Magnetic force decreases significantly per each millimeter of spacing. Remember that every additional insulation layer (e.g., dirt, varnish, dust) significantly diminishes the holding power. Magnetic products work optimally in perfect adhesion; distance drastically cuts the power. Notice how rapidly the pull force plummet, when the magnet does not touch directly to the steel surface. When calculating the mounting, discard additional spacers.

When placing a holder on a vertical surface (e.g., a board), it will maintain only approx. 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip cause that magnets slip easier than they pop off the substrate. Planning a hanger? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a significantly smaller weight. Utilizing a rubberized layer can significantly improve the result.

A thin metal plate cannot take in the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a weak sheet, the field will penetrate right through and the holding will be smaller. To utilize 100% of this magnet's power, you need a suitably thick element of metal. The saturation effect causes that on delicate walls (e.g., car bodies), the product holds weaker. We recommend selecting the steel cross-section from these parameters.

Ordinary NdFeB products change their properties power past the thermal threshold. Avoid high temperatures – high temperature can irreversibly destroy this magnet. With increasing heat, the neodymium's power temporarily lowers. Refrain from using this product close to ovens exceeding its safe range. Exceeding the critical threshold will cause permanent loss of magnetic properties.
*Technical advisory: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than long magnets. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and steel combination. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the impact force is massive. The repulsion force is slightly lower than the attraction, but still significant.
*Flux density for N-N configuration drops to ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Attention: Figures show shear force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Magnetic elements are very brittle – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when playing 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.
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 holds only approx. 20-30% of its nominal pull.

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Temperature resistance

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.66

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 cylinder magnet, made from modern NdFeB material, which, with dimensions of Ø5x3 mm, guarantees maximum efficiency. The MW 5x3 / N38 model features high dimensional repeatability and industrial build quality, making it an excellent solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 0.84 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
It successfully proves itself in modeling, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 8.25 N with a weight of only 0.44 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.
Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Magnets N38 are suitable 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 (Ø5x3), 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 Ø5x3 mm, which, at a weight of 0.44 g, makes it an element with high magnetic energy density. The key parameter here is the lifting capacity amounting to approximately 0.84 kg (force ~8.25 N), which, with such defined 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.
This cylinder is magnetized axially (along the height of 3 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 and disadvantages of rare earth magnets.

Pros

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:
  • Their strength is maintained, and after approximately ten years it drops only by ~1% (according to research),
  • Magnets very well defend themselves against loss of magnetization caused by external fields,
  • By applying a shiny coating of gold, the element gains an aesthetic look,
  • Magnets are characterized by very high magnetic induction on the working surface,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • Considering the possibility of flexible forming and customization to specialized projects, NdFeB magnets can be manufactured in a variety of shapes and sizes, which amplifies use scope,
  • Fundamental importance in advanced technology sectors – they are used in HDD drives, brushless drives, medical equipment, as well as industrial machines.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Characteristics of disadvantages of neodymium magnets: application proposals
  • At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • 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
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in creating threads and complicated forms in magnets, we recommend using cover - magnetic holder.
  • Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, small elements 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

Pull force analysis

Detachment force of the magnet in optimal conditions – what affects it?

Breakaway force was defined for ideal contact conditions, assuming:
  • on a block made of structural steel, optimally conducting the magnetic field
  • whose thickness reaches at least 10 mm
  • with a surface perfectly flat
  • under conditions of no distance (metal-to-metal)
  • during pulling in a direction vertical to the plane
  • in stable room temperature

Magnet lifting force in use – key factors

In real-world applications, the real power results from several key aspects, presented from crucial:
  • Distance – the presence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
  • Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
  • Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
  • Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
  • Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Safety rules for work with NdFeB magnets
Crushing force

Danger of trauma: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.

Electronic devices

Intense magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Threat to navigation

GPS units and smartphones are extremely sensitive to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.

Pacemakers

Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.

Warning for allergy sufferers

Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.

Do not give to children

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

Do not drill into magnets

Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Heat sensitivity

Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.

Protective goggles

Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. We recommend safety glasses.
