Grip strength drops significantly with every subsequent millimeter of spacing. Note that even the smallest gap (e.g., dirt, paint, veneer) significantly diminishes the holding power. Neodymiums hold most effectively during direct contact; air break weakens the power. Notice how rapidly the load capacity drop, when the magnet does not adhere flatly to the steel surface. When designing the arrangement, eliminate additional spacers.

This section presents the theoretical shear load required to initiate the downward movement of the magnet downwards against a vertical steel plate (considering standard friction). This value is a function of the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MW 9.5x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.12 kg / 0.26 lbs 120.0 g / 1.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.08 kg / 0.18 lbs 80.0 g / 0.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.09 lbs 40.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.20 kg / 0.44 lbs 200.0 g / 2.0 N

When mounting a element on a upright surface (e.g., a board), it will maintain only about 1/5 of its nominal power. Gravity and a low friction coefficient influence the fact that magnets slide down faster than they pop off the substrate. Designing a vertical fastening? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a much lighter cargo. Application of an anti-slip coating can effectively increase the grip.

12 mm	100%	0.40 kg / 0.88 lbs 400.0 g / 3.9 N

A thin sheet is not enough to focus the entire magnetic field, which squanders power of the holder. Should you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this magnet's power, you need a suitably thick backing of steel. The material oversaturation means that on thin elements (e.g., car bodies), the magnet holds weaker. We recommend selecting the steel thickness according to the table below.

Table 5: Working in heat (stability) - resistance threshold
MW 9.5x1 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	0.40 kg / 0.88 lbs 400.0 g / 3.9 N	OK
40 °C	-2.2%	0.39 kg / 0.86 lbs 391.2 g / 3.8 N	OK
60 °C	-4.4%	0.38 kg / 0.84 lbs 382.4 g / 3.8 N
80 °C	-6.6%	0.37 kg / 0.82 lbs 373.6 g / 3.7 N
100 °C	-28.8%	0.28 kg / 0.63 lbs 284.8 g / 2.8 N

Standard neodymium magnets lose parameters past the thermal threshold. Protect against heat – high temperature can permanently demagnetize this product. With increasing heat, the magnet's power briefly decreases. Avoid using this magnet in hot environments exceeding its working range. Too high temperature will cause irreversible degradation of magnetism.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently sooner than long magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums 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. Planning to create a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when connecting a pair of magnets, the collision energy is extreme. The repulsion force is marginally weaker than the attraction, but still significant.
*Flux density between like poles reaches ~0 Gs at the midpoint of the gap (due to field cancellation).
* Results show sliding force of dual same magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - precautionary measures
MW 9.5x1 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	3.0 cm
Hearing aid	10 Gs (1.0 mT)	2.5 cm
Timepiece	20 Gs (2.0 mT)	2.0 cm

Payment card	400 Gs (40.0 mT)	0.5 cm
HDD hard drive	600 Gs (60.0 mT)	0.5 cm

A strong magnetic field poses a large risk to electronics and pacemakers. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Be aware: 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: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - collision effects
MW 9.5x1 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	27.80 km/h (7.72 m/s)	0.02 J
30 mm	47.99 km/h (13.33 m/s)	0.05 J
50 mm	61.95 km/h (17.21 m/s)	0.08 J
100 mm	87.61 km/h (24.34 m/s)	0.16 J

Neodymium magnets are prone to chipping – a strong collision with metal can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or painful pinches to skin. Always hold the magnet during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Use safety goggles when playing with powerful specimens.

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. Wall mount (shear)

*Caution: On a vertical wall, the magnet retains only ~20% of its max power.

2. Plate thickness effect

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

3. Heat tolerance

*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) = 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, manufactured from advanced NdFeB material, which, with dimensions of Ø9.5x1 mm, guarantees maximum efficiency. This specific item is characterized by a tolerance of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 0.40 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 3.96 N with a weight of only 0.53 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a tolerance of ±0.1mm, the best method is to glue them into holes with a slightly larger diameter (e.g., 9.5.1 mm) using two-component epoxy glues. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets N38 are suitable for the majority of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø9.5x1), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 9.5 mm and height 1 mm. The key parameter here is the holding force amounting to approximately 0.40 kg (force ~3.96 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.

This rod magnet is magnetized axially (along the height of 1 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.

Pros and cons of rare earth magnets.

Benefits

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

They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
They possess excellent resistance to weakening of magnetic properties due to external magnetic sources,
In other words, due to the metallic layer of nickel, the element becomes visually attractive,
Magnets are distinguished by extremely high magnetic induction on the working surface,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Thanks to modularity in shaping and the capacity to adapt to specific needs,
Universal use in high-tech industry – they are utilized in HDD drives, motor assemblies, medical equipment, as well as complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems

Weaknesses

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing threads and complicated forms in magnets, we propose using cover - magnetic holder.
Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small components of these products are able to be problematic in diagnostics medical in case of swallowing.
With budget limitations the cost of neodymium magnets is economically unviable,

Holding force characteristics

Best holding force of the magnet in ideal parameters – what contributes to it?

Breakaway force was determined for ideal contact conditions, taking into account:

with the application of a yoke made of special test steel, ensuring full magnetic saturation
possessing a massiveness of min. 10 mm to avoid saturation
with an ground contact surface
without any insulating layer between the magnet and steel
for force acting at a right angle (in the magnet axis)
at temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

Holding efficiency impacted by working environment parameters, mainly (from most important):

Distance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate reduces the holding force.

Warnings

Crushing risk

Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.

Fire warning

Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Magnetic media

Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.

GPS and phone interference

Note: neodymium magnets generate a field that confuses sensitive sensors. Keep a separation from your phone, device, and GPS.

Product not for children

NdFeB magnets are not toys. Eating multiple magnets may result in them attracting across intestines, which constitutes a severe health hazard and requires immediate surgery.

Protective goggles

NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them breaking into small pieces.

Medical implants

Individuals with a heart stimulator must maintain an safe separation from magnets. The magnetism can interfere with the functioning of the implant.

Respect the power

Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.

Permanent damage

Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.

Skin irritation risks

It is widely known that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, refrain from touching magnets with bare hands or select encased magnets.
