1. Sliding resistance

*Warning: On a vertical wall, the magnet holds merely approx. 20-30% of its nominal pull.

2. Steel saturation

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

3. Temperature resistance

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

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

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

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.

This product is an extremely powerful cylindrical magnet, composed of advanced NdFeB material, which, at dimensions of Ø10x2 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and industrial build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 1.27 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 12.50 N with a weight of only 1.18 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.
Due to the delicate structure of the ceramic sinter, 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 automation, anaerobic resins are used, which do not react with the nickel coating and fill the gap, guaranteeing high repeatability of the connection.
Grade N38 is the most frequently chosen 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 (Ø10x2), 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 Ø10x2 mm, which, at a weight of 1.18 g, makes it an element with high magnetic energy density. The value of 12.50 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.18 g. The product has a [NiCuNi] coating, which protects the surface 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 10 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 through the diameter if your project requires it.

Advantages as well as disadvantages of rare earth magnets.

Advantages

Besides their immense field intensity, neodymium magnets offer the following advantages:
  • Their power is durable, and after approximately 10 years it drops only by ~1% (theoretically),
  • Neodymium magnets are distinguished by remarkably resistant to magnetic field loss caused by external interference,
  • In other words, due to the smooth layer of silver, the element is aesthetically pleasing,
  • Magnets exhibit exceptionally strong magnetic induction on the outer side,
  • Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
  • Due to the ability of precise shaping and customization to custom projects, NdFeB magnets can be modeled in a variety of forms and dimensions, which increases their versatility,
  • Huge importance in future technologies – they find application in mass storage devices, electric motors, medical devices, as well as technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in miniature devices

Disadvantages

Drawbacks and weaknesses of neodymium magnets and ways of using them
  • To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • When exposed to high temperature, neodymium magnets experience a drop in strength. 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
  • When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
  • We recommend a housing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
  • Health risk related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these products are able to disrupt the diagnostic process medical after entering the body.
  • Due to neodymium price, their price exceeds standard values,

Holding force characteristics

Magnetic strength at its maximum – what contributes to it?

The lifting capacity listed is a result of laboratory testing executed under specific, ideal conditions:
  • using a plate made of low-carbon steel, acting as a magnetic yoke
  • with a thickness of at least 10 mm
  • with an ground touching surface
  • under conditions of no distance (surface-to-surface)
  • for force applied at a right angle (in the magnet axis)
  • at standard ambient temperature

Lifting capacity in practice – influencing factors

During everyday use, the actual lifting capacity depends on many variables, listed from most significant:
  • Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
  • Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
  • Material type – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
  • Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
  • Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.

Safety rules for work with NdFeB magnets
Serious injuries

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

Threat to navigation

Remember: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your mobile, device, and navigation systems.

Operating temperature

Watch the temperature. Heating the magnet to high heat will destroy its properties and pulling force.

Product not for children

Absolutely keep magnets away from children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are very dangerous.

Fire risk

Dust created during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop handling magnets and wear gloves.

Danger to pacemakers

Individuals with a ICD must maintain an large gap from magnets. The magnetism can interfere with the operation of the implant.

Magnets are brittle

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

Conscious usage

Handle magnets consciously. Their huge power can surprise even professionals. Plan your moves and do not underestimate their power.

Threat to electronics

Do not bring magnets near a wallet, computer, or screen. The magnetic field can destroy these devices and erase data from cards.
