Magnetic force weakens sharply with every mm of spacing. Keep in mind that even the smallest gap (e.g., dirt, varnish, rust) strongly diminishes the holding power. Magnetic products work strongest at the point of direct contact; distance weakens the power. Notice how flashily the load capacity drop, when the product does not adhere flatly to the metal substrate. When calculating the arrangement, eliminate redundant distances.

The following data shows the estimated weight limit sufficient to initiate the slippage of the magnet downwards along a upright steel wall (considering typical friction). This value is a function of the gap size between the magnet and the metal.

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.89 kg / 1.95 lbs 886.0 g / 8.7 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.22 kg / 4.88 lbs 2215.0 g / 21.7 N

When hanging a holder on a vertical plane (e.g., a car body), it will maintain just about 20%-30% of its maximum pull force. Gravity and a low friction coefficient cause that holders slip faster than they detach. Designing a hanger? Remember that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the magnet will slide down under a much lighter cargo. Utilizing a rubberized layer can effectively increase the grip.

A thin sheet is unable to focus the full magnetic flux, which squanders power of the holder. If you attach a powerful product to a thin surface, the flux will pass right through and the pull force will drop sharply. To squeeze the maximum of this magnet's power, you need a suitably thick backing of metal. The material oversaturation causes that on delicate walls (e.g., appliance housings), the product holds weaker. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose power after exceeding the maximum temperature. Protect against heat – high temperature can permanently damage this product. With every degree above norm, the neodymium's force momentarily drops. Avoid using this magnet close to heaters higher than its operating temperature limit. Ignoring the limit will lead to permanent loss of magnetism.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a much further distance than a magnet and sheet setup. The setup of magnet-to-magnet produces a massive flux and a wider radius of performance. Want to build a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Remember that when connecting a pair of magnets, the collision energy is extreme. The levitation is a bit weaker than the connection force, but still impressive.
*Flux density between like poles drops to ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Important: Calculations refer to friction force of dual matching magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a large risk to electronics and medical implants. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and glass. Special caution must be taken by people with cochlear implants and insulin pumps. The risk also applies to: mechanical watches, car keys, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Impact energy (cracking risk) - collision effects
MW 16x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	27.98 km/h (7.77 m/s)	0.18 J
30 mm	47.35 km/h (13.15 m/s)	0.52 J
50 mm	61.12 km/h (16.98 m/s)	0.87 J
100 mm	86.44 km/h (24.01 m/s)	1.74 J

Neodymium magnets are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when working with powerful specimens.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Warning: On a vertical wall, the magnet retains merely approx. 20-30% of its perpendicular strength.

2. Steel saturation

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

3. Thermal stability

*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) = 0.35

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 rod magnet, composed of modern NdFeB material, which, with dimensions of Ø16x4 mm, guarantees the highest energy density. This specific item is characterized by a tolerance of ±0.1mm and professional build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 4.43 kg), this product is in stock from our warehouse in Poland, ensuring rapid order fulfillment. Additionally, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.

This model is created for building electric motors, advanced sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the high power of 43.46 N with a weight of only 6.03 g, this rod is indispensable in miniature devices and wherever low weight is crucial.

Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 16.1 mm) using two-component epoxy glues. To ensure stability 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.

Magnets NdFeB grade N38 are strong enough for the majority of applications in automation and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø16x4), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard available off-the-shelf in our warehouse.

This model is characterized by dimensions Ø16x4 mm, which, at a weight of 6.03 g, makes it an element with high magnetic energy density. The value of 43.46 N means that the magnet is capable of holding a weight many times exceeding its own mass of 6.03 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 16 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 diametrically if your project requires it.

Pros as well as cons of rare earth magnets.

Strengths

Apart from their consistent power, neodymium magnets have these key benefits:

They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
They possess excellent resistance to magnetism drop as a result of external fields,
In other words, due to the smooth finish of nickel, the element looks attractive,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
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...
Thanks to the possibility of flexible molding and adaptation to individualized solutions, magnetic components can be modeled in a variety of geometric configurations, which increases their versatility,
Key role in modern industrial fields – they find application in mass storage devices, electromotive mechanisms, precision medical tools, also technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Weaknesses

Disadvantages of neodymium magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Due to limitations in realizing nuts and complex shapes in magnets, we recommend using casing - magnetic holder.
Health risk to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to be problematic in diagnostics medical when they are in the body.
With large orders the cost of neodymium magnets is a challenge,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what contributes to it?

Information about lifting capacity is the result of a measurement for ideal contact conditions, including:

using a sheet made of mild steel, functioning as a circuit closing element
possessing a thickness of minimum 10 mm to ensure full flux closure
with an polished touching surface
with total lack of distance (without impurities)
during detachment in a direction vertical to the plane
at conditions approx. 20°C

Lifting capacity in real conditions – factors

Holding efficiency is affected by working environment parameters, mainly (from priority):

Clearance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Angle of force application – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
Surface finish – full contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
Temperature – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate lowers the load capacity.

Safety rules for work with NdFeB magnets

Danger to the youngest

Strictly store magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.

Demagnetization risk

Control the heat. Heating the magnet to high heat will ruin its magnetic structure and strength.

Electronic hazard

Do not bring magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and erase data from cards.

Allergic reactions

Certain individuals suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching may cause an allergic reaction. We strongly advise use protective gloves.

Magnetic interference

A powerful magnetic field negatively affects the operation of compasses in phones and navigation systems. Do not bring magnets near a smartphone to avoid damaging the sensors.

Dust is flammable

Powder produced during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Bone fractures

Pinching hazard: The pulling power is so great that it can cause hematomas, pinching, and broken bones. Use thick gloves.

Caution required

Use magnets consciously. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their power.

Beware of splinters

NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them breaking into shards.

Health Danger

Patients with a pacemaker must maintain an safe separation from magnets. The magnetism can disrupt the functioning of the implant.
