Pulling power drops significantly with every subsequent millimeter of distance. Remember that even the smallest gap (e.g., contamination, varnish, rust) noticeably weakens the grip. Neodymiums work most effectively during direct contact; distance nullifies the power. See how quickly the parameters plummet, when the magnet does not touch directly to the metal substrate. When calculating the mounting, eliminate unnecessary gaps.

The following data shows the approximate force required to cause the shifting of the magnet down on a vertical steel plate (assuming standard friction coefficient). This value depends on the air gap between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 10x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.58 kg / 1.27 lbs 576.0 g / 5.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.38 kg / 0.85 lbs 384.0 g / 3.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.42 lbs 192.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.96 kg / 2.12 lbs 960.0 g / 9.4 N

When placing a magnet on a vertical plane (e.g., a board), it will maintain barely approx. 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip mean that magnets slide down easier than they pull off. Planning a hanger? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a significantly smaller load. Using a rubber pad can drastically raise the stability.

12 mm	100%	1.92 kg / 4.23 lbs 1920.0 g / 18.8 N

A too thin steel is incapable of take in the entire magnetic field, which weakens actual performance of the magnet. If you mount a strong magnet to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this neodymium's potential, you need a suitably thick piece of steel. The saturation effect causes that on thin elements (e.g., thin profiles), the holder holds weaker. We suggest choosing the steel dimension from these parameters.

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Watch out for overheating – heat can irreversibly destroy this magnet. With increasing heat, the neodymium's capacity momentarily decreases. Refrain from using this product near heat sources higher than its operating temperature limit. Too high temperature will result in destruction of magnetic properties.

*Engineering note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) are more susceptible to demagnetization at lower temperatures than taller cylinders. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two strong neodymiums interact from a wider radius than a magnet and steel setup. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is huge. The repulsion force is a bit weaker than the connection force, but still large.
*The magnetic induction for N-N configuration drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
* Calculations refer to sliding force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a serious hazard to electronic devices and medical implants. These NdFeB products produce a field that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation passes through tissues and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or injury to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the neodymium. Use safety goggles when working with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

The magnetic field penetrates through water without any losses. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

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

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) = 1.38

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 cylinder magnet, composed of modern NdFeB material, which, with dimensions of Ø10x30 mm, guarantees the highest energy density. This specific item is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 1.92 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating secures 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 pull force of 18.79 N with a weight of only 17.67 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

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., 10.1 mm) using two-component epoxy glues. 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 frequently chosen standard for professional neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø10x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 10 mm and height 30 mm. The value of 18.79 N means that the magnet is capable of holding a weight many times exceeding its own mass of 17.67 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 10 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.

Strengths and weaknesses of rare earth magnets.

Benefits

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

Their power is durable, and after around ten years it drops only by ~1% (according to research),
They maintain their magnetic properties even under close interference source,
By applying a smooth layer of silver, the element presents an aesthetic look,
Neodymium magnets deliver maximum magnetic induction on a contact point, which allows for strong attraction,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
Possibility of precise creating as well as optimizing to concrete applications,
Fundamental importance in modern technologies – they find application in mass storage devices, electric motors, medical equipment, as well as multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
Due to limitations in creating threads and complicated shapes in magnets, we propose using a housing - magnetic holder.
Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these products 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 increases costs of application in large quantities

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what contributes to it?

The load parameter shown represents the peak performance, obtained under optimal environment, meaning:

on a base made of mild steel, optimally conducting the magnetic flux
with a cross-section of at least 10 mm
characterized by lack of roughness
with total lack of distance (no impurities)
during detachment in a direction vertical to the mounting surface
in stable room temperature

Impact of factors on magnetic holding capacity in practice

Bear in mind that the magnet holding may be lower subject to elements below, in order of importance:

Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Steel grade – ideal substrate is pure iron steel. Hardened steels may attract less.
Surface finish – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

H&S for magnets

Product not for children

Neodymium magnets are not intended for children. Eating several magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.

Conscious usage

Exercise caution. Rare earth magnets act from a distance and snap with massive power, often quicker than you can react.

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.

GPS and phone interference

An intense magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a device to prevent breaking the sensors.

Electronic devices

Intense magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.

Permanent damage

Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.

Shattering risk

Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.

Crushing risk

Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Do not drill into magnets

Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Life threat

Individuals with a ICD have to keep an large gap from magnets. The magnetism can disrupt the functioning of the implant.
