Magnetic force weakens significantly per each millimeter of distance. Note that even a very thin break (e.g., dirt, paint, rust) noticeably diminishes the holding power. Magnetic products operate optimally at the point of direct contact; air break drastically cuts the power. Observe how quickly the load capacity plummet, when the product does not adhere flatly to the metal substrate. When planning the assembly, discard redundant distances.

The table below calculates the approximate weight limit required to initiate the sliding of the magnet down on a vertical steel plate (considering typical friction). This value varies with the distance between the magnet and the metal.

When placing a holder on a upright surface (e.g., a car body), it will only hold barely about 1/5 of its nominal power. Gravity as well as a low friction coefficient influence the fact that magnets slide down faster than they pull off. Want to create a vertical fastening? Note that the shear force is significantly lower than the maximum static pull force. On a painted metal, the magnet will slide down under a noticeably lighter load. Utilizing a rubberized layer can effectively improve the result.

A too thin steel is incapable of absorb the full magnetic flux, which squanders power of the holder. If you mount a strong magnet to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To achieve 100% of this magnet's power, you require a sufficiently solid backing of metal. The material oversaturation means that on sheet metal structures (e.g., appliance housings), the magnet holds weaker. We advise picking the steel thickness according to the table below.

Standard neodymium magnets lose parameters past the thermal threshold. Protect against heat – high temperature can irreversibly demagnetize this magnet. As the temperature rises, the magnet's power temporarily decreases. Refrain from using this magnet close to heaters exceeding its safe range. Exceeding the critical threshold will lead to destruction of magnetic properties.
*Important note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and sheet setup. Such a system of magnet-to-magnet generates a stronger field and a wider radius of action. Planning to create a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the impact force is massive. The repulsion force is a bit weaker than the connection force, but still significant.
*Flux density in repulsion mode reaches ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Estimates demonstrate friction force of a pair of matching magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field is a large risk to electronic devices as well as medical implants. These neodymiums generate a flux that disrupts operation of sensitive medical devices. Remember: the unseen radiation acts through matter and glass. Special caution must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

NdFeB products are very brittle – a collision with steel can result in shattering. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can cause material chips or injury to skin. Hold the magnet firmly during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when playing with large magnets.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.
1. Wall mount (shear)

*Note: On a vertical surface, the magnet holds merely a fraction of its perpendicular strength.

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Temperature resistance

*For standard magnets, 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 a very strong cylinder magnet, composed of durable NdFeB material, which, at dimensions of Ø10x6 mm, guarantees optimal power. The MW 10x6 / N38 component is characterized by a tolerance of ±0.1mm and professional build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with significant force (approx. 3.38 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 33.12 N with a weight of only 3.53 g, this cylindrical magnet is indispensable in miniature devices 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., 10.1 mm) using two-component epoxy glues. To ensure long-term durability in industry, anaerobic resins are used, which are safe for nickel 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 high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø10x6), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
This model is characterized by dimensions Ø10x6 mm, which, at a weight of 3.53 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 3.38 kg (force ~33.12 N), which, with such compact dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
This cylinder is magnetized axially (along the height of 6 mm), which means that the N and S poles are located on the flat, circular surfaces. Thanks to this, the magnet can be easily glued into a hole and achieve a strong field on the front surface. On request, we can also produce versions magnetized through the diameter if your project requires it.

Advantages and disadvantages of neodymium magnets.

Pros

Besides their immense pulling force, neodymium magnets offer the following advantages:
  • They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
  • They are resistant to demagnetization induced by presence of other magnetic fields,
  • The use of an refined coating of noble metals (nickel, gold, silver) causes the element to look better,
  • The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
  • Due to the possibility of flexible shaping and adaptation to individualized projects, neodymium magnets can be produced in a variety of geometric configurations, which amplifies use scope,
  • Universal use in electronics industry – they find application in HDD drives, drive modules, precision medical tools, and modern systems.
  • Thanks to their power density, small magnets offer high operating force, in miniature format,

Limitations

What to avoid - cons of neodymium magnets and ways of using them
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. 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 power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in realizing threads and complicated forms in magnets, we recommend using cover - magnetic holder.
  • Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Additionally, small elements of these devices can complicate diagnosis medical in case of swallowing.
  • Due to complex production process, their price exceeds standard values,

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?

The force parameter is a theoretical maximum value executed under specific, ideal conditions:
  • on a plate made of structural steel, optimally conducting the magnetic field
  • with a thickness of at least 10 mm
  • characterized by smoothness
  • with zero gap (without coatings)
  • for force acting at a right angle (pull-off, not shear)
  • at conditions approx. 20°C

Determinants of lifting force in real conditions

Please note that the magnet holding may be lower influenced by the following factors, starting with the most relevant:
  • Clearance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
  • Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
  • Steel grade – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
  • Surface condition – ground elements ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
  • Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate lowers the load capacity.

Warnings
Bodily injuries

Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Medical implants

People with a pacemaker have to maintain an large gap from magnets. The magnetic field can disrupt the operation of the implant.

Demagnetization risk

Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.

Combustion hazard

Dust produced during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.

Magnetic media
