1. Vertical hold

*Note: On a vertical surface, the magnet retains just ~20% of its nominal pull.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) drastically reduces the holding force.

3. Heat tolerance

*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) = 0.89

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 a very strong cylindrical magnet, manufactured from modern NdFeB material, which, with dimensions of Ø10x10 mm, guarantees maximum efficiency. The MW 10x10 / N38 model is characterized by high dimensional repeatability and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 3.18 kg), this product is in stock from our European logistics center, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is perfect for building electric motors, advanced Hall effect sensors, and efficient magnetic separators, where field concentration on a small surface counts. Thanks to the high power of 31.15 N with a weight of only 5.89 g, this cylindrical magnet is indispensable in miniature devices 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 professional component. To ensure long-term durability in industry, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Grade N38 is the most frequently chosen standard for industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø10x10), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our store.
This model is characterized by dimensions Ø10x10 mm, which, at a weight of 5.89 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 3.18 kg (force ~31.15 N), which, with such compact 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.
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. 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 diametrically if your project requires it.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Pros
In addition to their long-term stability, neodymium magnets provide the following advantages:
  • Their power is maintained, and after around ten years it drops only by ~1% (theoretically),
  • They are resistant to demagnetization induced by external field influence,
  • Thanks to the glossy finish, the coating of nickel, gold-plated, or silver gives an visually attractive appearance,
  • Neodymium magnets create maximum magnetic induction on a small surface, which allows for strong attraction,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Possibility of precise modeling as well as adapting to defined conditions,
  • Fundamental importance in advanced technology sectors – they are used in magnetic memories, drive modules, medical devices, as well as multitasking production systems.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
Disadvantages of neodymium magnets:
  • At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • Due to limitations in creating nuts and complicated shapes in magnets, we propose using casing - magnetic holder.
  • Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can complicate diagnosis medical when they are in the body.
  • Due to expensive raw materials, their price exceeds standard values,

Lifting parameters

Detachment force of the magnet in optimal conditionswhat contributes to it?
The load parameter shown represents the limit force, recorded under ideal test conditions, namely:
  • on a block made of structural steel, effectively closing the magnetic flux
  • whose thickness reaches at least 10 mm
  • characterized by even structure
  • with total lack of distance (no paint)
  • for force acting at a right angle (in the magnet axis)
  • at standard ambient temperature
Practical aspects of lifting capacity – factors
It is worth knowing that the working load may be lower depending on the following factors, starting with the most relevant:
  • Gap (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
  • Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
  • Plate texture – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
  • Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was determined using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

H&S for magnets
Fragile material

Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Demagnetization risk

Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and strength.

Do not drill into magnets

Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.

GPS and phone interference

A strong magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Maintain magnets close to a device to prevent damaging the sensors.

Skin irritation risks

Some people experience a contact allergy to Ni, which is the common plating for neodymium magnets. Extended handling might lead to skin redness. We suggest wear protective gloves.

Handling rules

Handle with care. Neodymium magnets attract from a distance and connect with huge force, often quicker than you can react.

Warning for heart patients

Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

Product not for children

Always store magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.

Serious injuries

Risk of injury: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.

Magnetic media

Data protection: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
