Pulling power drops drastically with every subsequent millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, varnish, veneer) strongly reduces the pull force. Neodymiums work optimally in perfect adhesion; distance kills the power. See how quickly the parameters drop, when the product does not touch flatly to the metal substrate. When planning the assembly, discard redundant distances.

The table below defines the estimated shear load needed to initiate the sliding of the magnet down against a vertical metal surface (considering standard friction coefficient). This value varies with the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 5x30 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.14 kg / 0.30 LBS 135.0 g / 1.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.09 kg / 0.20 LBS 90.0 g / 0.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.10 LBS 45.0 g / 0.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.23 kg / 0.50 LBS 225.0 g / 2.2 N

When mounting a element on a vertical plane (e.g., a car body), it will maintain just about 20%-30% of its nominal power. Gravity and a weak degree of grip mean that magnets slip faster than they detach. Designing a hanger? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a much lighter load. Using a rubber layer can drastically improve the result.

A thin metal plate is unable to absorb the entire magnetic field, which wastes potential of the magnet. Should you attach a powerful product to a weak sheet, the magnetism will pass right through and the pull force will drop sharply. To utilize full efficiency of this magnet's potential, you need a suitably thick element of steel. The saturation effect means that on thin elements (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel cross-section according to the table below.

Standard neodymium magnets irreversibly lose parameters after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently demagnetize this product. With every degree above norm, the neodymium's power temporarily decreases. Avoid using this magnet close to ovens exceeding its safe range. Too high temperature will lead to destruction of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) risk losing magnetic properties sooner compared to rod magnets. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a neodymium and metal combination. Such a system of magnet-to-magnet produces a massive flux and a larger range of performance. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is extreme. The levitation is slightly lower than the attraction, but still impressive.
*Field value in repulsion mode drops to ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Attention: Figures refer to friction force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a serious hazard to IT equipment as well as pacemakers. These neodymiums produce a flux that disrupts operation of digital equipment. Be aware: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can cause material chips or injury to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the metal. A collision at high speed means shattering of the magnet. Wear eye protection when handling with large magnets.

1. Sliding resistance

*Caution: On a vertical surface, the magnet holds just ~20% of its max power.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly weakens the holding force.

3. Temperature resistance

*For N38 grade, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.59

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.

The presented product is a very strong cylindrical magnet, made from modern NdFeB material, which, at dimensions of Ø5x30 mm, guarantees optimal power. This specific item features high dimensional repeatability and professional build quality, making it an ideal solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.45 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast 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 automation, and broadly understood industry, serving as a fastening or actuating element. Thanks to the pull force of 4.40 N with a weight of only 4.42 g, this cylindrical magnet 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., 5.1 mm) using two-component epoxy glues. To ensure stability 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 professional neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø5x30), 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 Ø5x30 mm, which, at a weight of 4.42 g, makes it an element with high magnetic energy density. The key parameter here is the holding force amounting to approximately 0.45 kg (force ~4.40 N), which, with such defined dimensions, proves the high power of the NdFeB material. The product has a [NiCuNi] coating, which protects the surface against external factors, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 30 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 through the diameter if your project requires it.

Pros and cons of neodymium magnets.

Strengths

Besides their tremendous field intensity, neodymium magnets offer the following advantages:

They do not lose power, even over around 10 years – the decrease in lifting capacity is only ~1% (based on measurements),
They are extremely resistant to demagnetization induced by external field influence,
By applying a smooth coating of nickel, the element presents an proper look,
Magnets exhibit impressive magnetic induction on the outer side,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of detailed forming and optimizing to concrete conditions,
Versatile presence in innovative solutions – they are utilized in HDD drives, electric motors, medical devices, also industrial machines.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in producing nuts and complicated shapes in magnets, we recommend using casing - magnetic holder.
Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum magnetic pulling force – what it depends on?

Information about lifting capacity is the result of a measurement for the most favorable conditions, taking into account:

using a base made of mild steel, serving as a magnetic yoke
with a cross-section minimum 10 mm
with an ideally smooth touching surface
without the slightest insulating layer between the magnet and steel
during pulling in a direction perpendicular to the mounting surface
at ambient temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

It is worth knowing that the application force may be lower subject to the following factors, in order of importance:

Gap between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
Material type – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal weaken the grip.
Thermal factor – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.

Safety rules for work with neodymium magnets

Do not overheat magnets

Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.

Bodily injuries

Big blocks can crush fingers instantly. Under no circumstances place your hand between two strong magnets.

Data carriers

Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.

Skin irritation risks

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease handling magnets and use protective gear.

GPS and phone interference

An intense magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to prevent breaking the sensors.

Pacemakers

Patients with a ICD must maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the implant.

Caution required

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.

Swallowing risk

Adult use only. Small elements pose a choking risk, leading to severe trauma. Store away from children and animals.

Fire risk

Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Material brittleness

NdFeB magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets leads to them shattering into shards.
