Pulling power weakens drastically per each millimeter of spacing. Remember that even a microscopic distance (e.g., contamination, paint, rust) strongly reduces the pull force. Magnetic products work strongest during direct contact; distance kills the power. Notice how rapidly the parameters plummet, when the magnet does not adhere directly to the metal substrate. When designing the mounting, discard redundant distances.

The table below presents the estimated holding capacity required to start the sliding of the magnet down against a upright metal surface (considering typical friction coefficient). This value depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 30x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.61 kg / 5.76 lbs 2613.0 g / 25.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.74 kg / 3.84 lbs 1742.0 g / 17.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.87 kg / 1.92 lbs 871.0 g / 8.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.36 kg / 9.60 lbs 4355.0 g / 42.7 N

When mounting a element on a upright surface (e.g., a fridge), it you can count on only about 20%-30% of its maximum pull force. Gravitational force and a weak degree of grip influence the fact that magnets slide down faster than they pull off. Want to create a vertical fastening? Note that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the element will give way down under a noticeably lighter weight. Utilizing a rubberized layer can drastically raise the stability.

Table 4: Material efficiency (saturation) - sheet metal selection
MW 30x5 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.87 kg / 1.92 lbs 871.0 g / 8.5 N
1 mm	25%	2.18 kg / 4.80 lbs 2177.5 g / 21.4 N
2 mm	50%	4.36 kg / 9.60 lbs 4355.0 g / 42.7 N
3 mm	75%	6.53 kg / 14.40 lbs 6532.5 g / 64.1 N
5 mm	100%	8.71 kg / 19.20 lbs 8710.0 g / 85.4 N
10 mm	100%	8.71 kg / 19.20 lbs 8710.0 g / 85.4 N
11 mm	100%	8.71 kg / 19.20 lbs 8710.0 g / 85.4 N
12 mm	100%	8.71 kg / 19.20 lbs 8710.0 g / 85.4 N

A thin metal plate is not enough to absorb the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a weak sheet, the flux will pass right through and the holding will be smaller. To squeeze full efficiency of this magnet's potential, you need a suitably thick element of steel. The saturation phenomenon means that on thin elements (e.g., car bodies), the product shows lower pull force. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products lose power after exceeding the maximum temperature. Avoid high temperatures – heat can permanently destroy this product. As the temperature rises, the magnet's power momentarily decreases. Avoid using this magnet close to heaters exceeding its working range. Too high temperature will cause irreversible degradation of magnetism.

*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures than long magnets. The danger warning in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a wider radius than a magnet and steel combination. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Remember that when bringing together two magnets, the collision energy is massive. The repulsion force is marginally weaker than the connection force, but still significant.
*Field value between like poles is approximately ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Note: Results apply to shear force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a large risk to electronics as well as medical implants. These magnets generate a field that prevents correct functioning of digital equipment. Remember: the invisible magnetic field acts through matter and housings. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose turns into a projectile. Striking energy can trigger coating fragments or dangerous crushing to skin. Always hold the magnet during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when playing with large magnets.

Rust risk: 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. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

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

2. Efficiency vs thickness

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

3. Thermal stability

*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) = 0.25

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 cylindrical magnet, manufactured from durable NdFeB material, which, at dimensions of Ø30x5 mm, guarantees the highest energy density. This specific item features a tolerance of ±0.1mm and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 8.71 kg), this product is in stock from our European logistics center, ensuring quick 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.

This model is ideal for building generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 85.44 N with a weight of only 26.51 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

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., 30.1 mm) using two-component epoxy glues. To ensure stability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø30x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 30 mm and height 5 mm. The key parameter here is the holding force amounting to approximately 8.71 kg (force ~85.44 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against oxidation, 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 30 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 diametrically if your project requires it.

Pros and cons of rare earth magnets.

Strengths

Besides their remarkable pulling force, neodymium magnets offer the following advantages:

They retain attractive force for almost 10 years – the loss is just ~1% (based on simulations),
They possess excellent resistance to magnetic field loss when exposed to external fields,
By covering with a reflective layer of nickel, the element gains an proper look,
Magnetic induction on the working layer of the magnet turns out to be impressive,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Possibility of accurate machining and adjusting to specific requirements,
Versatile presence in high-tech industry – they serve a role in magnetic memories, electric motors, medical devices, and technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Cons of neodymium magnets and proposals for their use:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and 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 during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We suggest a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
Due to expensive raw materials, their price is higher than average,

Holding force characteristics

Maximum holding power of the magnet – what it depends on?

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

using a plate made of mild steel, acting as a magnetic yoke
with a cross-section of at least 10 mm
with an polished contact surface
with total lack of distance (no coatings)
for force acting at a right angle (in the magnet axis)
at room temperature

Determinants of lifting force in real conditions

Please note that the application force may be lower influenced by elements below, in order of importance:

Distance – existence of any layer (paint, dirt, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
Load vector – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the holding force.

Safety rules for work with NdFeB magnets

Cards and drives

Avoid bringing magnets near a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.

Beware of splinters

Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them shattering into small pieces.

Maximum temperature

Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.

This is not a toy

Absolutely keep magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are fatal.

Warning for allergy sufferers

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact and select versions in plastic housing.

Bodily injuries

Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Do not underestimate power

Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Dust is flammable

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

Keep away from electronics

Be aware: rare earth magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and GPS.

Medical implants

Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
