Grip strength weakens drastically per each millimeter of gap. Note that every additional insulation layer (e.g., contamination, varnish, rust) noticeably reduces the pull force. Magnets hold most effectively at the point of direct contact; distance weakens the power. See how quickly the pull force plummet, when the product does not touch flatly to the metal substrate. When planning the mounting, discard additional spacers.

This section defines the approximate shear load necessary to initiate the downward movement of the magnet vertically along a vertical steel plate (considering typical friction). The holding force varies with the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MW 15x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.62 kg / 3.56 lbs 1617.0 g / 15.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.08 kg / 2.38 lbs 1078.0 g / 10.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.54 kg / 1.19 lbs 539.0 g / 5.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.70 kg / 5.94 lbs 2695.0 g / 26.4 N

When hanging a element on a vertical plane (e.g., a fridge), it you can count on just about 20%-30% of nominal attraction strength. Gravitational force as well as a low friction coefficient mean that products slide down easier than they pull off. Designing a vertical fastening? Note that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will slip down under a much lighter cargo. Application of an anti-slip layer can drastically increase the grip.

A thin sheet is incapable of take in the entire magnetic field, which squanders power of the magnet. Should you install a neodymium to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To achieve the maximum of this neodymium's potential, you require a sufficiently solid piece of metal. The material oversaturation causes that on thin elements (e.g., car bodies), the magnet works worse. We advise picking the steel thickness according to the table below.

Ordinary NdFeB products change their properties strength above the temperature limit. Avoid high temperatures – heat can permanently damage this magnet. With increasing heat, the neodymium's power temporarily decreases. Do not use this product close to ovens higher than its working range. Too high temperature will cause destruction of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) are more susceptible to demagnetization sooner than taller cylinders. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two magnetic products interact from a significantly greater distance than a magnet and steel setup. The setup of two magnets produces a massive flux and a further horizon of operation. Planning to create a strong closure? Utilize two neodymiums instead of one magnet and a steel. Be careful that when attracting two neodymiums, the collision energy is extreme. The repulsion force is slightly lower than the connection force, but still large.
*Field value between like poles drops to ~0 Gs at the midpoint between the magnets (due to field cancellation).
Note: Calculations apply to shear force of two identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field is a serious hazard to electronic devices as well as medical implants. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Notice: the unseen radiation acts through matter and glass. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Magnetic elements are prone to chipping – a violent impact against metal risks their cracking. Control the attraction moment – a magnet released freely becomes dangerous. Kinetic force can destroy the magnet or injury to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when working with large magnets.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

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

1. Wall mount (shear)

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

2. Steel saturation

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

3. Power loss vs temp

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

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

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

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.

The presented product is an exceptionally strong cylindrical magnet, made from modern NdFeB material, which, with dimensions of Ø15x5 mm, guarantees the highest energy density. The MW 15x5 / N38 component boasts high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a cylindrical magnet with significant force (approx. 5.39 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Additionally, its Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, guaranteeing 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 52.83 N with a weight of only 6.63 g, this cylindrical magnet is indispensable in miniature devices and wherever every gram matters.

Since our magnets have a very precise dimensions, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 15.1 mm) using two-component epoxy glues. To ensure stability in automation, specialized industrial adhesives are used, which are safe for nickel and fill the gap, guaranteeing durability of the connection.

Magnets N38 are suitable for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø15x5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

The presented product is a neodymium magnet with precisely defined parameters: diameter 15 mm and height 5 mm. The value of 52.83 N means that the magnet is capable of holding a weight many times exceeding its own mass of 6.63 g. 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 15 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.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

Their magnetic field is maintained, and after approximately ten years it decreases only by ~1% (according to research),
Neodymium magnets are distinguished by exceptionally resistant to demagnetization caused by external interference,
A magnet with a shiny nickel surface is more attractive,
The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
Thanks to flexibility in designing and the capacity to adapt to specific needs,
Versatile presence in innovative solutions – they are commonly used in computer drives, brushless drives, medical equipment, as well as modern systems.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Cons of neodymium magnets and proposals for their use:

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complicated shapes in magnets, we recommend using cover - magnetic holder.
Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Magnetic strength at its maximum – what affects it?

Breakaway force was determined for the most favorable conditions, including:

on a block made of structural steel, perfectly concentrating the magnetic flux
with a thickness of at least 10 mm
with an ideally smooth contact surface
under conditions of no distance (surface-to-surface)
during detachment in a direction perpendicular to the plane
in neutral thermal conditions

Impact of factors on magnetic holding capacity in practice

It is worth knowing that the working load may be lower subject to the following factors, starting with the most relevant:

Distance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Direction of force – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Plate material – low-carbon steel gives the best results. Higher carbon content reduce magnetic permeability and lifting capacity.
Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was determined by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the load capacity.

H&S for magnets

Respect the power

Handle with care. Neodymium magnets act from a distance and snap with huge force, often quicker than you can react.

Demagnetization risk

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

Magnets are brittle

Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Nickel coating and allergies

Medical facts indicate that nickel (the usual finish) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands and choose versions in plastic housing.

Life threat

Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Protect data

Intense magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Finger safety

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

Swallowing risk

Neodymium magnets are not suitable for play. Accidental ingestion of several magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.

GPS and phone interference

Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.

Flammability

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
