Grip strength weakens significantly with every mm of spacing. Remember that even the smallest gap (e.g., dirt, paint, rust) strongly diminishes the holding power. Magnetic products hold optimally at the point of direct contact; distance weakens the power. Notice how quickly the parameters fall, when the magnet does not touch tightly to the steel surface. When designing the assembly, discard additional spacers.

The following data presents the theoretical holding capacity required to start the sliding of the magnet down on a upright metal surface (assuming standard friction coefficient). The holding force is a function of the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MW 8x1.5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.22 kg / 0.49 pounds 222.0 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 pounds 148.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.07 kg / 0.16 pounds 74.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.37 kg / 0.82 pounds 370.0 g / 3.6 N

When placing a magnet on a upright plane (e.g., a board), it will only hold just approx. 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that magnets slide down faster than they pull off. Designing a wall mount? Consider that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the magnet will slide down under a noticeably lighter load. Using a rubber pad can significantly raise the stability.

12 mm	100%	0.74 kg / 1.63 pounds 740.0 g / 7.3 N

A thin sheet is not enough to conduct the entire magnetic field, which squanders power of the holder. If you mount a strong magnet to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's power, you require a sufficiently solid element of metal. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the holder works worse. We suggest choosing the steel dimension according to the table below.

Table 5: Thermal resistance (material behavior) - thermal limit

40 °C	-2.2%	0.72 kg / 1.60 pounds 723.7 g / 7.1 N	OK

100 °C	-28.8%	0.53 kg / 1.16 pounds 526.9 g / 5.2 N

Classic neodymiums change their properties power after exceeding the maximum temperature. Watch out for overheating – heat can permanently destroy this product. With every degree above norm, the neodymium's capacity briefly decreases. Do not use this magnet in hot environments higher than its working range. Exceeding the critical threshold will lead to destruction of magnetism.

*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization sooner than taller cylinders. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet setup. The connection of magnet-to-magnet creates a more powerful interaction and a wider radius of performance. Designing a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is huge. The repulsion force is a bit weaker than the attraction, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the geometric center between the magnets (due to field cancellation).
Note: Results refer to friction force of two matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a serious hazard to electronic devices as well as pacemakers. These neodymiums generate a field that disrupts operation of digital equipment. Notice: the unseen radiation passes through tissues and housings. Increased vigilance must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (cracking risk) - collision effects

100 mm	114.91 km/h (31.92 m/s)	0.29 J

Magnetic elements are prone to chipping – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Kinetic force can cause material chips or injury to skin. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Use safety goggles when working with large magnets.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Contrary to myths, water does not block the magnetic field. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains merely ~20% of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) drastically limits the holding force.

3. Temperature resistance

*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) = 0.27

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, composed of advanced NdFeB material, which, with dimensions of Ø8x1.5 mm, guarantees maximum efficiency. The MW 8x1.5 / N38 component boasts a tolerance of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.74 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing 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 pull force of 7.27 N with a weight of only 0.57 g, this cylindrical magnet is indispensable in electronics 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 chipping the coating of this precision component. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need the strongest magnets in the same volume (Ø8x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.

This model is characterized by dimensions Ø8x1.5 mm, which, at a weight of 0.57 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 0.74 kg (force ~7.27 N), which, with such compact 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 8 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.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Advantages

Apart from their strong holding force, neodymium magnets have these key benefits:

They retain magnetic properties for almost ten years – the loss is just ~1% (in theory),
They maintain their magnetic properties even under external field action,
A magnet with a metallic nickel surface looks better,
Magnetic induction on the surface of the magnet remains exceptional,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
In view of the ability of precise molding and customization to custom requirements, neodymium magnets can be modeled in a wide range of geometric configurations, which increases their versatility,
Significant place in advanced technology sectors – they are used in mass storage devices, drive modules, advanced medical instruments, as well as modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
Neodymium magnets lose their strength 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 stability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
We suggest casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can disrupt the diagnostic process medical after entering the body.
With large orders the cost of neodymium magnets can be a barrier,

Lifting parameters

Detachment force of the magnet in optimal conditions – what affects it?

The declared magnet strength refers to the peak performance, obtained under optimal environment, namely:

using a plate made of high-permeability steel, acting as a ideal flux conductor
whose thickness equals approx. 10 mm
characterized by smoothness
without the slightest clearance between the magnet and steel
under perpendicular application of breakaway force (90-degree angle)
at temperature room level

Key elements affecting lifting force

Real force is influenced by specific conditions, including (from priority):

Distance – the presence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Safe handling of neodymium magnets

Machining danger

Machining of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Nickel allergy

Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, avoid direct skin contact or choose encased magnets.

Health Danger

Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Electronic hazard

Do not bring magnets near a wallet, computer, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Do not overheat magnets

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

No play value

Always store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are fatal.

Caution required

Use magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their force.

Crushing force

Risk of injury: The pulling power is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.

Compass and GPS

Note: neodymium magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.

Shattering risk

NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them shattering into small pieces.
