Pulling power decreases sharply with every subsequent millimeter of gap. Keep in mind that even a microscopic distance (e.g., contamination, varnish, rust) noticeably diminishes the holding power. Magnetic products work strongest at the point of direct contact; air break nullifies the power. Analyze how flashily the parameters plummet, when the product does not adhere tightly to the steel surface. When calculating the mounting, avoid additional spacers.

The following data presents the theoretical weight limit necessary to cause the downward movement of the magnet down on a upright steel plate (assuming typical friction). The holding force is a function of the separation distance between the magnet and the surface.

When hanging a magnet on a upright wall (e.g., a fridge), it will maintain only about 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip influence the fact that holders slip easier than they detach. Want to create a vertical fastening? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the element will slide down under a noticeably lighter load. Using a rubber coating can significantly improve the result.

A too thin steel is not enough to conduct the entire magnetic field, which wastes potential of the magnet. Should you attach a powerful product to a thin surface, the field will pass right through and the pull force will drop sharply. To squeeze full efficiency of this magnet's potential, you need a suitably thick backing of metal. The saturation effect means that on delicate walls (e.g., appliance housings), the holder works worse. We recommend selecting the steel thickness according to the table below.

Ordinary NdFeB products irreversibly lose parameters after exceeding the maximum temperature. Avoid high temperatures – heat can irreversibly demagnetize this magnet. With increasing heat, the neodymium's power temporarily lowers. Avoid using this magnet close to ovens higher than its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetic properties.
*Important note: Heat tolerance is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Warning indicator in the table signals a risk of irreversible loss for this particular item.

Two magnets interact from a wider radius than a magnet and sheet combination. The setup of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Planning to create a solid fastener? Apply two magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the collision energy is massive. The levitation is marginally weaker than the connection force, but still large.
*Flux density for N-N configuration drops to ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
* Results apply to shear force of dual same magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field poses a real danger to electronic devices and medical implants. These NdFeB products produce a field that destroys function of digital equipment. Remember: the invisible magnetic field passes through tissues and plastic. Special caution must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

NdFeB products are very brittle – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during bringing near metal so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when handling with powerful specimens.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

*Caution: On a vertical surface, the magnet holds only a fraction of its max power.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) severely limits the holding force.

3. Power loss vs temp

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.13

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 offered product is an incredibly powerful cylindrical magnet, produced from advanced NdFeB material, which, at dimensions of Ø18x1.5 mm, guarantees the highest energy density. The MW 18x1.5 / N38 model features high dimensional repeatability and professional build quality, making it a perfect solution for professional engineers and designers. As a cylindrical magnet with significant force (approx. 0.95 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its triple-layer Ni-Cu-Ni coating shields it against corrosion in typical operating conditions, guaranteeing an aesthetic appearance and durability for years.
This model is ideal for building generators, advanced Hall effect sensors, and efficient filters, where field concentration on a small surface counts. Thanks to the pull force of 9.34 N with a weight of only 2.86 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., 18.1 mm) using two-component epoxy glues. To ensure stability in automation, specialized industrial adhesives are used, which do not react with the nickel coating and fill the gap, guaranteeing durability of the connection.
Magnets NdFeB grade N38 are strong enough for 90% 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 (Ø18x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
The presented product is a neodymium magnet with precisely defined parameters: diameter 18 mm and height 1.5 mm. The key parameter here is the holding force amounting to approximately 0.95 kg (force ~9.34 N), which, with such compact dimensions, proves the high grade of the NdFeB material. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.
This cylinder is magnetized axially (along the height of 1.5 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.

Pros as well as cons of neodymium magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:
  • Their strength is durable, and after approximately 10 years it drops only by ~1% (according to research),
  • Magnets effectively resist against loss of magnetization caused by foreign field sources,
  • In other words, due to the glossy layer of silver, the element becomes visually attractive,
  • Magnetic induction on the top side of the magnet is very high,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • In view of the option of free molding and adaptation to individualized solutions, neodymium magnets can be created in a variety of forms and dimensions, which increases their versatility,
  • Wide application in innovative solutions – they serve a role in computer drives, electric drive systems, diagnostic systems, and technologically advanced constructions.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:
  • At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
  • We warn that neodymium magnets can reduce their power 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 advise using waterproof magnets e.g. in rubber, plastic
  • Limited ability of making nuts in the magnet and complex shapes - preferred is a housing - magnetic holder.
  • Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, small components of these products can be problematic in diagnostics medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Magnetic strength at its maximum – what contributes to it?

Magnet power was defined for ideal contact conditions, taking into account:
  • on a base made of mild steel, perfectly concentrating the magnetic flux
  • with a cross-section no less than 10 mm
  • characterized by smoothness
  • with zero gap (without coatings)
  • under vertical application of breakaway force (90-degree angle)
  • in temp. approx. 20°C

Lifting capacity in practice – influencing factors

During everyday use, the actual holding force depends on a number of factors, listed from crucial:
  • Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
  • Angle of force application – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
  • Base massiveness – too thin steel causes magnetic saturation, causing part of the power to be lost to the other side.
  • Chemical composition of the base – mild steel gives the best results. Alloy admixtures decrease magnetic permeability and lifting capacity.
  • Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
  • Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Warnings
Keep away from computers

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

Mechanical processing

Dust produced during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Respect the power

Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their force.

Crushing force

Protect your hands. Two large magnets will join immediately with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Impact on smartphones

A strong magnetic field negatively affects the functioning of compasses in phones and navigation systems. Maintain magnets near a device to prevent breaking the sensors.

Heat warning

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

Danger to pacemakers

Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Avoid contact if allergic

Certain individuals suffer from a sensitization to Ni, which is the typical protective layer for neodymium magnets. Frequent touching might lead to dermatitis. We recommend use protective gloves.

Eye protection

NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets leads to them shattering into small pieces.

No play value

Strictly store magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are tragic.
