Magnetic force drops significantly with every subsequent millimeter of spacing. Remember that every additional insulation layer (e.g., dirt, paint, veneer) significantly diminishes the holding power. Magnets operate optimally at the point of direct contact; air break nullifies the force. Observe how flashily the load capacity drop, when the magnet does not adhere flatly to the steel surface. When calculating the assembly, eliminate unnecessary gaps.

This section indicates the estimated weight limit sufficient to start the shifting of the magnet vertically against a vertical steel plate (considering standard friction coefficient). The holding force varies with the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MW 8x20 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.39 kg / 0.86 pounds 390.0 g / 3.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.26 kg / 0.57 pounds 260.0 g / 2.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.13 kg / 0.29 pounds 130.0 g / 1.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.65 kg / 1.43 pounds 650.0 g / 6.4 N

When mounting a holder on a upright plane (e.g., a car body), it will maintain only approx. 1/5 of its nominal power. Gravity and a low friction coefficient mean that holders move down faster than they pull off. Want to create a vertical fastening? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a significantly smaller cargo. Using a rubber pad can drastically increase the grip.

12 mm	100%	1.30 kg / 2.87 pounds 1300.0 g / 12.8 N

A too thin steel cannot take in the entire magnetic field, which wastes potential of the holder. Should you mount a strong magnet to a thin surface, the flux will pass right through and the pull force will drop sharply. To achieve 100% of this neodymium's power, you need a suitably thick backing of metal. The material oversaturation causes that on thin elements (e.g., appliance housings), the holder holds weaker. We suggest choosing the steel thickness from these parameters.

Ordinary NdFeB products irreversibly lose parameters above the temperature limit. Protect against heat – heat can irreversibly demagnetize this product. As the temperature rises, the magnet's capacity momentarily lowers. Refrain from using this product close to ovens exceeding its operating temperature limit. Too high temperature will lead to permanent loss of magnetism.

*Technical advisory: Thermal stability is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) risk losing magnetic properties at lower temperatures than long magnets. Red status in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. The setup of two magnets creates a more powerful interaction and a further horizon of performance. Designing a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the pinch force is extreme. The levitation is a bit weaker than the connection force, but still impressive.
*Flux density for N-N configuration is approximately ~0 Gs in the exact middle of the gap (due to field cancellation).
* Results refer to shear force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a large risk to electronic devices as well as medical implants. These NdFeB products generate a field that destroys function of sensitive medical devices. Notice: the unseen radiation acts through matter and plastic. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Magnetic elements are delicate – a violent impact against metal causes immediate chipping. Watch the impact speed – a magnet released freely turns into a projectile. Kinetic force can cause material chips or injury to skin. Always hold the magnet during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when playing with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

*Warning: On a vertical surface, the magnet holds only approx. 20-30% of its perpendicular strength.

2. Steel saturation

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

3. Heat tolerance

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.31

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 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.

This product is a very strong rod magnet, composed of durable NdFeB material, which, with dimensions of Ø8x20 mm, guarantees the highest energy density. The MW 8x20 / N38 component boasts an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for professional engineers and designers. As a magnetic rod with significant force (approx. 1.30 kg), this product is in stock from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its Ni-Cu-Ni coating shields it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.

It successfully proves itself in DIY projects, advanced robotics, and broadly understood industry, serving as a fastening or actuating element. Thanks to the high power of 12.71 N with a weight of only 7.54 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using epoxy glues. To ensure long-term durability in industry, 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 industrial neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø8x20), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

The presented product is a neodymium magnet with precisely defined parameters: diameter 8 mm and height 20 mm. The key parameter here is the holding force amounting to approximately 1.30 kg (force ~12.71 N), which, with such compact dimensions, proves the high grade of the NdFeB material. 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 8 mm. Such an arrangement is most desirable 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 Nd₂Fe₁₄B magnets.

Benefits

Apart from their superior magnetism, neodymium magnets have these key benefits:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
They have excellent resistance to magnetism drop due to external fields,
By using a shiny coating of nickel, the element gains an nice look,
Magnetic induction on the working part of the magnet turns out to be impressive,
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 creating and adjusting to concrete applications,
Universal use in high-tech industry – they are used in magnetic memories, electric motors, diagnostic systems, as well as modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Limited ability of creating threads in the magnet and complicated shapes - preferred is cover - magnetic holder.
Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small elements of these products are able to be problematic in diagnostics medical after entering the body.
With mass production the cost of neodymium magnets can be a barrier,

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what contributes to it?

The specified lifting capacity concerns the maximum value, obtained under optimal environment, namely:

on a base made of mild steel, optimally conducting the magnetic flux
whose transverse dimension equals approx. 10 mm
characterized by lack of roughness
under conditions of gap-free contact (metal-to-metal)
under perpendicular force vector (90-degree angle)
in temp. approx. 20°C

Practical aspects of lifting capacity – factors

It is worth knowing that the application force may be lower depending on the following factors, starting with the most relevant:

Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Direction of force – highest force is reached only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
Chemical composition of the base – mild steel gives the best results. Alloy steels lower magnetic permeability and lifting capacity.
Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.

Safe handling of neodymium magnets

Implant safety

Warning for patients: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Flammability

Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.

Product not for children

Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Store out of reach of kids and pets.

Eye protection

Neodymium magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets will cause them breaking into shards.

Phone sensors

Navigation devices and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.

Metal Allergy

Studies show that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands and select coated magnets.

Keep away from computers

Data protection: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).

Maximum temperature

Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. Damage is permanent.

Hand protection

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

Powerful field

Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
