Pulling power weakens drastically per each millimeter of spacing. Note that every additional insulation layer (e.g., dirt, varnish, dust) significantly reduces the pull force. Neodymiums work strongest at the point of direct contact; air break drastically cuts the force. Analyze how rapidly the pull force drop, when the magnet does not adhere tightly to the metal substrate. When designing the mounting, discard unnecessary gaps.

The table below indicates the theoretical holding capacity needed to cause the shifting of the magnet down against a upright metal surface (considering typical friction coefficient). This parameter is a function of the distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 20x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.49 kg / 1.08 LBS 489.0 g / 4.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.33 kg / 0.72 LBS 326.0 g / 3.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.16 kg / 0.36 LBS 163.0 g / 1.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.82 kg / 1.80 LBS 815.0 g / 8.0 N

When placing a magnet on a upright wall (e.g., a fridge), it you can count on only about 1/5 of its maximum pull force. Gravity as well as a low friction coefficient influence the fact that holders slide down easier than they pop off the substrate. Designing a hanger? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a noticeably lighter weight. Application of an anti-slip pad can significantly improve the result.

A too thin steel is incapable of absorb the entire magnetic field, which wastes potential of the magnet. Should you install a neodymium to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this magnet's potential, you require a sufficiently solid element of steel. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the product shows lower pull force. We recommend selecting the steel dimension according to the table below.

Classic neodymiums change their properties parameters above the temperature limit. Avoid high temperatures – excessive heat can permanently damage this magnet. With increasing heat, the magnet's capacity momentarily lowers. Do not use this magnet in hot environments exceeding its operating temperature limit. Exceeding the critical threshold will cause permanent loss of magnetism.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (pancake types) risk losing magnetic properties at lower temperatures compared to rod magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and steel combination. Such a system of magnet-to-magnet creates a more powerful interaction and a wider radius of performance. Designing a powerful holder? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when attracting two neodymiums, the impact force is extreme. The repulsion force is slightly lower than the connection force, but still large.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).
* Results demonstrate sliding force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a large risk to IT equipment and pacemakers. These neodymiums generate a field that disrupts operation of digital equipment. Notice: the invisible magnetic field penetrates the body and plastic. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - collision effects

Neodymium magnets are delicate – a violent impact against metal causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Kinetic force can cause material chips or dangerous crushing to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when working with powerful specimens.

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

1. Shear force

*Caution: On a vertical wall, the magnet holds merely approx. 20-30% of its max power.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Power loss vs temp

*For N38 material, 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) = 0.16

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 offered product is a very strong rod magnet, produced from durable NdFeB material, which, at dimensions of Ø20x2 mm, guarantees optimal power. This specific item boasts high dimensional repeatability and professional build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.63 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Additionally, its triple-layer Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is perfect for building electric motors, advanced sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the high power of 16.02 N with a weight of only 4.71 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this precision component. 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.

Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø20x2), 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 20 mm and height 2 mm. The value of 16.02 N means that the magnet is capable of holding a weight many times exceeding its own mass of 4.71 g. The product has a [NiCuNi] coating, which secures it 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 20 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 Nd₂Fe₁₄B magnets.

Strengths

Apart from their consistent magnetic energy, neodymium magnets have these key benefits:

Their strength remains stable, and after around 10 years it decreases only by ~1% (theoretically),
They retain their magnetic properties even under external field action,
A magnet with a shiny silver surface looks better,
Magnets exhibit very high magnetic induction on the outer side,
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...
Thanks to freedom in forming and the capacity to adapt to client solutions,
Universal use in innovative solutions – they are used in computer drives, brushless drives, advanced medical instruments, as well as complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in miniature devices

Weaknesses

Disadvantages of NdFeB magnets:

At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose their power 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 durability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited ability of producing nuts in the magnet and complex shapes - preferred is casing - magnetic holder.
Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Maximum magnetic pulling force – what contributes to it?

The declared magnet strength concerns the limit force, obtained under ideal test conditions, namely:

on a base made of structural steel, effectively closing the magnetic flux
possessing a thickness of minimum 10 mm to avoid saturation
characterized by smoothness
without the slightest insulating layer between the magnet and steel
under axial application of breakaway force (90-degree angle)
in temp. approx. 20°C

What influences lifting capacity in practice

Bear in mind that the application force may be lower depending on the following factors, in order of importance:

Air gap (betwixt the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
Direction of force – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
Steel thickness – too thin sheet does not close the flux, causing part of the power to be wasted into the air.
Material type – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.

H&S for magnets

Magnet fragility

Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them cracking into small pieces.

Allergy Warning

Certain individuals suffer from a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact may cause a rash. We suggest use safety gloves.

ICD Warning

Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Impact on smartphones

A powerful magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent damaging the sensors.

Bodily injuries

Danger of trauma: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.

Danger to the youngest

Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.

Do not drill into magnets

Mechanical processing of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Handling guide

Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Data carriers

Do not bring magnets near a purse, computer, or screen. The magnetic field can destroy these devices and erase data from cards.

Operating temperature

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
