Grip strength decreases sharply with every subsequent millimeter of gap. Keep in mind that every additional insulation layer (e.g., dirt, varnish, dust) noticeably reduces the pull force. Magnets operate most effectively at the point of direct contact; gap nullifies the force. Analyze how flashily the pull force drop, when the magnet does not adhere flatly to the steel surface. When calculating the mounting, eliminate redundant distances.

This section indicates the theoretical force necessary to start the shifting of the magnet downwards on a vertical steel wall (assuming typical friction coefficient). The holding force depends on the separation distance between the magnet and the metal.

When hanging a holder on a upright wall (e.g., a fridge), it you can count on barely approx. 1/5 of its nominal power. Gravity as well as a weak degree of grip mean that products move down faster than they pull off. Designing a hanger? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a noticeably lighter weight. Using a rubber pad can drastically raise the stability.

A thin sheet cannot conduct the full magnetic flux, which weakens actual performance of the magnet. Should you attach a powerful product to a weak sheet, the field will pass right through and the attraction force will be weaker. To utilize the maximum of this magnet's potential, you need a suitably thick element of metal. The saturation effect means that on sheet metal structures (e.g., appliance housings), the product holds weaker. We recommend selecting the steel dimension from these parameters.

Ordinary NdFeB products lose strength past the thermal threshold. Protect against heat – excessive heat can permanently damage this magnet. With every degree above norm, the magnet's capacity briefly drops. Refrain from using this magnet close to heaters exceeding its working range. Ignoring the limit will lead to destruction of magnetic properties.
*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) are more susceptible to demagnetization under lower heat stress than taller cylinders. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a neodymium and metal combination. Such a system of two magnets produces a massive flux and a further horizon of action. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the collision energy is huge. The repulsion force is slightly lower than the connection force, but still large.
*The magnetic induction between like poles is approximately ~0 Gs at the geometric center of the gap (due to field cancellation).
* Calculations show friction force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a real danger to electronics and pacemakers. These NdFeB products generate a field that disrupts operation of sensitive medical devices. Notice: the unseen radiation passes through tissues and plastic. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose speeds with massive force. Kinetic force can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains only a fraction of its max power.

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely weakens 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 Pc (Permeance Coefficient) = 0.76

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.

This product is an extremely powerful cylindrical magnet, composed of modern NdFeB material, which, with dimensions of Ø40x30 mm, guarantees maximum efficiency. This specific item boasts high dimensional repeatability and industrial build quality, making it a perfect solution for the most demanding engineers and designers. As a magnetic rod with impressive force (approx. 54.73 kg), this product is available off-the-shelf from our warehouse in Poland, ensuring lightning-fast order fulfillment. Moreover, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
It finds application in DIY projects, advanced robotics, and broadly understood industry, serving as a positioning or actuating element. Thanks to the pull force of 536.88 N with a weight of only 282.74 g, this rod is indispensable in electronics and wherever every gram matters.
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 professional component. To ensure long-term durability 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.
Grade N38 is the most popular standard for professional neodymium magnets, offering an optimal price-to-power ratio and operational stability. If you need the strongest magnets in the same volume (Ø40x30), 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 Ø40x30 mm, which, at a weight of 282.74 g, makes it an element with high magnetic energy density. The value of 536.88 N means that the magnet is capable of holding a weight many times exceeding its own mass of 282.74 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 40 mm. Such an arrangement is standard 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.

Pros and cons of Nd2Fe14B magnets.

Advantages

Besides their high retention, neodymium magnets are valued for these benefits:
  • They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
  • They feature excellent resistance to magnetism drop when exposed to external fields,
  • A magnet with a smooth silver surface looks better,
  • Magnets have excellent magnetic induction on the working surface,
  • Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
  • Thanks to versatility in constructing and the ability to customize to complex applications,
  • Wide application in advanced technology sectors – they find application in hard drives, electric motors, medical equipment, and industrial machines.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of neodymium magnets:
  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
  • Due to limitations in producing threads and complex forms in magnets, we recommend using casing - magnetic mount.
  • Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
  • With budget limitations the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

The lifting capacity listed is a theoretical maximum value conducted under the following configuration:
  • using a plate made of low-carbon steel, functioning as a ideal flux conductor
  • possessing a massiveness of minimum 10 mm to ensure full flux closure
  • with a plane cleaned and smooth
  • under conditions of ideal adhesion (surface-to-surface)
  • during pulling in a direction vertical to the plane
  • at room temperature

Determinants of practical lifting force of a magnet

It is worth knowing that the application force may be lower influenced by elements below, starting with the most relevant:
  • Distance – existence of any layer (rust, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
  • Plate thickness – too thin steel does not close the flux, causing part of the power to be escaped to the other side.
  • Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
  • Surface finish – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
  • Thermal factor – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. In addition, even a small distance between the magnet and the plate reduces the load capacity.

Safe handling of neodymium magnets
Warning for heart patients

Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Threat to navigation

Note: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your phone, tablet, and navigation systems.

Do not underestimate power

Handle magnets with awareness. Their immense force can shock even experienced users. Stay alert and respect their force.

Magnets are brittle

Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Do not overheat magnets

Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.

Electronic hazard

Device Safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, timepieces).

Warning for allergy sufferers

Medical facts indicate that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent direct skin contact or choose encased magnets.

Pinching danger

Danger of trauma: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Danger to the youngest

Adult use only. Tiny parts can be swallowed, causing severe trauma. Store away from kids and pets.

Combustion hazard

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