Grip strength drops significantly with every subsequent millimeter of distance. Note that even a very thin break (e.g., dirt, paint, rust) significantly weakens the grip. Magnets work strongest at the point of direct contact; air break drastically cuts the power. Notice how quickly the pull force plummet, when the magnet does not touch tightly to the steel surface. When planning the assembly, avoid unnecessary gaps.

The table below indicates the estimated weight limit needed to initiate the shifting of the magnet down against a upright steel wall (assuming standard friction). This value varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull

Raw steel	µ = 0.3 30% Nominalnej Siły	20.20 kg / 44.53 lbs 20199.0 g / 198.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	13.47 kg / 29.69 lbs 13466.0 g / 132.1 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	33.67 kg / 74.22 lbs 33665.0 g / 330.3 N

When hanging a element on a vertical plane (e.g., a board), it will only hold only approx. 20%-30% of its maximum pull force. Gravitational force and a low friction coefficient mean that holders move down easier than they pop off the substrate. Planning a hanger? Consider that the sliding force is much weaker than the maximum static pull force. On a painted metal, the holder will slide down under a significantly smaller cargo. Application of an anti-slip layer can significantly increase the grip.

12 mm	100%	67.33 kg / 148.44 lbs 67330.0 g / 660.5 N

A too thin steel is not enough to take in the full magnetic flux, which wastes potential of the holder. Should you mount a strong magnet to a thin surface, the field will pass right through and the pull force will drop sharply. To squeeze 100% of this neodymium's potential, you need a suitably thick element of steel. The saturation phenomenon causes that on thin elements (e.g., appliance housings), the product works worse. We advise picking the steel thickness from these parameters.

Standard neodymium magnets irreversibly lose strength above the temperature limit. Protect against heat – heat can irreversibly damage this magnet. With increasing heat, the magnet's force briefly drops. Refrain from using this product near heat sources higher than its operating temperature limit. Too high temperature will result in permanent loss of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) risk losing magnetic properties at lower temperatures than long magnets. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel combination. The connection of magnet-to-magnet generates a stronger field and a further horizon of performance. Designing a strong closure? Apply two magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the impact force is extreme. The levitation is marginally weaker than the attraction, but still impressive.
*Flux density for N-N configuration reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Important: Estimates show shear force of two identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a serious hazard to electronic devices as well as pacemakers. These NdFeB products produce a field that destroys function of digital equipment. Remember: the unseen radiation penetrates the body and housings. Exceptional care must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or injury to fingers. Be sure to control the product during installation so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the magnet. Wear eye protection when playing with powerful specimens.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Warning: On a vertical wall, the magnet retains just ~20% of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

*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) = 0.63

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 exceptionally strong cylindrical magnet, composed of modern NdFeB material, which, at dimensions of Ø45x25 mm, guarantees optimal power. The MW 45x25 / N38 component features high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 67.33 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 660.51 N with a weight of only 298.21 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.

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 stability in industry, anaerobic resins 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 a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø45x25), 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 45 mm and height 25 mm. The value of 660.51 N means that the magnet is capable of holding a weight many times exceeding its own mass of 298.21 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 25 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.

Advantages as well as disadvantages of rare earth magnets.

Advantages

Besides their exceptional magnetic power, neodymium magnets offer the following advantages:

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
Magnets perfectly resist against demagnetization caused by ambient magnetic noise,
By using a lustrous coating of nickel, the element presents an professional look,
Magnets have huge magnetic induction on the working surface,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
Thanks to versatility in designing and the capacity to modify to specific needs,
Versatile presence in advanced technology sectors – they serve a role in computer drives, electric motors, medical equipment, also industrial machines.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Weaknesses

Characteristics of disadvantages of neodymium magnets: tips and applications.

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects 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 very resistant to heat
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We suggest a housing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
With mass production the cost of neodymium magnets is a challenge,

Pull force analysis

Maximum lifting capacity of the magnet – what it depends on?

Magnet power is the result of a measurement for ideal contact conditions, taking into account:

on a plate made of structural steel, perfectly concentrating the magnetic flux
whose thickness equals approx. 10 mm
with an ideally smooth contact surface
under conditions of gap-free contact (metal-to-metal)
under axial force direction (90-degree angle)
in neutral thermal conditions

Lifting capacity in real conditions – factors

In real-world applications, the real power depends on several key aspects, ranked from crucial:

Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.

Precautions when working with neodymium magnets

Swallowing risk

Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are very dangerous.

Bodily injuries

Large magnets can smash fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.

Sensitization to coating

Certain individuals suffer from a contact allergy to nickel, which is the common plating for neodymium magnets. Frequent touching can result in skin redness. It is best to use protective gloves.

Compass and GPS

GPS units and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.

Medical interference

For implant holders: Powerful magnets affect electronics. Maintain at least 30 cm distance or ask another person to handle the magnets.

Keep away from computers

Avoid bringing magnets near a purse, computer, or screen. The magnetic field can destroy these devices and erase data from cards.

Dust explosion hazard

Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.

Heat warning

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.

Eye protection

Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Handling rules

Exercise caution. Neodymium magnets attract from a long distance and connect with huge force, often quicker than you can move away.
