Grip strength decreases significantly with every subsequent millimeter of spacing. Remember that even the smallest gap (e.g., dirt, varnish, dust) noticeably diminishes the holding power. Magnets hold optimally in perfect adhesion; air break kills the power. Observe how quickly the pull force plummet, when the product does not adhere directly to the steel surface. When designing the arrangement, discard redundant distances.

This section calculates the approximate holding capacity needed to initiate the shifting of the magnet down along a vertical metal surface (considering typical friction). The holding force is a function of the separation distance between the magnet and the surface.

When hanging a magnet on a vertical surface (e.g., a fridge), it you can count on just about 1/5 of its maximum pull force. Gravity and a weak degree of grip mean that holders 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 maximum static pull force. On a painted metal, the magnet will give way down under a much lighter cargo. Using a rubber pad can drastically improve the result.

A thin metal plate is incapable of conduct the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a weak sheet, the field will penetrate right through and the pull force will drop sharply. To achieve the maximum of this magnet's potential, you require a sufficiently solid element of steel. The saturation effect causes that on thin elements (e.g., thin profiles), the holder holds weaker. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products irreversibly lose power above the temperature limit. Watch out for overheating – excessive heat can permanently damage this magnet. As the temperature rises, the magnet's power briefly drops. Do not use this product near heat sources exceeding its safe range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Engineering note: Thermal stability is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) may lose charge permanently under lower heat stress compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and steel setup. Such a system of two magnets creates a more powerful interaction and a wider radius of action. Want to build a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the collision energy is huge. The levitation is slightly lower than the connection force, but still significant.
*The magnetic induction between like poles is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Estimates show shear force of two matching magnets (friction ~0.15 for Ni-Ni layer).

Table 7: Hazards (electronics) - precautionary measures

Powerful magnet radiation is a real danger to electronic devices and pacemakers. These NdFeB products generate a field that prevents correct functioning of digital equipment. Notice: the unseen radiation penetrates the body and plastic. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, membranes, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Neodymium magnets are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Impact energy can trigger coating fragments or painful pinches to fingers. Be sure to control the product during mounting so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when working with large magnets.

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

1. Sliding resistance

*Caution: On a vertical wall, the magnet retains just ~20% of its max power.

2. Steel thickness impact

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

3. Heat tolerance

*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) = 0.53

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 cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø70x30 mm, guarantees the highest energy density. The MW 70x30 / N38 model features a tolerance of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 144.18 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is ideal for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the pull force of 1414.37 N with a weight of only 865.9 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, we absolutely advise against 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 are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets NdFeB grade N38 are strong enough for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø70x30), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our warehouse.

This model is characterized by dimensions Ø70x30 mm, which, at a weight of 865.9 g, makes it an element with impressive magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 144.18 kg (force ~1414.37 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 70 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.

Strengths and weaknesses of rare earth magnets.

Strengths

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

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
They feature excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
By covering with a shiny coating of silver, the element acquires an modern look,
The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Thanks to modularity in designing and the ability to customize to client solutions,
Versatile presence in electronics industry – they serve a role in HDD drives, electric motors, medical devices, as well as multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
Neodymium magnets lose their strength 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 durability even at temperatures up to 230°C
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Limited ability of producing nuts in the magnet and complicated shapes - recommended is cover - magnetic holder.
Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Highest magnetic holding force – what affects it?

The load parameter shown concerns the peak performance, measured under ideal test conditions, specifically:

on a base made of mild steel, optimally conducting the magnetic field
whose thickness is min. 10 mm
with a surface cleaned and smooth
under conditions of ideal adhesion (metal-to-metal)
for force acting at a right angle (in the magnet axis)
at standard ambient temperature

Key elements affecting lifting force

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

Gap (between the magnet and the plate), because even a very small distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
Base massiveness – insufficiently thick steel does not close the flux, causing part of the power to be wasted to the other side.
Chemical composition of the base – mild steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.

Precautions when working with NdFeB magnets

Compass and GPS

Remember: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.

Dust explosion hazard

Powder generated during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Danger to the youngest

Absolutely store magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are life-threatening.

Operating temperature

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

Conscious usage

Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Allergy Warning

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease handling magnets and use protective gear.

Protective goggles

Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Bone fractures

Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Life threat

People with a ICD must maintain an safe separation from magnets. The magnetism can disrupt the functioning of the life-saving device.

Protect data

Do not bring magnets close to a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
