Magnetic force decreases significantly with every subsequent millimeter of spacing. Remember that every additional insulation layer (e.g., dirt, varnish, veneer) strongly diminishes the holding power. Magnetic products work strongest at the point of direct contact; air break weakens the power. Notice how rapidly the load capacity plummet, when the magnet does not touch flatly to the steel surface. When designing the assembly, avoid redundant distances.

The following data indicates the approximate holding capacity necessary to start the slippage of the magnet down along a vertical steel plate (considering typical friction coefficient). This value varies with the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MW 12x50 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.79 kg / 1.73 lbs 786.0 g / 7.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.52 kg / 1.16 lbs 524.0 g / 5.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.26 kg / 0.58 lbs 262.0 g / 2.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.31 kg / 2.89 lbs 1310.0 g / 12.9 N

When placing a magnet on a upright plane (e.g., a board), it will only hold just about 1/5 of its nominal power. Gravity as well as a weak degree of grip influence the fact that holders slide down easier than they detach. Want to create a hanger? Remember that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the element will slip down under a significantly smaller load. Application of an anti-slip coating can drastically raise the stability.

A thin sheet is incapable of conduct the entire magnetic field, which squanders power of the holder. Should you mount a strong magnet to a too thin substrate, the field will pass right through and the pull force will drop sharply. To utilize 100% of this magnet's potential, you require a sufficiently solid backing of metal. The saturation phenomenon causes that on sheet metal structures (e.g., appliance housings), the product works worse. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products change their properties power past the thermal threshold. Protect against heat – heat can irreversibly destroy this magnet. With every degree above norm, the magnet's force briefly decreases. Do not use this magnet close to heaters higher than its working range. Ignoring the limit will lead to permanent loss of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) may lose charge permanently sooner compared to rod magnets. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a much further distance than a magnet and steel combination. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of performance. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the impact force is massive. The repulsion force is a bit weaker than the connection force, but still significant.
*The magnetic induction between like poles is approximately ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Note: Results show sliding force of two matching magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to electronics and pacemakers. These NdFeB products produce a flux that disrupts operation of digital equipment. Be aware: the invisible magnetic field penetrates the body and plastic. Special caution must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are very brittle – a collision with steel risks their cracking. Control the attraction moment – a neodymium left loose speeds with massive force. Impact energy can trigger coating fragments or injury to fingers. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Caution: On a vertical surface, the magnet retains just a fraction of its perpendicular strength.

2. Steel saturation

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

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.49

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.

The offered product is an extremely powerful cylindrical magnet, made from durable NdFeB material, which, at dimensions of Ø12x50 mm, guarantees optimal power. This specific item boasts a tolerance of ±0.1mm and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 2.62 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 25.73 N with a weight of only 42.41 g, this cylindrical magnet is indispensable in electronics 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., 12.1 mm) using epoxy glues. To ensure stability in automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø12x50), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 12 mm and height 50 mm. The value of 25.73 N means that the magnet is capable of holding a weight many times exceeding its own mass of 42.41 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 50 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.

Pros as well as cons of rare earth magnets.

Pros

Besides their exceptional strength, neodymium magnets offer the following advantages:

They retain full power for nearly 10 years – the loss is just ~1% (according to analyses),
They feature excellent resistance to magnetic field loss when exposed to external fields,
Thanks to the shiny finish, the surface of nickel, gold-plated, or silver gives an aesthetic appearance,
Magnets are distinguished by extremely high magnetic induction on the active area,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Thanks to freedom in forming and the ability to adapt to specific needs,
Universal use in future technologies – they find application in computer drives, drive modules, precision medical tools, also modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of NdFeB magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in realizing nuts and complex forms in magnets, we recommend using a housing - magnetic holder.
Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these products can complicate diagnosis medical in case of swallowing.
With budget limitations the cost of neodymium magnets is economically unviable,

Lifting parameters

Maximum lifting capacity of the magnet – what it depends on?

Holding force of 2.62 kg is a result of laboratory testing executed under specific, ideal conditions:

using a plate made of low-carbon steel, functioning as a circuit closing element
possessing a massiveness of minimum 10 mm to avoid saturation
with a surface cleaned and smooth
under conditions of ideal adhesion (surface-to-surface)
during detachment in a direction vertical to the plane
at temperature room level

Determinants of lifting force in real conditions

Effective lifting capacity is affected by working environment parameters, including (from priority):

Air gap (between the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or debris).
Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Steel thickness – insufficiently thick plate does not accept the full field, causing part of the power to be wasted into the air.
Chemical composition of the base – mild steel gives the best results. Higher carbon content decrease magnetic properties and holding force.
Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

H&S for magnets

Machining danger

Dust created during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Choking Hazard

NdFeB magnets are not suitable for play. Eating multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates immediate surgery.

Bodily injuries

Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!

Safe operation

Handle magnets consciously. Their powerful strength can shock even experienced users. Plan your moves and do not underestimate their force.

Keep away from electronics

An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets near a smartphone to avoid breaking the sensors.

Warning for allergy sufferers

Some people suffer from a sensitization to Ni, which is the standard coating for NdFeB magnets. Prolonged contact might lead to skin redness. It is best to use protective gloves.

Pacemakers

For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.

Heat warning

Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Magnetic media

Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Fragile material

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