Pulling power decreases significantly with every mm of spacing. Note that even a very thin break (e.g., contamination, varnish, rust) noticeably diminishes the holding power. Magnets work most effectively during direct contact; gap weakens the power. See how quickly the parameters drop, when the product does not adhere flatly to the metal substrate. When planning the assembly, eliminate additional spacers.

This section indicates the approximate holding capacity required to initiate the downward movement of the magnet down against a vertical steel plate (considering typical friction coefficient). The holding force is relative to the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.85 lbs 384.0 g / 3.8 N

When placing a holder on a upright wall (e.g., a fridge), it you can count on barely approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip influence the fact that holders slide down faster than they pop off the substrate. Designing a wall mount? Note that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slip down under a significantly smaller load. Using a rubber coating can effectively increase the grip.

12 mm	100%	1.92 kg / 4.23 lbs 1920.0 g / 18.8 N

A thin sheet cannot conduct the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the holding will be smaller. To squeeze full efficiency of this neodymium's power, you require a sufficiently solid backing of metal. The saturation effect causes that on delicate walls (e.g., car bodies), the holder holds weaker. We advise picking the steel cross-section according to the table below.

Standard neodymium magnets irreversibly lose power after exceeding the maximum temperature. Protect against heat – excessive heat can irreversibly demagnetize this product. With increasing heat, the neodymium's force temporarily decreases. Do not use this magnet near heat sources exceeding its operating temperature limit. Ignoring the limit will cause irreversible degradation of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) risk losing magnetic properties sooner compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a wider radius than a magnet and steel combination. The setup of magnet-to-magnet produces a massive flux and a wider radius of performance. Designing a strong closure? Use a pair of magnets instead of one magnet and a steel. Remember that when connecting a pair of magnets, the impact force is huge. The levitation is marginally weaker than the connection force, but still impressive.
*The magnetic induction for N-N configuration drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Figures show friction force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to electronic devices as well as medical implants. These neodymiums generate a flux that disrupts operation of digital equipment. Notice: the invisible magnetic field penetrates the body and glass. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (cracking risk) - warning

100 mm	33.24 km/h (9.23 m/s)	0.75 J

Neodymium magnets are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can cause material chips or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when handling with large magnets.

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 wall, the magnet holds merely ~20% of its max power.

2. Steel thickness impact

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

3. Power loss vs temp

*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) = 1.38

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 rod magnet, produced from modern NdFeB material, which, at dimensions of Ø10x30 mm, guarantees the highest energy density. This specific item is characterized by high dimensional repeatability and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 1.92 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, guaranteeing 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 high power of 18.79 N with a weight of only 17.67 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this professional component. To ensure long-term durability in industry, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade 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 (Ø10x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø10x30 mm, which, at a weight of 17.67 g, makes it an element with high magnetic energy density. The value of 18.79 N means that the magnet is capable of holding a weight many times exceeding its own mass of 17.67 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 30 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 and cons of rare earth magnets.

Benefits

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

They retain magnetic properties for around 10 years – the loss is just ~1% (based on simulations),
They are resistant to demagnetization induced by presence of other magnetic fields,
Thanks to the shimmering finish, the layer of nickel, gold, or silver-plated gives an clean appearance,
The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of exact modeling and adjusting to precise requirements,
Huge importance in modern industrial fields – they are utilized in HDD drives, drive modules, precision medical tools, also technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in miniature devices

Cons

Disadvantages of NdFeB magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer 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 corrode. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited ability of creating threads in the magnet and complicated shapes - recommended is casing - magnet mounting.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to complicate diagnosis medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Lifting parameters

Best holding force of the magnet in ideal parameters – what contributes to it?

The lifting capacity listed is a measurement result performed under standard conditions:

with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
with a thickness minimum 10 mm
with an ideally smooth contact surface
under conditions of no distance (metal-to-metal)
under axial force vector (90-degree angle)
in temp. approx. 20°C

What influences lifting capacity in practice

In real-world applications, the real power results from several key aspects, presented from crucial:

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be wasted to the other side.
Steel grade – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
Temperature – 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 smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Safe handling of neodymium magnets

Compass and GPS

Navigation devices and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.

Danger to the youngest

NdFeB magnets are not suitable for play. Eating multiple magnets can lead to them attracting across intestines, which poses a critical condition and requires immediate surgery.

Keep away from computers

Intense magnetic fields can destroy records on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

Warning for heart patients

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

Fire risk

Dust generated during machining of magnets is combustible. Do not drill into magnets unless you are an expert.

Protective goggles

Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

Warning for allergy sufferers

Some people have a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Frequent touching might lead to an allergic reaction. We recommend wear safety gloves.

Finger safety

Large magnets can smash fingers instantly. Do not put your hand betwixt two attracting surfaces.

Heat sensitivity

Watch the temperature. Heating the magnet to high heat will destroy its magnetic structure and pulling force.

Conscious usage

Handle with care. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.
