Magnetic force decreases sharply per each millimeter of spacing. Remember that even a very thin break (e.g., contamination, paint, dust) significantly diminishes the holding power. Magnetic products work most effectively in perfect adhesion; distance kills the force. See how quickly the load capacity plummet, when the product does not adhere flatly to the metal substrate. When planning the assembly, avoid unnecessary gaps.

The table below calculates the estimated weight limit needed to cause the sliding of the magnet down along a upright metal surface (assuming typical friction coefficient). The holding force varies with the air gap between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 18x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.29 kg / 0.63 LBS 285.0 g / 2.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.19 kg / 0.42 LBS 190.0 g / 1.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.10 kg / 0.21 LBS 95.0 g / 0.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.48 kg / 1.05 LBS 475.0 g / 4.7 N

When placing a holder on a upright plane (e.g., a car body), it you can count on only approx. 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip mean that products slip faster than they pull off. Planning a wall mount? Note that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the holder will slip down under a significantly smaller weight. Utilizing a rubberized coating can drastically improve the result.

12 mm	100%	0.95 kg / 2.09 LBS 950.0 g / 9.3 N

A thin sheet cannot take in the full magnetic flux, which weakens actual performance of the holder. If you mount a strong magnet to a too thin substrate, the field will penetrate right through and the holding will be smaller. To achieve 100% of this magnet's potential, you require a sufficiently solid element of steel. The material oversaturation causes that on thin elements (e.g., thin profiles), the magnet works worse. We recommend selecting the steel dimension based on the following data.

Ordinary NdFeB products lose parameters after exceeding the maximum temperature. Avoid high temperatures – excessive heat can permanently demagnetize this magnet. With increasing heat, the neodymium's capacity briefly lowers. Do not use this magnet in hot environments exceeding its working range. Exceeding the critical threshold will result in permanent loss of magnetism.

*Technical advisory: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a neodymium and metal combination. Such a system of magnet-to-magnet produces a massive flux and a further horizon of action. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the collision energy is massive. The repulsion force is marginally weaker than the connection force, but still large.
*Flux density between like poles is approximately ~0 Gs in the exact middle of the gap (resulting from vector opposition).
Attention: Estimates apply to friction force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a serious hazard to electronics and medical implants. These NdFeB products generate a field that disrupts operation of digital equipment. Notice: the invisible magnetic field penetrates the body and plastic. Special caution must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

NdFeB products are very brittle – a strong collision with metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can cause material chips or injury to fingers. Be sure to control the product during bringing near metal so it doesn't hit violently against the metal. A collision at high speed means shattering of the neodymium. Wear safety glasses when handling with large magnets.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds just a fraction of its max power.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.13

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 cylinder magnet, manufactured from modern NdFeB material, which, with dimensions of Ø18x1.5 mm, guarantees optimal power. This specific item boasts high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 0.95 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring 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 9.34 N with a weight of only 2.86 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, 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, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Magnets N38 are strong enough for 90% of applications in automation and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø18x1.5), 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 Ø18x1.5 mm, which, at a weight of 2.86 g, makes it an element with impressive magnetic energy density. The value of 9.34 N means that the magnet is capable of holding a weight many times exceeding its own mass of 2.86 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 1.5 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 diametrically if your project requires it.

Strengths as well as weaknesses of rare earth magnets.

Pros

Besides their immense field intensity, neodymium magnets offer the following advantages:

They retain magnetic properties for nearly 10 years – the loss is just ~1% (based on simulations),
Neodymium magnets are characterized by remarkably resistant to loss of magnetic properties caused by external interference,
In other words, due to the smooth finish of gold, the element becomes visually attractive,
Magnets have excellent magnetic induction on the surface,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
Thanks to versatility in constructing and the ability to customize to specific needs,
Universal use in electronics industry – they are utilized in HDD drives, electromotive mechanisms, medical devices, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in compact constructions

Weaknesses

Disadvantages of NdFeB magnets:

At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic holder, due to difficulties in creating threads inside the magnet and complex shapes.
Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, small elements of these devices can complicate diagnosis medical after entering the body.
Due to neodymium price, their price exceeds standard values,

Pull force analysis

Maximum magnetic pulling force – what contributes to it?

The load parameter shown refers to the limit force, measured under optimal environment, namely:

on a plate made of mild steel, optimally conducting the magnetic flux
with a thickness no less than 10 mm
with a surface free of scratches
with direct contact (no coatings)
for force applied at a right angle (in the magnet axis)
at standard ambient temperature

Lifting capacity in practice – influencing factors

Effective lifting capacity impacted by specific conditions, mainly (from priority):

Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 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.
Plate thickness – too thin plate causes magnetic saturation, causing part of the power to be wasted to the other side.
Material type – the best choice is pure iron steel. Stainless steels may attract less.
Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, reducing force.
Temperature – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

Precautions when working with NdFeB magnets

Heat sensitivity

Keep cool. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Keep away from computers

Equipment safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).

Fragile material

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

Medical implants

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

Crushing force

Pinching hazard: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.

Do not give to children

Strictly store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.

Fire risk

Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Warning for allergy sufferers

Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands and opt for coated magnets.

Precision electronics

Note: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, device, and GPS.

Do not underestimate power

Handle with care. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can move away.
