Grip strength decreases significantly with every mm of spacing. Note that even a microscopic distance (e.g., dirt, paint, rust) strongly weakens the grip. Magnetic products hold strongest during direct contact; air break nullifies the power. Analyze how quickly the pull force plummet, when the product does not touch tightly to the steel surface. When calculating the assembly, avoid unnecessary gaps.

The table below defines the approximate shear load needed to initiate the shifting of the magnet down against a vertical metal surface (assuming typical friction coefficient). This parameter is a function of the gap size between the magnet and the metal.

When mounting a element on a vertical surface (e.g., a board), it you can count on just about 20%-30% of its nominal power. Gravitational force as well as a low friction coefficient mean that products slip easier than they pull off. Planning a wall mount? Note that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will give way down under a much lighter cargo. Utilizing a rubberized coating can significantly increase the grip.

A thin sheet cannot absorb the entire magnetic field, which weakens actual performance of the magnet. If you install a neodymium to a thin surface, the field will pass right through and the holding will be smaller. To achieve the maximum of this neodymium's power, you need a suitably thick piece of steel. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the product works worse. We suggest choosing the steel thickness based on the following data.

Ordinary NdFeB products lose parameters above the temperature limit. Avoid high temperatures – high temperature can irreversibly damage this product. With increasing heat, the neodymium's capacity temporarily decreases. Refrain from using this product in hot environments higher than its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.
*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) may lose charge permanently at lower temperatures compared to rod magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a magnet and steel setup. The setup of two magnets generates a stronger field and a further horizon of operation. Planning to create a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the impact force is huge. The levitation is slightly lower than the connection force, but still significant.
*Field value between like poles reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Important: Results refer to sliding force of two same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a large risk to IT equipment as well as pacemakers. These neodymiums produce a flux that disrupts operation of sensitive medical devices. Notice: the unseen radiation penetrates the body and plastic. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

NdFeB products are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a neodymium left loose becomes dangerous. Impact energy can destroy the magnet or injury to skin. Hold the magnet firmly during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Use safety goggles when handling with large magnets.

1. Shear force

*Warning: On a vertical surface, the magnet retains only ~20% of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) severely reduces the holding force.

3. Power loss vs temp

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.74

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 Pc (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 Pc 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 extremely powerful rod magnet, composed of durable NdFeB material, which, with dimensions of Ø14x10 mm, guarantees maximum efficiency. This specific item is characterized by an accuracy of ±0.1mm and industrial build quality, making it an excellent solution for the most demanding engineers and designers. As a magnetic rod with significant force (approx. 6.71 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring quick order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating effectively protects it against corrosion in standard operating conditions, ensuring an aesthetic appearance and durability for years.
This model is perfect for building electric motors, advanced sensors, and efficient magnetic separators, where maximum induction on a small surface counts. Thanks to the pull force of 65.83 N with a weight of only 11.55 g, this rod is indispensable in electronics and wherever low weight is crucial.
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 do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Magnets N38 are strong enough for 90% of applications in modeling and machine building, where extreme miniaturization with maximum force is not required. If you need the strongest magnets in the same volume (Ø14x10), 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 Ø14x10 mm, which, at a weight of 11.55 g, makes it an element with impressive magnetic energy density. The value of 65.83 N means that the magnet is capable of holding a weight many times exceeding its own mass of 11.55 g. The product has a [NiCuNi] coating, which protects the surface 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 14 mm. 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.

Pros as well as cons of neodymium magnets.

Pros

Besides their high retention, neodymium magnets are valued for these benefits:
  • They do not lose power, even after around ten years – the drop in strength is only ~1% (according to tests),
  • They are resistant to demagnetization induced by external magnetic fields,
  • Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
  • They feature high magnetic induction at the operating surface, which affects their effectiveness,
  • Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
  • Possibility of custom forming and optimizing to specific applications,
  • Key role in electronics industry – they are commonly used in mass storage devices, brushless drives, advanced medical instruments, also industrial machines.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in compact constructions

Weaknesses

What to avoid - cons of neodymium magnets and ways of using them
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing nuts and complicated shapes in magnets, we recommend using cover - magnetic holder.
  • Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can 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 can limit application in large quantities

Pull force analysis

Maximum lifting force for a neodymium magnet – what it depends on?

Magnet power was determined for the most favorable conditions, including:
  • using a sheet made of low-carbon steel, serving as a circuit closing element
  • with a thickness no less than 10 mm
  • with a plane free of scratches
  • without any clearance between the magnet and steel
  • during detachment in a direction vertical to the plane
  • at temperature room level

Magnet lifting force in use – key factors

During everyday use, the real power results from several key aspects, presented from the most important:
  • Distance (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
  • Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
  • Steel thickness – too thin sheet does not accept the full field, causing part of the power to be wasted to the other side.
  • Chemical composition of the base – mild steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
  • Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
  • Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.

H&S for magnets
Skin irritation risks

It is widely known that nickel (the usual finish) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and choose versions in plastic housing.

Thermal limits

Watch the temperature. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.

Danger to the youngest

Only for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from kids and pets.

Material brittleness

NdFeB magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets will cause them cracking into shards.

Magnetic media
