Grip strength decreases drastically per each millimeter of distance. Remember that even a very thin break (e.g., dirt, paint, rust) significantly diminishes the holding power. Magnets hold optimally in perfect adhesion; gap kills the power. Analyze how quickly the pull force fall, when the magnet does not adhere directly to the steel surface. When planning the mounting, discard unnecessary gaps.

The table below defines the theoretical weight limit sufficient to cause the sliding of the magnet down along a upright metal surface (considering standard friction coefficient). The holding force varies with the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 9x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.58 kg / 1.28 pounds 582.0 g / 5.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.39 kg / 0.86 pounds 388.0 g / 3.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.19 kg / 0.43 pounds 194.0 g / 1.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.97 kg / 2.14 pounds 970.0 g / 9.5 N

When hanging a holder on a vertical surface (e.g., a car body), it will maintain only approx. 20%-30% of its nominal power. Gravity as well as a low friction coefficient influence the fact that products slide down easier than they pop off the substrate. Planning a wall mount? Consider that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will give way down under a noticeably lighter cargo. Using a rubber coating can effectively improve the result.

12 mm	100%	1.94 kg / 4.28 pounds 1940.0 g / 19.0 N

A thin sheet is unable to focus the entire magnetic field, which squanders power of the magnet. Should you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To squeeze the maximum of this neodymium's power, you require a sufficiently solid backing of metal. The material oversaturation means that on delicate walls (e.g., car bodies), the holder works worse. We suggest choosing the steel dimension from these parameters.

Classic neodymiums lose strength above the temperature limit. Avoid high temperatures – heat can permanently damage this product. With increasing heat, the neodymium's power momentarily drops. Do not use this magnet close to heaters higher than its operating temperature limit. Too high temperature will lead to permanent loss of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently under lower heat stress than taller cylinders. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two magnetic products interact from a much further distance than a magnet and steel setup. The connection of two magnets produces a massive flux and a further horizon of performance. Want to build a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still large.
*The magnetic induction in repulsion mode drops to ~0 Gs at the geometric center between the magnets (due to field cancellation).
Attention: Results refer to shear force of a pair of matching magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field is a real danger to electronics and medical implants. These magnets generate a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field acts through matter and glass. Increased vigilance must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - warning

Neodymium magnets are prone to chipping – a strong collision with metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during installation so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when playing with large magnets.

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. Buoyancy helps in lifting finds.

1. Vertical hold

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

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) severely reduces the holding force.

3. Heat tolerance

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.44

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 offered product is an incredibly powerful cylindrical magnet, manufactured from advanced NdFeB material, which, with dimensions of Ø9x3 mm, guarantees optimal power. This specific item boasts high dimensional repeatability and industrial build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with impressive force (approx. 1.94 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Furthermore, its 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 modeling, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power of 18.99 N with a weight of only 1.43 g, this cylindrical magnet is indispensable in electronics and wherever low weight is crucial.

Due to the brittleness of the NdFeB material, you must not use force-fitting (so-called press-fit), as this risks chipping the coating of this precision component. To ensure long-term durability in automation, 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 high resistance to demagnetization. If you need the strongest magnets in the same volume (Ø9x3), 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 9 mm and height 3 mm. The value of 18.99 N means that the magnet is capable of holding a weight many times exceeding its own mass of 1.43 g. The product has a [NiCuNi] coating, which protects the surface against oxidation, giving it an aesthetic, silvery shine.

This cylinder is magnetized axially (along the height of 3 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.

Strengths and weaknesses of neodymium magnets.

Strengths

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

They do not lose power, even during around ten years – the decrease in lifting capacity is only ~1% (theoretically),
They are resistant to demagnetization induced by presence of other magnetic fields,
In other words, due to the glossy layer of silver, the element is aesthetically pleasing,
Neodymium magnets achieve maximum magnetic induction on a contact point, which allows for strong attraction,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
Thanks to flexibility in constructing and the capacity to modify to unusual requirements,
Universal use in future technologies – they are used in computer drives, electric drive systems, precision medical tools, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in small systems

Cons

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited ability of producing threads in the magnet and complicated forms - recommended is a housing - mounting mechanism.
Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these products can be problematic in diagnostics medical when they are in the body.
Due to complex production process, their price is higher than average,

Holding force characteristics

Best holding force of the magnet in ideal parameters – what affects it?

Holding force of 1.94 kg is a measurement result performed under specific, ideal conditions:

using a base made of mild steel, serving as a magnetic yoke
with a thickness minimum 10 mm
characterized by even structure
under conditions of ideal adhesion (metal-to-metal)
during pulling in a direction perpendicular to the plane
in stable room temperature

Lifting capacity in practice – influencing factors

During everyday use, the actual holding force is determined by a number of factors, listed from most significant:

Distance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Direction of force – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
Material composition – different alloys reacts the same. High carbon content worsen the attraction effect.
Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Warnings

Warning for heart patients

For implant holders: Powerful magnets affect medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

Crushing risk

Big blocks can smash fingers in a fraction of a second. Never place your hand between two strong magnets.

Keep away from computers

Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.

Operating temperature

Do not overheat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Nickel coating and allergies

Studies show that nickel (the usual finish) is a potent allergen. If you have an allergy, refrain from touching magnets with bare hands and select versions in plastic housing.

Flammability

Powder produced during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Do not give to children

Neodymium magnets are not intended for children. Swallowing several magnets can lead to them attracting across intestines, which poses a critical condition and necessitates immediate surgery.

Compass and GPS

Note: neodymium magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, tablet, and GPS.

Protective goggles

Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.

Powerful field

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
