Magnetic force decreases drastically with every subsequent millimeter of spacing. Remember that even a very thin break (e.g., contamination, paint, dust) significantly diminishes the holding power. Magnets operate strongest in perfect adhesion; distance kills the force. See how flashily the pull force plummet, when the product does not adhere flatly to the metal substrate. When designing the assembly, eliminate unnecessary gaps.

The table below presents the estimated force needed to initiate the downward movement of the magnet vertically along a upright steel plate (considering typical friction coefficient). The holding force varies with the distance between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.25 kg / 0.56 lbs 252.0 g / 2.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.17 kg / 0.37 lbs 168.0 g / 1.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.19 lbs 84.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.42 kg / 0.93 lbs 420.0 g / 4.1 N

When hanging a magnet on a vertical plane (e.g., a fridge), it will maintain just approx. 20%-30% of its maximum pull force. Gravity and a weak degree of grip cause that products move down faster than they pop off the substrate. Planning a vertical fastening? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a noticeably lighter cargo. Utilizing a rubberized pad can effectively increase the grip.

A thin metal plate is incapable of focus the entire magnetic field, which weakens actual performance of the magnet. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To achieve the maximum of this magnet's potential, you require a sufficiently solid element of metal. The saturation effect means that on delicate walls (e.g., thin profiles), the holder holds weaker. We advise picking the steel thickness according to the table below.

Ordinary NdFeB products irreversibly lose parameters above the temperature limit. Avoid high temperatures – excessive heat can irreversibly damage this magnet. With every degree above norm, the neodymium's power temporarily decreases. Avoid using this magnet near heat sources higher than its working range. Too high temperature will lead to permanent loss of magnetic properties.

*Important note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) may lose charge permanently sooner than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets creates a more powerful interaction and a wider radius of performance. Designing a strong closure? Apply two magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the pinch force is huge. The levitation is a bit weaker than the attraction, but still significant.
*The magnetic induction between like poles drops to ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Results refer to friction force of two matching magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a large risk to electronic devices and medical implants. These magnets produce a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field acts through matter and housings. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

NdFeB products are delicate – a violent impact against metal causes immediate chipping. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or painful pinches to skin. Be sure to control the product during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear safety glasses when handling with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Vertical hold

*Caution: On a vertical surface, the magnet retains only a fraction of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) drastically weakens the holding force.

3. Heat tolerance

*For standard magnets, 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) = 0.79

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 presented product is an incredibly powerful cylinder magnet, manufactured from modern NdFeB material, which, with dimensions of Ø5x4 mm, guarantees the highest energy density. This specific item is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.84 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 8.24 N with a weight of only 0.59 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. To ensure long-term durability 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 (Ø5x4), 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 5 mm and height 4 mm. The value of 8.24 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.59 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 4 mm), which means that the N and S poles are located on the flat, circular surfaces. 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.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
They do not lose their magnetic properties even under strong external field,
Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an clean appearance,
The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
Thanks to flexibility in forming and the capacity to adapt to client solutions,
Versatile presence in advanced technology sectors – they serve a role in mass storage devices, electric drive systems, medical equipment, also modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Limitations

Disadvantages of NdFeB magnets:

At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
We warn that neodymium magnets can reduce their strength 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 advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
Limited ability of producing threads in the magnet and complicated shapes - recommended is cover - magnetic holder.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products can be problematic in diagnostics medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Magnetic strength at its maximum – what contributes to it?

Holding force of 0.84 kg is a theoretical maximum value executed under specific, ideal conditions:

with the contact of a yoke made of special test steel, ensuring full magnetic saturation
with a thickness minimum 10 mm
with an ideally smooth contact surface
under conditions of ideal adhesion (metal-to-metal)
under perpendicular force direction (90-degree angle)
at conditions approx. 20°C

Practical aspects of lifting capacity – factors

Bear in mind that the magnet holding may be lower influenced by the following factors, starting with the most relevant:

Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be escaped into the air.
Material composition – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the holding force is lower. In addition, even a small distance between the magnet and the plate lowers the holding force.

Warnings

Swallowing risk

These products are not intended for children. Swallowing several magnets may result in them pinching intestinal walls, which poses a critical condition and necessitates urgent medical intervention.

Protect data

Intense magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.

Threat to navigation

An intense magnetic field interferes with the operation of compasses in phones and navigation systems. Maintain magnets close to a smartphone to prevent damaging the sensors.

Do not overheat magnets

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

ICD Warning

Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Mechanical processing

Powder produced during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Protective goggles

Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Do not underestimate power

Be careful. Neodymium magnets act from a long distance and snap with huge force, often faster than you can react.

Bodily injuries

Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand between two strong magnets.

Allergic reactions

Some people experience a sensitization to Ni, which is the standard coating for neodymium magnets. Frequent touching may cause skin redness. It is best to wear protective gloves.
