50 mm	5 Gs 0.5 mT	0.00 kg / 0.00 LBS 0.0 g / 0.0 N	weak grip

Magnetic force decreases drastically with every subsequent millimeter of gap. Keep in mind that even a microscopic distance (e.g., contamination, paint, rust) noticeably weakens the grip. Magnets hold optimally during direct contact; distance kills the force. Notice how flashily the pull force drop, when the magnet does not touch tightly to the steel surface. When planning the mounting, discard additional spacers.

The following data presents the theoretical shear load necessary to cause the downward movement of the magnet vertically against a upright steel plate (considering typical friction coefficient). This value depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 5x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.14 kg / 0.30 LBS 135.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 LBS 90.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 LBS 45.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.50 LBS 225.0 g / 2.2 N

When placing a element on a vertical wall (e.g., a fridge), it you can count on just about 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient mean that holders slip faster than they pull off. Planning a vertical fastening? Note that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will slip down under a significantly smaller load. Utilizing a rubberized pad can significantly raise the stability.

Table 4: Steel thickness (substrate influence) - power losses
MW 5x30 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.05 kg / 0.10 LBS 45.0 g / 0.4 N
1 mm	25%	0.11 kg / 0.25 LBS 112.5 g / 1.1 N
2 mm	50%	0.23 kg / 0.50 LBS 225.0 g / 2.2 N
3 mm	75%	0.34 kg / 0.74 LBS 337.5 g / 3.3 N
5 mm	100%	0.45 kg / 0.99 LBS 450.0 g / 4.4 N
10 mm	100%	0.45 kg / 0.99 LBS 450.0 g / 4.4 N
11 mm	100%	0.45 kg / 0.99 LBS 450.0 g / 4.4 N
12 mm	100%	0.45 kg / 0.99 LBS 450.0 g / 4.4 N

A thin metal plate is incapable of take in the entire magnetic field, which wastes potential of the holder. Should you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's power, you require a sufficiently solid element of steel. The material oversaturation means that on delicate walls (e.g., thin profiles), the holder shows lower pull force. We suggest choosing the steel dimension from these parameters.

Classic neodymiums change their properties power after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly demagnetize this product. With increasing heat, the magnet's force temporarily decreases. Avoid using this product in hot environments exceeding its safe range. Too high temperature will cause irreversible degradation of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization sooner compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a wider radius than a magnet and sheet setup. The connection of magnet-to-magnet produces a massive flux and a further horizon of operation. Want to build a strong closure? Apply two magnets instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is massive. The levitation is slightly lower than the connection force, but still significant.
*Field value between like poles reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Note: Results apply to sliding force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to electronic devices as well as medical implants. These NdFeB products generate a flux that disrupts operation of sensitive medical devices. Remember: the unseen radiation penetrates the body and plastic. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a collision with steel causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Impact energy can trigger coating fragments or injury to fingers. 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 ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet retains just a fraction of its nominal pull.

2. Efficiency vs thickness

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

3. Thermal stability

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.59

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 exceptionally strong rod magnet, composed of durable NdFeB material, which, at dimensions of Ø5x30 mm, guarantees optimal power. This specific item boasts an accuracy of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 0.45 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 4.40 N with a weight of only 4.42 g, this rod is indispensable in miniature devices 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 precision component. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø5x30), 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 Ø5x30 mm, which, at a weight of 4.42 g, makes it an element with impressive magnetic energy density. The value of 4.40 N means that the magnet is capable of holding a weight many times exceeding its own mass of 4.42 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 5 mm. 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 Nd₂Fe₁₄B magnets.

Benefits

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

They retain magnetic properties for nearly 10 years – the loss is just ~1% (according to analyses),
Magnets very well defend themselves against demagnetization caused by ambient magnetic noise,
By applying a reflective coating of nickel, the element acquires an professional look,
Magnetic induction on the surface of the magnet is exceptional,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
Due to the possibility of free shaping and adaptation to unique requirements, NdFeB magnets can be produced in a variety of shapes and sizes, which makes them more universal,
Huge importance in future technologies – they are used in hard drives, drive modules, medical devices, as well as other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Problematic aspects of neodymium magnets: application proposals

At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Limited possibility of producing threads in the magnet and complex shapes - preferred is cover - mounting mechanism.
Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum lifting force for a neodymium magnet – what it depends on?

The declared magnet strength represents the maximum value, obtained under ideal test conditions, meaning:

on a block made of structural steel, optimally conducting the magnetic field
possessing a massiveness of minimum 10 mm to avoid saturation
characterized by smoothness
without any air gap between the magnet and steel
under perpendicular force direction (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

Holding efficiency impacted by specific conditions, mainly (from priority):

Distance – the presence of any layer (rust, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Material composition – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

Precautions when working with NdFeB magnets

Do not give to children

Only for adults. Small elements can be swallowed, causing serious injuries. Keep away from kids and pets.

Crushing risk

Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, crushing everything in their path. Be careful!

Eye protection

Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.

Demagnetization risk

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

Compass and GPS

Navigation devices and mobile phones are highly susceptible to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.

Do not underestimate power

Exercise caution. Rare earth magnets act from a long distance and snap with huge force, often faster than you can move away.

Medical interference

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.

Protect data

Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.

Skin irritation risks

Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop working with magnets and wear gloves.

Fire warning

Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
