Magnetic force drops drastically with every subsequent millimeter of distance. Keep in mind that even a very thin break (e.g., contamination, paint, dust) noticeably reduces the pull force. Magnetic products operate strongest in perfect adhesion; distance weakens the force. Notice how quickly the pull force plummet, when the magnet does not adhere tightly to the metal substrate. When planning the arrangement, avoid unnecessary gaps.

The following data defines the approximate force required to initiate the downward movement of the magnet down on a vertical metal surface (assuming standard friction). This value depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MW 4x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.15 kg / 0.34 LBS 153.0 g / 1.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.10 kg / 0.22 LBS 102.0 g / 1.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.05 kg / 0.11 LBS 51.0 g / 0.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.26 kg / 0.56 LBS 255.0 g / 2.5 N

When hanging a element on a upright wall (e.g., a fridge), it you can count on barely about 20%-30% of nominal attraction strength. Gravitational force as well as a low friction coefficient cause that magnets slip faster than they detach. Want to create a hanger? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the holder will slide down under a noticeably lighter cargo. Using a rubber pad can significantly increase the grip.

12 mm	100%	0.51 kg / 1.12 LBS 510.0 g / 5.0 N

A thin metal plate is not enough to absorb the entire magnetic field, which weakens actual performance of the magnet. Should you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this magnet's power, you need a suitably thick backing of steel. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel thickness based on the following data.

Ordinary NdFeB products lose power past the thermal threshold. Watch out for overheating – excessive heat can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's power momentarily drops. Do not use this product close to ovens exceeding its operating temperature limit. Too high temperature will lead to irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) risk losing magnetic properties sooner than long magnets. Red status in the table signals permanent field degradation for this specific geometry.

Two magnets interact from a much further distance than a magnet and steel setup. The connection of two magnets generates a stronger field and a larger range of performance. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a steel. Remember that when attracting two neodymiums, the impact force is huge. The repulsion force is marginally weaker than the connection force, but still large.
*Flux density for N-N configuration is approximately ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
* Figures apply to friction force of two matching magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to electronic devices and pacemakers. These NdFeB products generate a field that disrupts operation of sensitive medical devices. Notice: the unseen radiation acts through matter and glass. Special caution must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - warning
MW 4x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	36.95 km/h (10.26 m/s)	0.02 J
30 mm	63.99 km/h (17.78 m/s)	0.06 J
50 mm	82.62 km/h (22.95 m/s)	0.10 J
100 mm	116.84 km/h (32.45 m/s)	0.20 J

Neodymium magnets are very brittle – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely becomes dangerous. Striking energy can cause material chips or painful pinches to skin. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when working with powerful specimens.

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

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Sliding resistance

*Note: On a vertical wall, the magnet retains only a fraction of its max power.

2. Steel thickness impact

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.89

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 an exceptionally strong cylindrical magnet, manufactured from modern NdFeB material, which, with dimensions of Ø4x4 mm, guarantees the highest energy density. This specific item boasts high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.51 kg), this product is available off-the-shelf from our European logistics center, ensuring lightning-fast 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 created for building generators, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 4.96 N with a weight of only 0.38 g, this rod is indispensable in miniature devices and wherever every gram matters.

Due to the delicate structure of the ceramic sinter, you must not use force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. 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.

Grade N38 is the most popular standard for industrial neodymium magnets, offering a great economic balance and operational stability. If you need even stronger magnets in the same volume (Ø4x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.

This model is characterized by dimensions Ø4x4 mm, which, at a weight of 0.38 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 0.51 kg (force ~4.96 N), which, with such compact dimensions, proves the high power of the NdFeB material. 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 4 mm. Such an arrangement is standard 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.

Strengths and weaknesses of neodymium magnets.

Strengths

In addition to their pulling strength, neodymium magnets provide the following advantages:

They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
They are resistant to demagnetization induced by presence of other magnetic fields,
Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
Magnetic induction on the working layer of the magnet remains exceptional,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of individual shaping and adjusting to specific needs,
Fundamental importance in electronics industry – they are used in HDD drives, electric drive systems, advanced medical instruments, and multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Disadvantages

What to avoid - cons of neodymium magnets and ways of using them

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
Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
Limited possibility of making threads in the magnet and complex shapes - preferred is casing - magnet mounting.
Possible danger resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child safety. Additionally, small elements of these magnets can disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting force for a neodymium magnet – what affects it?

Magnet power was determined for ideal contact conditions, including:

with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
with a thickness minimum 10 mm
with a surface cleaned and smooth
under conditions of ideal adhesion (surface-to-surface)
for force applied at a right angle (pull-off, not shear)
at ambient temperature room level

Practical lifting capacity: influencing factors

Effective lifting capacity impacted by working environment parameters, such as (from priority):

Air gap (betwixt the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
Steel type – mild steel gives the best results. Higher carbon content reduce magnetic properties and lifting capacity.
Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate decreases the holding force.

Warnings

Caution required

Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.

Skin irritation risks

A percentage of the population suffer from a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to a rash. We recommend wear safety gloves.

Threat to navigation

Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.

Do not overheat magnets

Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.

Dust explosion hazard

Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Medical interference

For implant holders: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.

Keep away from children

Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Keep out of reach of kids and pets.

Crushing force

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

Eye protection

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Electronic hazard

Avoid bringing magnets near a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
