Grip strength weakens drastically per each millimeter of gap. Keep in mind that even the smallest gap (e.g., dirt, varnish, rust) noticeably weakens the grip. Magnets operate most effectively during direct contact; gap weakens the force. Analyze how rapidly the parameters plummet, when the magnet does not touch flatly to the steel surface. When designing the arrangement, discard redundant distances.

The table below defines the theoretical weight limit necessary to cause the shifting of the magnet downwards along a upright metal surface (assuming standard friction). The holding force is a function of the gap size between the magnet and the surface.

When mounting a holder on a vertical plane (e.g., a fridge), it will only hold just approx. 20%-30% of nominal attraction strength. Gravitational force and a weak degree of grip influence the fact that magnets slide down easier than they pop off the substrate. Want to create a vertical fastening? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a significantly smaller cargo. Utilizing a rubberized layer can significantly raise the stability.

A thin metal plate is incapable of focus the full magnetic flux, which wastes potential of the holder. Should you attach a powerful product to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To achieve 100% of this magnet's power, you need a suitably thick piece of metal. The saturation effect causes that on delicate walls (e.g., appliance housings), the holder works worse. We advise picking the steel cross-section according to the table below.

Standard neodymium magnets change their properties strength above the temperature limit. Avoid high temperatures – excessive heat can permanently demagnetize this magnet. With increasing heat, the neodymium's capacity momentarily decreases. Do not use this product close to ovens higher than its working range. Ignoring the limit will result in permanent loss of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) are more susceptible to demagnetization at lower temperatures than taller cylinders. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and steel setup. Such a system of two magnets creates a more powerful interaction and a further horizon of action. Planning to create a solid fastener? Apply two magnets instead of a neodymium and a steel. Be careful that when bringing together two magnets, the pinch force is extreme. The repulsion force is marginally weaker than the attraction, but still significant.
*Field value for N-N configuration is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).
Note: Estimates refer to friction force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a large risk to IT equipment and pacemakers. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and housings. Exceptional care must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - warning
MW 45x15 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	20.09 km/h (5.58 m/s)	2.79 J
30 mm	29.29 km/h (8.14 m/s)	5.92 J
50 mm	37.23 km/h (10.34 m/s)	9.57 J
100 mm	52.54 km/h (14.59 m/s)	19.05 J

NdFeB products are very brittle – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can destroy the magnet or injury to fingers. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when handling with large magnets.

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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Warning: On a vertical wall, the magnet holds merely ~20% of its max power.

2. Steel saturation

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

3. Power loss vs temp

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.44

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 an extremely powerful cylindrical magnet, made from durable NdFeB material, which, with dimensions of Ø45x15 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 48.55 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

It successfully proves itself in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 476.32 N with a weight of only 178.92 g, this cylindrical magnet is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 45.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.

Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø45x15), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø45x15 mm, which, at a weight of 178.92 g, makes it an element with impressive magnetic energy density. The value of 476.32 N means that the magnet is capable of holding a weight many times exceeding its own mass of 178.92 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This rod magnet is magnetized axially (along the height of 15 mm), which means that the N and S poles are located on the flat, circular surfaces. 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 through the diameter if your project requires it.

Strengths as well as weaknesses of neodymium magnets.

Pros

Besides their immense strength, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
They possess excellent resistance to magnetic field loss due to opposing magnetic fields,
Thanks to the shimmering finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
Neodymium magnets ensure maximum magnetic induction on a contact point, which allows for strong attraction,
Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
Thanks to flexibility in designing and the capacity to customize to complex applications,
Key role in future technologies – they are commonly used in HDD drives, electric drive systems, medical equipment, as well as complex engineering applications.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:

At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 very resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in creating nuts and complex shapes in magnets, we propose using cover - magnetic mount.
Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Breakaway strength of the magnet in ideal conditions – what contributes to it?

Holding force of 48.55 kg is a result of laboratory testing conducted under standard conditions:

using a sheet made of low-carbon steel, acting as a magnetic yoke
with a thickness no less than 10 mm
with a surface cleaned and smooth
without the slightest air gap between the magnet and steel
under axial force direction (90-degree angle)
at temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

It is worth knowing that the working load will differ influenced by elements below, in order of importance:

Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Direction of force – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Material composition – different alloys reacts the same. High carbon content worsen the attraction effect.
Surface finish – full contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.

Precautions when working with neodymium magnets

Nickel coating and allergies

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop working with magnets and wear gloves.

Electronic hazard

Intense magnetic fields can destroy records on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.

GPS and phone interference

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

Fragile material

NdFeB magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets will cause them breaking into small pieces.

Combustion hazard

Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Maximum temperature

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Implant safety

For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.

Crushing force

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

Swallowing risk

Absolutely store magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are fatal.

Handling guide

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

Warning! More info about risks in the article: Magnet Safety Guide.
