Pulling power drops sharply with every mm of gap. Keep in mind that every additional insulation layer (e.g., contamination, paint, rust) noticeably diminishes the holding power. Neodymiums hold most effectively in perfect adhesion; air break weakens the force. See how rapidly the parameters fall, when the magnet does not adhere directly to the metal substrate. When calculating the assembly, discard unnecessary gaps.

The table below presents the approximate force sufficient to start the shifting of the magnet down on a upright steel wall (assuming standard friction coefficient). This value varies with the distance between the magnet and the surface.

When hanging a holder on a upright wall (e.g., a board), it you can count on only approx. 20%-30% of its maximum pull force. Gravitational force and a weak degree of grip mean that magnets slip easier than they pop off the substrate. Planning a wall mount? Consider that the shear force is much weaker than the maximum static pull force. On a slippery surface, the element will slip down under a noticeably lighter load. Using a rubber coating can drastically increase the grip.

A thin sheet is incapable of take in the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To utilize 100% of this magnet's potential, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the magnet shows lower pull force. We suggest choosing the steel cross-section from these parameters.

Standard neodymium magnets lose parameters after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently damage this product. With every degree above norm, the magnet's capacity momentarily decreases. Avoid using this magnet near heat sources exceeding its operating temperature limit. Exceeding the critical threshold will result in destruction of magnetism.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) are more susceptible to demagnetization under lower heat stress than long magnets. Warning indicator in the table points to permanent field degradation for this particular item.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal combination. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of operation. Planning to create a solid fastener? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is massive. The levitation is slightly lower than the connection force, 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: Calculations refer to shear force of dual same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a large risk to IT equipment as well as medical implants. These magnets generate a field that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (kinetic energy) - collision effects

Neodymium magnets are prone to chipping – a collision with steel risks their cracking. Control the attraction moment – a neodymium left loose turns into a projectile. Impact energy can trigger coating fragments or painful pinches to skin. Be sure to control the product during installation so it doesn't hit violently against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Use safety goggles when playing with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet retains only approx. 20-30% of its nominal pull.

2. Steel saturation

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

3. Temperature resistance

*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) = 1.59

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.

This product is an incredibly powerful cylinder magnet, composed of durable NdFeB material, which, with dimensions of Ø5x30 mm, guarantees maximum efficiency. The MW 5x30 / N38 component is characterized by an accuracy of ±0.1mm and professional build quality, making it an ideal solution for the most demanding engineers and designers. As a cylindrical magnet with impressive force (approx. 0.45 kg), this product is in stock from our European logistics center, ensuring rapid order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.

It finds application in modeling, advanced automation, and broadly understood industry, serving as a positioning or actuating element. Thanks to the high power 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.

Due to the brittleness of the NdFeB material, we absolutely advise against force-fitting (so-called press-fit), as this risks immediate cracking of this professional component. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.

Magnets NdFeB grade N38 are suitable for the majority of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. 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 in continuous sale in our warehouse.

This model is characterized by dimensions Ø5x30 mm, which, at a weight of 4.42 g, makes it an element with impressive magnetic energy density. The key parameter here is the holding force amounting to approximately 0.45 kg (force ~4.40 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against oxidation, giving it an aesthetic, silvery shine.

This rod magnet 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.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Pros

Besides their remarkable pulling force, neodymium magnets offer the following advantages:

They do not lose strength, even during nearly ten years – the decrease in lifting capacity is only ~1% (according to tests),
They possess excellent resistance to magnetism drop when exposed to opposing magnetic fields,
By covering with a reflective coating of gold, the element gains an modern look,
The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
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 versatility in forming and the ability to adapt to specific needs,
Significant place in innovative solutions – they are utilized in HDD drives, electromotive mechanisms, medical devices, also technologically advanced constructions.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their 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
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
Limited ability of creating threads in the magnet and complicated shapes - preferred is a housing - magnetic holder.
Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

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

The specified lifting capacity represents the maximum value, measured under laboratory conditions, specifically:

on a block made of structural steel, optimally conducting the magnetic field
possessing a thickness of at least 10 mm to avoid saturation
with a plane cleaned and smooth
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (in the magnet axis)
at conditions approx. 20°C

Determinants of lifting force in real conditions

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

Distance – the presence of foreign body (rust, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Plate thickness – insufficiently thick plate does not close the flux, causing part of the flux to be lost into the air.
Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Warnings

Magnet fragility

NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets leads to them breaking into shards.

Bodily injuries

Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Be careful!

Do not overheat magnets

Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.

Keep away from computers

Powerful magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.

Conscious usage

Use magnets with awareness. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their force.

Swallowing risk

Product intended for adults. Small elements can be swallowed, leading to serious injuries. Store out of reach of children and animals.

GPS Danger

An intense magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.

Machining danger

Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.

Metal Allergy

It is widely known that nickel (standard magnet coating) is a potent allergen. If you have an allergy, refrain from direct skin contact or select coated magnets.

Pacemakers

Patients with a heart stimulator should maintain an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.

Caution! Learn more about risks in the article: Magnet Safety Guide.
