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. Sliding resistance

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

2. Efficiency vs thickness

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

3. Power loss vs temp

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) = 0.29

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 products

The presented product is an exceptionally strong rod magnet, composed of durable NdFeB material, which, with dimensions of Ø10x2 mm, guarantees the highest energy density. The MW 10x2 zestaw 50 szt. / N38 model features an accuracy of ±0.1mm and industrial build quality, making it a perfect solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 1.27 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Moreover, 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 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 59 g, this rod is indispensable in miniature devices and wherever low weight is crucial.
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, specialized industrial adhesives are used, which are safe for nickel 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 10 mm and height 2 mm. The value of 12.50 N means that the magnet is capable of holding a weight many times exceeding its own mass of 59 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.
This rod magnet is magnetized axially (along the height of 2 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.

Advantages and disadvantages of neodymium magnets.

Benefits

Apart from their notable power, neodymium magnets have these key benefits:
  • They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
  • Magnets perfectly defend themselves against demagnetization caused by external fields,
  • A magnet with a metallic gold surface has better aesthetics,
  • They are known for high magnetic induction at the operating surface, which improves attraction properties,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
  • Possibility of accurate forming as well as modifying to precise requirements,
  • Key role in future technologies – they are used in data components, electric motors, medical equipment, as well as other advanced devices.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons

Characteristics of disadvantages of neodymium magnets and ways of using them
  • They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
  • Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Due to limitations in creating nuts and complicated forms in magnets, we propose using cover - magnetic holder.
  • Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these devices can be problematic in diagnostics medical after entering the body.
  • Due to neodymium price, their price is relatively high,

Holding force characteristics

Maximum holding power of the magnet – what contributes to it?

The declared magnet strength refers to the maximum value, recorded under ideal test conditions, meaning:
  • on a block made of structural steel, perfectly concentrating the magnetic field
  • with a cross-section no less than 10 mm
  • with a surface perfectly flat
  • under conditions of gap-free contact (metal-to-metal)
  • during detachment in a direction perpendicular to the mounting surface
  • in stable room temperature

What influences lifting capacity in practice

Holding efficiency is affected by working environment parameters, such as (from priority):
  • Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
  • Steel thickness – too thin plate does not close the flux, causing part of the power to be escaped into the air.
  • Material type – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
  • Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
  • Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet 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 lifting capacity.

Warnings
Threat to navigation

A powerful magnetic field disrupts the operation of compasses in phones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.

Keep away from children

NdFeB magnets are not intended for children. Swallowing several magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.

Electronic devices

Avoid bringing magnets near a wallet, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.

Shattering risk

NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.

Skin irritation risks

A percentage of the population suffer from a hypersensitivity to Ni, which is the common plating for neodymium magnets. Extended handling may cause dermatitis. It is best to use safety gloves.

Fire risk

Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Maximum 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.

ICD Warning

Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Respect the power

Exercise caution. Neodymium magnets attract from a distance and snap with massive power, often faster than you can move away.

Bone fractures

Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
