Pulling power decreases sharply with every subsequent millimeter of spacing. Remember that every additional insulation layer (e.g., dirt, paint, veneer) noticeably weakens the grip. Magnetic products hold strongest at the point of direct contact; distance drastically cuts the power. Analyze how quickly the load capacity fall, when the product does not adhere flatly to the steel surface. When designing the mounting, avoid redundant distances.

The table below defines the approximate shear load needed to initiate the sliding of the magnet vertically on a vertical metal surface (assuming typical friction). The holding force is relative to the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 12x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.13 kg / 0.28 LBS 126.0 g / 1.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.08 kg / 0.19 LBS 84.0 g / 0.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.04 kg / 0.09 LBS 42.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.21 kg / 0.46 LBS 210.0 g / 2.1 N

When mounting a holder on a upright surface (e.g., a fridge), it you can count on only about 1/5 of its nominal power. Gravitational force and a low friction coefficient cause that products slip easier than they pull off. Designing a vertical fastening? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a significantly smaller load. Using a rubber layer can significantly improve the result.

12 mm	100%	0.42 kg / 0.93 LBS 420.0 g / 4.1 N

A too thin steel cannot focus the entire magnetic field, which weakens actual performance of the magnet. If you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this magnet's potential, you need a suitably thick backing of steel. The saturation effect causes that on sheet metal structures (e.g., appliance housings), the holder holds weaker. We suggest choosing the steel thickness from these parameters.

Ordinary NdFeB products lose parameters past the thermal threshold. Watch out for overheating – heat can permanently demagnetize this magnet. As the temperature rises, the neodymium's force briefly drops. Avoid using this magnet close to heaters exceeding its safe range. Ignoring the limit will result in destruction of magnetic properties.

*Important note: Temperature resistance is determined by both grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) risk losing magnetic properties sooner compared to rod magnets. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a significantly greater distance than a magnet and steel combination. The setup of two magnets generates a stronger field and a wider radius of performance. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is extreme. The levitation is slightly lower than the attraction, but still impressive.
*Flux density for N-N configuration reaches ~0 Gs at the midpoint between the magnets (due to field cancellation).
Important: Estimates apply to shear force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to electronic devices as well as medical implants. These magnets generate a field that destroys function of sensitive medical devices. Remember: the unseen radiation acts through matter and glass. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Pay attention to connection velocity – a magnet released freely turns into a projectile. Impact energy can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during installation so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the magnet. Use safety goggles when playing with powerful specimens.

Rust risk: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Caution: On a vertical wall, the magnet retains merely approx. 20-30% of its nominal pull.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) severely reduces the holding force.

3. Power loss vs temp

*For N38 material, the critical limit is 80°C.

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

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

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 an exceptionally strong cylindrical magnet, composed of advanced NdFeB material, which, at dimensions of Ø12x1 mm, guarantees maximum efficiency. The MW 12x1 / N38 component boasts a tolerance of ±0.1mm and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.42 kg), this product is available off-the-shelf from our European logistics center, ensuring quick order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building generators, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 4.15 N with a weight of only 0.85 g, this rod is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 12.1 mm) using epoxy glues. To ensure stability 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 popular 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 (Ø12x1), 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 12 mm and height 1 mm. The key parameter here is the lifting capacity amounting to approximately 0.42 kg (force ~4.15 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, 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 12 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 as well as weaknesses of Nd₂Fe₁₄B magnets.

Pros

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

They retain magnetic properties for almost ten years – the loss is just ~1% (based on simulations),
They do not lose their magnetic properties even under external field action,
Thanks to the metallic finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an elegant appearance,
Magnets have impressive magnetic induction on the active area,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
Thanks to versatility in forming and the ability to customize to client solutions,
Key role in innovative solutions – they are utilized in magnetic memories, electric motors, advanced medical instruments, as well as multitasking production systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

What to avoid - cons of neodymium magnets and proposals for their use:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in producing threads and complex shapes in magnets, we recommend using a housing - magnetic mount.
Health risk related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, small elements of these devices are able to disrupt the diagnostic process medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Highest magnetic holding force – what contributes to it?

Breakaway force is the result of a measurement for ideal contact conditions, assuming:

with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
whose transverse dimension is min. 10 mm
characterized by smoothness
with zero gap (no impurities)
during pulling in a direction perpendicular to the plane
at temperature room level

Determinants of lifting force in real conditions

Effective lifting capacity impacted by working environment parameters, including (from priority):

Air gap (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
Plate thickness – insufficiently thick sheet does not close the flux, causing part of the flux to be wasted into the air.
Chemical composition of the base – mild steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

H&S for magnets

Danger to the youngest

Absolutely keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.

Medical implants

Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

GPS Danger

An intense magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Do not bring magnets near a device to prevent damaging the sensors.

Electronic hazard

Equipment safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).

Heat sensitivity

Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).

Nickel allergy

Medical facts indicate that nickel (the usual finish) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for coated magnets.

Magnet fragility

Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Fire warning

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.

Caution required

Exercise caution. Rare earth magnets act from a distance and connect with huge force, often quicker than you can react.

Bodily injuries

Big blocks can smash fingers instantly. Do not place your hand betwixt two attracting surfaces.
