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.

Magnetic force drops significantly with every subsequent millimeter of distance. Note that even a very thin break (e.g., dirt, varnish, veneer) noticeably diminishes the holding power. Neodymiums operate strongest in perfect adhesion; distance kills the force. Analyze how rapidly the load capacity plummet, when the product does not adhere tightly to the steel surface. When designing the arrangement, discard unnecessary gaps.

Table 2: Slippage force (vertical surface)

The table below presents the approximate force needed to start the shifting of the magnet down on a upright steel wall (assuming standard friction). This value varies with the air gap between the magnet and the metal.

Table 3: Wall mounting (shearing) - vertical pull
MW 8x2 / N38

Surface type	Friction coefficient / %	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% of nominal force	0.22 kg / 0.49 pounds 223.8 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% of nominal force	0.15 kg / 0.33 pounds 149.2 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% of nominal force	0.07 kg / 0.16 pounds 74.6 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% of nominal force	0.37 kg / 0.82 pounds 373.1 g / 3.7 N

When hanging a element on a upright surface (e.g., a board), it you can count on just approx. 1/5 of its nominal power. Gravity and a low friction coefficient influence the fact that magnets slip easier than they detach. Designing a vertical fastening? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the holder will give way down under a significantly smaller weight. Using a rubber coating can drastically increase the grip.

Table 4: Steel thickness (substrate influence) - power losses
MW 8x2 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.07 kg / 0.16 pounds 74.6 g / 0.7 N
1 mm	25%	0.19 kg / 0.41 pounds 186.5 g / 1.8 N
2 mm	50%	0.37 kg / 0.82 pounds 373.1 g / 3.7 N
3 mm	75%	0.56 kg / 1.23 pounds 559.6 g / 5.5 N
5 mm	100%	0.75 kg / 1.64 pounds 746.1 g / 7.3 N
10 mm	100%	0.75 kg / 1.64 pounds 746.1 g / 7.3 N
11 mm	100%	0.75 kg / 1.64 pounds 746.1 g / 7.3 N
12 mm	100%	0.75 kg / 1.64 pounds 746.1 g / 7.3 N

A thin metal plate is incapable of conduct the entire magnetic field, which weakens actual performance of the holder. Should you attach a powerful product to a weak sheet, the flux will pass right through and the pull force will drop sharply. To utilize 100% of this magnet's power, you need a suitably thick backing of metal. The saturation effect means that on sheet metal structures (e.g., thin profiles), the holder holds weaker. We recommend selecting the steel dimension according to the table below.

Table 5: Thermal resistance (stability) - power drop
MW 8x2 / N38

Magnet temperature (°C)	Force change relative to 20°C	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	0.75 kg / 1.64 pounds 746.1 g / 7.3 N	Estimate
40 °C	-4.4%	0.71 kg / 1.57 pounds 713.7 g / 7.0 N	Estimate
60 °C	-8.6%	0.68 kg / 1.50 pounds 681.9 g / 6.7 N	Estimate
80 °C	-12.8%	0.65 kg / 1.43 pounds 650.9 g / 6.4 N	Material limit
100 °C	—	—	Out of range — no model

The table estimates the reversible force change relative to 20°C, assuming a Br coefficient of -0.11%/°C and force proportional to Br². This is a simplified model with unchanged contact and geometry, not a measurement. Above the material limit, neither force nor irreversible magnetization loss is predicted.

The temperature limit comes from this product’s material data. Permissible conditions also depend on geometry and the magnetic circuit. Without B-H curves for the specific grade and temperature, Pc alone does not determine irreversible demagnetization. Values within the material range do not guarantee the allowable temperature of the complete assembly.

Two magnets attract each other from a much further distance than a magnet and sheet combination. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of performance. Want to build a powerful holder? Use a pair of magnets instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the impact force is extreme. The levitation is a bit weaker than the attraction, but still impressive.
*Flux density in repulsion mode is approximately ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
* Results refer to sliding force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Do not use this table to assess the safety of a pacemaker, defibrillator or other implant; follow the device manufacturer’s and your clinician’s guidance. Steel and other magnets change the field distribution.

Magnetic elements are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when playing with large magnets.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

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

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) significantly limits the holding force.

3. Thermal stability

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 P_c (Permeance Coefficient) = 0.35

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 P_c (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 P_c 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 rod magnet, produced from modern NdFeB material, which, with dimensions of Ø8x2 mm, guarantees optimal power. The MW 8x2 / N38 component boasts a tolerance of ±0.1mm and professional build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 0.00 kg), this product is available off-the-shelf from our European logistics center, ensuring rapid order fulfillment. Moreover, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

This model is ideal for building generators, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the high power of 0.00 N with a weight of only 0 g, this rod is indispensable in electronics 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., 8.1 mm) using two-component 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 high repeatability 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 8 mm and height 2 mm. The value of 0.00 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0 g. The product has a [NiCuNi] coating, which secures it against oxidation, 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 8 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 through the diameter if your project requires it.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Pros

Besides their stability, neodymium magnets are valued for these benefits:

Their strength is maintained, and after around ten years it drops only by ~1% (theoretically),
Magnets perfectly resist against loss of magnetization caused by external fields,
By using a decorative layer of gold, the element gains an nice look,
Neodymium magnets achieve maximum magnetic induction on a small surface, which allows for strong attraction,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of custom forming as well as optimizing to precise needs,
Significant place in advanced technology sectors – they are used in magnetic memories, electromotive mechanisms, diagnostic systems, also other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Cons

Drawbacks and weaknesses of neodymium magnets: tips and applications.

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in producing nuts and complex forms in magnets, we propose using a housing - magnetic mechanism.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price exceeds standard values,

Lifting parameters

Detachment force of the magnet in optimal conditions – what affects it?

The specified lifting capacity concerns the maximum value, recorded under ideal test conditions, specifically:

using a plate made of low-carbon steel, acting as a ideal flux conductor
possessing a thickness of min. 10 mm to avoid saturation
characterized by lack of roughness
with total lack of distance (no paint)
for force acting at a right angle (in the magnet axis)
at conditions approx. 20°C

Determinants of lifting force in real conditions

Please note that the application force may be lower subject to elements below, starting with the most relevant:

Clearance – existence of any layer (paint, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Load vector – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
Steel thickness – too thin steel does not close the flux, causing part of the power to be escaped to the other side.
Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet and the plate decreases the holding force.

H&S for magnets

Do not drill into magnets

Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.

GPS and phone interference

Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Powerful field

Exercise caution. Rare earth magnets act from a distance and connect with huge force, often quicker than you can react.

Medical interference

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.

Crushing force

Big blocks can break fingers instantly. Never put your hand between two strong magnets.

Choking Hazard

Absolutely store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.

Electronic devices

Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and erase data from cards.

Material brittleness

NdFeB magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets will cause them cracking into shards.

Demagnetization risk

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.

Allergy Warning

Studies show that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, avoid direct skin contact and opt for versions in plastic housing.
