Engineering analysis of the product - data

The following data constitute the direct effect of a physical calculation. Values were calculated on models for the material Nd₂Fe₁₄B. Actual performance might slightly differ. Treat these data as a reference point for designers.

MW 30x5 / N38

Distance (mm)	Induction (Gauss) / mT	Pull Force (kg/lbs/g/N)	Risk Status

50 mm	43 Gs 4.3 mT	0.00 kg / 0.01 pounds 4.2 g / 0.0 N	weak grip

Grip strength drops sharply with every subsequent millimeter of gap. Note that even a very thin break (e.g., dirt, paint, rust) noticeably reduces the pull force. Magnetic products operate most effectively during direct contact; gap drastically cuts the force. Observe how quickly the load capacity fall, when the magnet does not touch directly to the metal substrate. When calculating the assembly, eliminate additional spacers.

This section defines the estimated weight limit required to cause the slippage of the magnet downwards along a vertical steel wall (considering standard friction). This parameter depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MW 30x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.61 kg / 5.76 pounds 2613.0 g / 25.6 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.74 kg / 3.84 pounds 1742.0 g / 17.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.87 kg / 1.92 pounds 871.0 g / 8.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.36 kg / 9.60 pounds 4355.0 g / 42.7 N

When placing a holder on a upright wall (e.g., a board), it will only hold barely approx. 20%-30% of nominal attraction strength. Gravitational force and a weak degree of grip influence the fact that magnets move down faster than they pop off the substrate. Want to create a vertical fastening? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the magnet will give way down under a noticeably lighter load. Utilizing a rubberized layer can significantly raise the stability.

12 mm	100%	8.71 kg / 19.20 pounds 8710.0 g / 85.4 N

A thin metal plate is not enough to absorb the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a too thin substrate, the flux will pass right through and the holding will be smaller. To utilize full efficiency of this magnet's power, you require a sufficiently solid piece of steel. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the product shows lower pull force. We advise picking the steel dimension from these parameters.

Standard neodymium magnets lose strength above the temperature limit. Avoid high temperatures – heat can permanently destroy this product. With increasing heat, the magnet's force briefly decreases. Refrain from using this magnet in hot environments exceeding its operating temperature limit. Too high temperature will cause permanent loss of magnetic properties.

*Important note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties sooner than long magnets. The danger warning 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 combination. The connection of two magnets creates a more powerful interaction and a further horizon of performance. Planning to create a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the pinch force is massive. The levitation is slightly lower than the connection force, but still impressive.
*Field value in repulsion mode is approximately ~0 Gs in the exact middle of the gap (due to field cancellation).
Attention: Estimates demonstrate friction force of two same neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a large risk to electronics as well as pacemakers. These magnets generate a field that prevents correct functioning of digital equipment. Remember: the invisible magnetic field passes through tissues and glass. Exceptional care must be exercised by people with hearing aids and insulin pumps. The risk also applies to: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

NdFeB products are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose speeds with massive force. Impact energy can destroy the magnet or dangerous crushing to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear safety glasses when handling with powerful specimens.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

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

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds just a fraction of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. computer case) severely weakens the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.25

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 presented product is an extremely powerful cylinder magnet, manufactured from modern NdFeB material, which, at dimensions of Ø30x5 mm, guarantees the highest energy density. The MW 30x5 / N38 model features an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 8.71 kg), this product is available off-the-shelf 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 modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 85.42 N with a weight of only 26.51 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

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 professional component. To ensure long-term durability in automation, anaerobic resins 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 professional neodymium magnets, offering a great economic balance and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø30x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 30 mm and height 5 mm. The value of 85.42 N means that the magnet is capable of holding a weight many times exceeding its own mass of 26.51 g. 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 30 mm. Such an arrangement is standard when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized diametrically if your project requires it.

Pros and cons of neodymium magnets.

Pros

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

They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
They feature excellent resistance to magnetism drop due to opposing magnetic fields,
In other words, due to the reflective surface of nickel, the element becomes visually attractive,
They show high magnetic induction at the operating surface, which improves attraction properties,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of detailed modeling and optimizing to complex needs,
Huge importance in future technologies – they are utilized in mass storage devices, electromotive mechanisms, precision medical tools, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions

Cons

What to avoid - cons of neodymium magnets and ways of using them

To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
Neodymium magnets decrease their force 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
They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited possibility of making threads in the magnet and complex shapes - recommended is a housing - magnet mounting.
Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small elements of these products are able to complicate diagnosis medical in case of swallowing.
Due to neodymium price, their price is relatively high,

Lifting parameters

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

The lifting capacity listed is a measurement result performed under standard conditions:

using a base made of mild steel, serving as a circuit closing element
with a cross-section of at least 10 mm
characterized by lack of roughness
without any insulating layer between the magnet and steel
under perpendicular force direction (90-degree angle)
at temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

Bear in mind that the application force will differ influenced by the following factors, starting with the most relevant:

Distance (betwixt the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Base massiveness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be escaped to the other side.
Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
Surface finish – full contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of neodymium magnets

Heat sensitivity

Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

Impact on smartphones

Remember: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.

Dust is flammable

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Magnetic media

Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Risk of cracking

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.

Safe operation

Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Sensitization to coating

Certain individuals suffer from a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching might lead to a rash. We strongly advise use safety gloves.

No play value

Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep out of reach of children and animals.

Pacemakers

Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Hand protection

Large magnets can smash fingers instantly. Do not place your hand betwixt two attracting surfaces.
