Pulling power weakens sharply with every mm of spacing. Remember that every additional insulation layer (e.g., contamination, paint, veneer) noticeably weakens the grip. Magnetic products operate most effectively in perfect adhesion; distance drastically cuts the force. Notice how flashily the load capacity drop, when the magnet does not touch tightly to the steel surface. When designing the mounting, avoid unnecessary gaps.

When mounting a magnet on a upright surface (e.g., a fridge), it will only hold only about 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that magnets slip faster than they pull off. Want to create a hanger? Remember that the shear force is much weaker than the maximum static pull force. On a painted metal, the element will give way down under a significantly smaller load. Utilizing a rubberized layer can effectively raise the stability.

A thin sheet is not enough to conduct the entire magnetic field, which weakens actual performance of the holder. If you mount a strong magnet to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To utilize full efficiency of this magnet's potential, you require a sufficiently solid element of metal. The saturation phenomenon means that on sheet metal structures (e.g., thin profiles), the holder holds weaker. We recommend selecting the steel cross-section from these parameters.

Standard neodymium magnets irreversibly lose power above the temperature limit. Watch out for overheating – excessive heat can irreversibly destroy this magnet. As the temperature rises, the neodymium's power briefly decreases. Do not use this magnet close to ovens higher than its operating temperature limit. Exceeding the critical threshold will result in permanent loss of magnetism.
*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Thin magnets (pancake types) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two magnets interact from a wider radius than a magnet and sheet combination. Such a system of two magnets produces a massive flux and a larger range of performance. Designing a strong closure? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the impact force is huge. The levitation is slightly lower than the connection force, but still impressive.
*Field value in repulsion mode reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Calculations show sliding force of two matching magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field is a real danger to IT equipment and medical implants. These neodymiums produce a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and housings. Special caution must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a strong collision with metal risks their cracking. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or painful pinches to fingers. Be sure to control the product during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when playing with powerful specimens.

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Shear force

*Caution: On a vertical surface, the magnet retains just approx. 20-30% of its max power.

2. Efficiency vs thickness

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

3. Power loss vs temp

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.16

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 Pc (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 Pc 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 rod magnet, produced from advanced NdFeB material, which, with dimensions of Ø25x2.5 mm, guarantees maximum efficiency. The MW 25x2.5 / N38 model is characterized by high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 2.55 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
This model is ideal for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 25.03 N with a weight of only 9.2 g, this cylindrical magnet is indispensable in electronics and wherever every gram matters.
Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 25.1 mm) using two-component epoxy glues. To ensure long-term durability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most popular standard for industrial neodymium magnets, offering an optimal price-to-power ratio and high resistance to demagnetization. If you need even stronger magnets in the same volume (Ø25x2.5), 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 25 mm and height 2.5 mm. The value of 25.03 N means that the magnet is capable of holding a weight many times exceeding its own mass of 9.2 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.
This cylinder is magnetized axially (along the height of 2.5 mm), which means that the N and S poles are located on the flat, circular surfaces. Such an arrangement is most desirable 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.

Advantages as well as disadvantages of neodymium magnets.

Strengths

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They retain full power for around ten years – the loss is just ~1% (based on simulations),
  • They retain their magnetic properties even under external field action,
  • The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
  • Magnetic induction on the working part of the magnet remains impressive,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Thanks to freedom in constructing and the ability to modify to individual projects,
  • Fundamental importance in advanced technology sectors – they are utilized in data components, electric drive systems, advanced medical instruments, as well as modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions

Weaknesses

Disadvantages of neodymium magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
  • Due to limitations in creating threads and complicated forms in magnets, we propose using cover - magnetic mechanism.
  • Potential hazard to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child health protection. Additionally, small elements of these products are able to complicate diagnosis medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Best holding force of the magnet in ideal parameters – what affects it?

The lifting capacity listed is a theoretical maximum value conducted under standard conditions:
  • on a block made of mild steel, perfectly concentrating the magnetic flux
  • with a cross-section no less than 10 mm
  • with a surface cleaned and smooth
  • under conditions of gap-free contact (surface-to-surface)
  • for force acting at a right angle (pull-off, not shear)
  • in neutral thermal conditions

Practical aspects of lifting capacity – factors

In real-world applications, the actual lifting capacity depends on many variables, presented from crucial:
  • Air gap (betwixt the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
  • Angle of force application – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
  • Base massiveness – too thin sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
  • Material type – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
  • Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
  • Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.

Safety rules for work with neodymium magnets
Crushing force

Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!

This is not a toy

Neodymium magnets are not intended for children. Eating several magnets can lead to them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.

Phone sensors

Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.

Conscious usage

Use magnets with awareness. Their huge power can shock even experienced users. Stay alert and respect their power.

Flammability

Dust produced during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Risk of cracking

Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.

Heat sensitivity

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Skin irritation risks

Medical facts indicate that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, avoid direct skin contact or opt for encased magnets.

Keep away from computers

Do not bring magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.

Life threat

Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
