Pulling power drops significantly with every mm of spacing. Note that even the smallest gap (e.g., dirt, paint, dust) strongly diminishes the holding power. Magnets work most effectively during direct contact; gap weakens the force. Notice how flashily the pull force drop, when the product does not touch directly to the steel surface. When calculating the arrangement, avoid additional spacers.

The table below presents the theoretical force needed to initiate the downward movement of the magnet down along a upright steel plate (considering typical friction). This parameter depends on the air gap between the magnet and the metal.

When hanging a holder on a upright surface (e.g., a board), it you can count on barely approx. 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip mean that magnets move down faster than they pull off. Planning a hanger? Note that the sliding force is much weaker than the maximum static pull force. On a painted metal, the magnet will slide down under a significantly smaller cargo. Using a rubber layer can drastically improve the result.

A thin metal plate is incapable of absorb the entire magnetic field, which weakens actual performance of the holder. Should you mount a strong magnet to a weak sheet, the magnetism 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 backing of metal. The saturation phenomenon means that on thin elements (e.g., car bodies), the product holds weaker. We suggest choosing the steel thickness according to the table below.

Ordinary NdFeB products lose parameters past the thermal threshold. Avoid high temperatures – heat can irreversibly demagnetize this product. As the temperature rises, the neodymium's power momentarily drops. Refrain from using this product near heat sources higher than its working range. Ignoring the limit will cause irreversible degradation of magnetism.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) are more susceptible to demagnetization sooner than long magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a magnet and sheet setup. Such a system of magnet-to-magnet produces a massive flux and a larger range of action. Want to build a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when bringing together two magnets, the pinch force is extreme. The levitation is slightly lower than the attraction, but still significant.
*Field value for N-N configuration reaches ~0 Gs in the exact middle between the magnets (due to field cancellation).
* Figures show sliding force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field poses a serious hazard to electronic devices as well as medical implants. These magnets produce a field that disrupts operation of digital equipment. Notice: the unseen radiation penetrates the body and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MW 45x30 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	16.76 km/h (4.66 m/s)	3.88 J
30 mm	24.77 km/h (6.88 m/s)	8.47 J
50 mm	31.50 km/h (8.75 m/s)	13.70 J
100 mm	44.44 km/h (12.34 m/s)	27.26 J

Neodymium magnets are delicate – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Impact energy can trigger coating fragments or injury to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when playing 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!

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Caution: On a vertical surface, the magnet holds just approx. 20-30% of its nominal pull.

2. Plate thickness effect

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

3. Thermal stability

*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) = 0.71

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.

MW 15x1 / N38 - cylindrical magnet

0.800 ZŁ brutto / pcs

This product is an exceptionally strong cylinder magnet, composed of advanced NdFeB material, which, at dimensions of Ø45x30 mm, guarantees the highest energy density. The MW 45x30 / N38 model is characterized by an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 69.46 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard 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 high power of 681.39 N with a weight of only 357.85 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

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., 45.1 mm) using two-component epoxy glues. To ensure stability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.

Magnets N38 are suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø45x30), 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 Ø45x30 mm, which, at a weight of 357.85 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 69.46 kg (force ~681.39 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 30 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 neodymium magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
Magnets perfectly resist against demagnetization caused by foreign field sources,
By using a shiny coating of silver, the element acquires an aesthetic look,
Magnetic induction on the working part of the magnet is maximum,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
Thanks to freedom in forming and the capacity to adapt to individual projects,
Fundamental importance in innovative solutions – they find application in magnetic memories, electric motors, advanced medical instruments, also other advanced devices.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Limitations

Problematic aspects of neodymium magnets: weaknesses and usage proposals

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
We recommend a housing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small components of these magnets can be problematic in diagnostics medical after entering the body.
With mass production the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

Breakaway force is the result of a measurement for the most favorable conditions, taking into account:

on a base made of mild steel, perfectly concentrating the magnetic field
with a thickness minimum 10 mm
with a plane cleaned and smooth
with zero gap (without impurities)
during pulling in a direction perpendicular to the plane
in neutral thermal conditions

Lifting capacity in practice – influencing factors

In real-world applications, the real power results from a number of factors, presented from most significant:

Air gap (between the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
Angle of force application – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
Base massiveness – too thin sheet does not close the flux, causing part of the power to be escaped to the other side.
Steel grade – ideal substrate is pure iron steel. Cast iron may attract less.
Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.

Warnings

Pacemakers

Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Protective goggles

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Mechanical processing

Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.

Do not underestimate power

Handle with care. Rare earth magnets act from a distance and connect with massive power, often faster than you can react.

Hand protection

Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Choking Hazard

Always store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are very dangerous.

Permanent damage

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Protect data

Device Safety: Strong magnets can damage payment cards and delicate electronics (heart implants, hearing aids, timepieces).

Metal Allergy

A percentage of the population experience a contact allergy to nickel, which is the common plating for NdFeB magnets. Extended handling might lead to skin redness. We recommend use safety gloves.

Phone sensors

Note: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, device, and GPS.
