, the neodymium's capacity momentarily lowers. Avoid using this product in hot environments higher than its working range. Too high temperature will result in irreversible degradation of magnetic properties.

*Engineering note: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low Pc) are more susceptible to demagnetization at lower temperatures than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet combination. The setup of two magnets produces a massive flux and a wider radius of action. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the impact force is extreme. The repulsion force is a bit weaker 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: Calculations apply to friction force of dual identical magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a real danger to electronics as well as medical implants. These neodymiums produce a flux that destroys function of digital equipment. Be aware: the invisible magnetic field acts through matter and glass. Special caution must be taken by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - warning

Magnetic elements are delicate – a collision with steel can result in shattering. Control the attraction moment – a neodymium left loose turns into a projectile. Striking energy can cause material chips or dangerous crushing to skin. Be sure to control the product during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear eye protection when handling with powerful specimens.

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. Buoyancy helps in lifting finds.

1. Vertical hold

*Caution: On a vertical wall, the magnet retains only approx. 20-30% of its nominal pull.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) severely weakens 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) = 0.22

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.

16.64 ZŁ brutto / pcs

This product is a very strong rod magnet, made from modern NdFeB material, which, with dimensions of Ø10x1.5 mm, guarantees optimal power. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.82 kg), this product is in stock from our warehouse in Poland, ensuring quick 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.

It finds application in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 8.01 N with a weight of only 0.88 g, this rod 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., 10.1 mm) using two-component epoxy glues. To ensure long-term durability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are suitable for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø10x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 1.5 mm. The value of 8.01 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.88 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 1.5 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Strengths

Besides their stability, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
Magnets effectively defend themselves against loss of magnetization caused by foreign field sources,
In other words, due to the aesthetic surface of gold, the element gains a professional look,
Magnets are distinguished by very high magnetic induction on the working surface,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Thanks to versatility in shaping and the ability to modify to individual projects,
Fundamental importance in high-tech industry – they find application in magnetic memories, electric motors, diagnostic systems, and industrial machines.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited ability of producing threads in the magnet and complex forms - preferred is a housing - mounting mechanism.
Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Furthermore, small elements of these devices can be problematic in diagnostics medical when they are in the body.
With budget limitations the cost of neodymium magnets is economically unviable,

Pull force analysis

Highest magnetic holding force – what affects it?

The lifting capacity listed is a result of laboratory testing performed under standard conditions:

on a plate made of structural steel, optimally conducting the magnetic flux
whose thickness is min. 10 mm
with a plane perfectly flat
with total lack of distance (no impurities)
for force applied at a right angle (pull-off, not shear)
in neutral thermal conditions

Determinants of lifting force in real conditions

Bear in mind that the magnet holding will differ influenced by elements below, starting with the most relevant:

Gap between surfaces – 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.
Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
Plate thickness – too thin plate causes magnetic saturation, causing part of the power to be wasted to the other side.
Material type – the best choice is pure iron steel. Cast iron may attract less.
Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets

Immense force

Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Heat sensitivity

Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.

Threat to navigation

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

Do not drill into magnets

Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Swallowing risk

Adult use only. Small elements pose a choking risk, leading to severe trauma. Keep away from children and animals.

Medical interference

For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Avoid contact if allergic

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop handling magnets and use protective gear.

Beware of splinters

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

Crushing risk

Watch your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!

Cards and drives

Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
