Pulling power drops sharply with every subsequent millimeter of spacing. Remember that even the smallest gap (e.g., contamination, paint, rust) noticeably weakens the grip. Neodymiums hold most effectively during direct contact; air break drastically cuts the force. See how flashily the load capacity fall, when the product does not adhere directly to the steel surface. When designing the arrangement, discard unnecessary gaps.

The following data calculates the approximate force sufficient to initiate the slippage of the magnet vertically against a vertical steel wall (assuming typical friction coefficient). This parameter depends on the distance between the magnet and the metal.

When hanging a element on a vertical surface (e.g., a fridge), it you can count on only about 20%-30% of its nominal power. Gravitational force and a low friction coefficient influence the fact that magnets slide down easier than they pop off the substrate. Want to create a hanger? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will slip down under a noticeably lighter weight. Application of an anti-slip coating can drastically raise the stability.

A thin sheet is incapable of take in the entire magnetic field, which wastes potential of the magnet. Should you install a neodymium to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To squeeze full efficiency of this neodymium's potential, you need a suitably thick element of metal. The saturation phenomenon means that on sheet metal structures (e.g., thin profiles), the holder shows lower pull force. We suggest choosing the steel thickness according to the table below.

Classic neodymiums change their properties parameters above the temperature limit. Watch out for overheating – high temperature can permanently damage this product. With every degree above norm, the neodymium's power momentarily drops. Refrain from using this product near heat sources exceeding its operating temperature limit. Too high temperature will cause irreversible degradation of magnetism.
*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) may lose charge permanently sooner compared to rod magnets. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two magnets interact from a wider radius than a magnet and steel combination. The setup of magnet-to-magnet generates a stronger field and a larger range of action. Want to build a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still significant.
*Field value in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (due to field cancellation).
Note: Figures apply to shear force of a pair of identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a serious hazard to electronic devices and pacemakers. These neodymiums produce a flux that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field penetrates the body and glass. Increased vigilance must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

NdFeB products are prone to chipping – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or dangerous crushing to fingers. Always hold the magnet during mounting 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 working with powerful specimens.

Corrosion 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

*Caution: On a vertical wall, the magnet holds only a fraction of its max power.

2. Steel saturation

*Thin steel (e.g. computer case) significantly reduces the holding force.

3. Power loss vs temp

*For N38 grade, the safety limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.29

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 offered product is an incredibly powerful rod magnet, produced from modern NdFeB material, which, with dimensions of Ø25x5 mm, guarantees optimal power. The MW 25x5 / N38AH component features high dimensional repeatability and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 7.29 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
This model is created for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 71.47 N with a weight of only 18.41 g, this rod is indispensable in electronics and wherever every gram matters.
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 precision component. To ensure long-term durability in industry, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Magnets NdFeB grade N38 are strong enough for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø25x5), 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 Ø25x5 mm, which, at a weight of 18.41 g, makes it an element with impressive magnetic energy density. The value of 71.47 N means that the magnet is capable of holding a weight many times exceeding its own mass of 18.41 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 5 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 diametrically if your project requires it.

Pros and cons of rare earth magnets.

Strengths

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
  • They do not lose power, even over approximately ten years – the drop in strength is only ~1% (based on measurements),
  • They retain their magnetic properties even under strong external field,
  • In other words, due to the shiny layer of gold, the element becomes visually attractive,
  • They show high magnetic induction at the operating surface, which affects their effectiveness,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
  • Possibility of detailed machining and adapting to concrete conditions,
  • Key role in electronics industry – they are commonly used in data components, electric motors, diagnostic systems, as well as modern systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

What to avoid - cons of neodymium magnets and proposals for their use:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
  • When exposed to high temperature, neodymium magnets experience 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 usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
  • We recommend a housing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
  • Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical after entering the body.
  • With large orders the cost of neodymium magnets is a challenge,

Lifting parameters

Highest magnetic holding force – what contributes to it?

The declared magnet strength represents the limit force, obtained under optimal environment, specifically:
  • using a sheet made of low-carbon steel, acting as a ideal flux conductor
  • with a thickness of at least 10 mm
  • with an polished touching surface
  • with zero gap (without coatings)
  • under vertical application of breakaway force (90-degree angle)
  • in stable room temperature

Impact of factors on magnetic holding capacity in practice

In practice, the actual lifting capacity is determined by several key aspects, listed from crucial:
  • Clearance – existence of any layer (paint, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Material type – the best choice is high-permeability steel. Cast iron may attract less.
  • Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
  • Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.

Warnings
Maximum temperature

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.

Powerful field

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

Electronic devices

Do not bring magnets near a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Swallowing risk

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

Machining danger

Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Nickel allergy

A percentage of the population experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Extended handling might lead to a rash. We suggest use safety gloves.

Precision electronics

A strong magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Maintain magnets near a device to avoid damaging the sensors.

Physical harm

Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!

Material brittleness

Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Implant safety

For implant holders: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
