Magnetic force weakens drastically with every mm of spacing. Keep in mind that even the smallest gap (e.g., contamination, paint, rust) significantly reduces the pull force. Magnetic products operate strongest during direct contact; air break kills the power. See how quickly the load capacity plummet, when the magnet does not adhere directly to the steel surface. When designing the mounting, discard redundant distances.

The following data defines the estimated force sufficient to cause the shifting of the magnet down on a upright steel plate (considering typical friction). The holding force is relative to the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MW 9x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.58 kg / 1.28 LBS 582.0 g / 5.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.39 kg / 0.86 LBS 388.0 g / 3.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.43 LBS 194.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.97 kg / 2.14 LBS 970.0 g / 9.5 N

When placing a holder on a vertical wall (e.g., a fridge), it will maintain barely approx. 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient influence the fact that products slide down faster than they pull off. Planning a vertical fastening? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the element will slip down under a much lighter load. Using a rubber coating can drastically improve the result.

A thin sheet is incapable of take in the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this neodymium's power, you require a sufficiently solid piece of metal. The saturation effect means that on thin elements (e.g., thin profiles), the product works worse. We suggest choosing the steel dimension according to the table below.

Classic neodymiums change their properties power above the temperature limit. Protect against heat – high temperature can irreversibly destroy this magnet. With every degree above norm, the neodymium's capacity temporarily drops. Avoid using this product near heat sources exceeding its safe range. Exceeding the critical threshold will cause destruction of magnetic properties.

*Important note: Temperature resistance is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) are more susceptible to demagnetization at lower temperatures than taller cylinders. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a much further distance than a magnet and sheet combination. The setup of two magnets generates a stronger field and a wider radius of action. Want to build a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the pinch force is huge. The levitation is a bit weaker than the attraction, but still large.
*Flux density in repulsion mode reaches ~0 Gs in the exact middle between the magnets (due to field cancellation).
* Results apply to friction force of a pair of identical magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to IT equipment as well as medical implants. These NdFeB products produce a field that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field passes through tissues and glass. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are delicate – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can destroy the magnet or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the neodymium. Wear eye protection when handling with large magnets.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Sliding resistance

*Caution: On a vertical wall, the magnet holds only ~20% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. computer case) severely weakens the holding force.

3. Temperature resistance

*For N38 grade, 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) = 0.44

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 a very strong rod magnet, composed of advanced NdFeB material, which, with dimensions of Ø9x3 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 1.94 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 18.99 N with a weight of only 1.43 g, this rod is indispensable in electronics and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel 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 (Ø9x3), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø9x3 mm, which, at a weight of 1.43 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 1.94 kg (force ~18.99 N), which, with such defined dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 3 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is standard 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 neodymium magnets.

Benefits

In addition to their pulling strength, neodymium magnets provide the following advantages:

They do not lose strength, even during nearly ten years – the decrease in power is only ~1% (theoretically),
Neodymium magnets are characterized by highly resistant to magnetic field loss caused by magnetic disturbances,
A magnet with a smooth silver surface has an effective appearance,
Magnets possess impressive magnetic induction on the outer layer,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of custom modeling and adapting to atypical needs,
Versatile presence in high-tech industry – they are utilized in magnetic memories, brushless drives, diagnostic systems, also multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Weaknesses

What to avoid - cons of neodymium magnets: application proposals

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures 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 resistant to moisture, when using outdoors
Limited possibility of creating threads in the magnet and complex forms - preferred is cover - magnetic holder.
Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Holding force characteristics

Detachment force of the magnet in optimal conditions – what contributes to it?

Breakaway force was determined for ideal contact conditions, assuming:

using a sheet made of mild steel, acting as a ideal flux conductor
with a thickness minimum 10 mm
with an polished touching surface
under conditions of ideal adhesion (surface-to-surface)
under perpendicular force direction (90-degree angle)
in neutral thermal conditions

Determinants of lifting force in real conditions

Real force impacted by working environment parameters, such as (from most important):

Clearance – existence of any layer (rust, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
Steel thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
Surface quality – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

Precautions when working with NdFeB magnets

Danger to the youngest

Neodymium magnets are not toys. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which poses a direct threat to life and necessitates urgent medical intervention.

Pacemakers

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

Impact on smartphones

An intense magnetic field disrupts the functioning of compasses in phones and navigation systems. Do not bring magnets close to a smartphone to prevent damaging the sensors.

Finger safety

Danger of trauma: The pulling power is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.

Electronic devices

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

Demagnetization risk

Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.

Do not underestimate power

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Shattering risk

Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets leads to them breaking into shards.

Nickel coating and allergies

Studies show that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact or opt for coated magnets.

Flammability

Dust generated during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
