Frequently asked questions

Where can I buy strong cylindrical neodymium magnets?
See the available cylinders in the DHIT catalogue. Compare dimensions, grade and the pull-force value on each product card; grade alone does not determine the pull force of a finished magnet.
Can a small cylindrical magnet provide a strong grip for precise workshop work?
Yes, but size alone is not enough to predict the result. Geometry, the steel surface and the direction of load affect the grip. Compare the specifications of the selected dimensions on their product cards.
Which cylindrical magnet can work at a higher temperature?
Check the operating-temperature limit of the particular model rather than assuming one limit for all N grades. The offered N52 models are rated up to 60°C. For hotter applications, ask for a product with a confirmed specification for the actual working temperature.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains merely a fraction of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) significantly reduces the holding force.

3. Heat tolerance

N38: the maximum material working temperature is 80°C. Permitted conditions also depend on the shape and magnetic circuit.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.59

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.

Other deals

This product is an incredibly powerful cylindrical magnet, made from durable NdFeB material, which, at dimensions of Ø6x3 mm, guarantees the highest energy density. This specific item features an accuracy of ±0.1mm and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.15 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing an aesthetic appearance and durability for years.
It finds application in modeling, advanced automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 11.23 N with a weight of only 32 g, this rod is indispensable in miniature devices and wherever every gram matters.
Since our magnets have a very precise dimensions, the best method is to glue them into holes with a slightly larger diameter (e.g., 6.1 mm) using epoxy glues. 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.
Choose the material grade together with the dimensions and working conditions. A grade designation alone does not determine the pull force of the finished magnet. Check the properties and working temperature of this specific model on its product card; contact us before ordering for an unusual application.
The presented product is a neodymium magnet with precisely defined parameters: diameter 6 mm and height 3 mm. The value of 11.23 N means that the magnet is capable of holding a weight many times exceeding its own mass of 32 g. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 3 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 diametrically if your project requires it.

Strengths as well as weaknesses of rare earth magnets.

Advantages

Apart from their superior magnetic energy, neodymium magnets have these key benefits:
  • They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
  • They retain their magnetic properties even under external field action,
  • By using a lustrous coating of gold, the element has an modern look,
  • Magnetic induction on the top side of the magnet remains impressive,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to modularity in shaping and the ability to modify to individual projects,
  • Versatile presence in future technologies – they find application in mass storage devices, electric drive systems, precision medical tools, and modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in small systems

Disadvantages

What to avoid - cons of neodymium magnets and proposals for their use:
  • To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
  • They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing threads and complicated shapes in magnets, we propose using cover - magnetic holder.
  • Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
  • Due to expensive raw materials, their price is higher than average,

Lifting parameters

Best holding force of the magnet in ideal parameters – what it depends on?

The specified lifting capacity represents the limit force, measured under ideal test conditions, namely:
  • using a plate made of high-permeability steel, acting as a circuit closing element
  • possessing a thickness of min. 10 mm to ensure full flux closure
  • characterized by lack of roughness
  • with zero gap (without impurities)
  • under axial force direction (90-degree angle)
  • at temperature approx. 20 degrees Celsius

Impact of factors on magnetic holding capacity in practice

Effective lifting capacity is influenced by working environment parameters, including (from priority):
  • Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Load vector – highest force is reached only during perpendicular pulling. The shear force of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Steel type – mild steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
  • Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
  • Temperature – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

H&S for magnets
Compass and GPS

Remember: rare earth magnets produce a field that interferes with sensitive sensors. Keep a separation from your phone, device, and navigation systems.

Fire risk

Powder produced during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

This is not a toy

Strictly keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are very dangerous.

Hand protection

Big blocks can smash fingers instantly. Under no circumstances place your hand betwixt two strong magnets.

Operating temperature

Do not exceed the maximum operating temperature stated in the specifications of the particular product. The limit depends on the material, geometry and operating arrangement; there is no single threshold for all neodymium magnets. Overheating can permanently weaken a magnet.

Medical interference

Warning for patients: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.

Powerful field

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.

Protect data

Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.

Protective goggles

NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets leads to them shattering into small pieces.

Avoid contact if allergic

Studies show that nickel (the usual finish) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or choose versions in plastic housing.

Attention! Details about risks in the article: Safety of working with magnets.
