Magnetic force drops significantly with every subsequent millimeter of gap. Note that even a microscopic distance (e.g., dirt, varnish, veneer) strongly weakens the grip. Magnets operate most effectively at the point of direct contact; distance drastically cuts the power. Analyze how flashily the parameters drop, when the magnet does not adhere directly to the metal substrate. When planning the mounting, discard redundant distances.

This section defines the approximate holding capacity needed to initiate the sliding of the magnet downwards on a upright steel wall (assuming typical friction). The holding force is relative to the gap size between the magnet and the surface.

When hanging a holder on a vertical plane (e.g., a car body), it will only hold barely about 1/5 of its nominal power. Gravity as well as a weak degree of grip cause that holders slip faster than they pop off the substrate. Planning a hanger? Remember that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the element will give way down under a noticeably lighter weight. Utilizing a rubberized coating can drastically raise the stability.

A thin sheet is incapable of absorb the entire magnetic field, which weakens actual performance of the magnet. If you mount a strong magnet to a too thin substrate, the flux will pass right through and the holding will be smaller. To achieve 100% of this magnet's power, you need a suitably thick piece of steel. The saturation phenomenon means that on delicate walls (e.g., appliance housings), the product holds weaker. We advise picking the steel cross-section from these parameters.

Standard neodymium magnets irreversibly lose strength past the thermal threshold. Protect against heat – high temperature can permanently damage this product. As the temperature rises, the magnet's power momentarily drops. Do not use this magnet near heat sources higher than its operating temperature limit. Too high temperature will result in permanent loss of magnetic properties.
*Technical advisory: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) risk losing magnetic properties sooner compared to rod magnets. Red status in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a wider radius than a magnet and sheet setup. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of action. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the impact force is massive. The levitation is a bit weaker than the connection force, but still large.
*The magnetic induction between like poles is approximately ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Calculations show friction force of two matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field poses a serious hazard to electronic devices as well as pacemakers. These neodymiums generate a field that disrupts operation of sensitive medical devices. Remember: the unseen radiation penetrates the body and housings. Exceptional care must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, remotes, speakers, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Impact energy can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when working with powerful specimens.

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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

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

2. Steel saturation

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

3. Thermal stability

*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) = 0.26

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Thanks to the hole (often for a screw), this model enables quick installation to wood, wall, plastic, or metal. It is also often used in advertising for fixing signs and in workshops for organizing tools.
This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. One turn too many can destroy the magnet, so do it slowly. It's a good idea to use a rubber spacer under the screw head, which will cushion the stresses. Remember: cracking during assembly results from material properties, not a product defect.
These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but is not sufficient for rain. Damage to the protective layer during assembly is the most common cause of rusting. This product is dedicated for inside building use. For outdoor applications, we recommend choosing magnets in hermetic housing or additional protection with varnish.
The inner hole diameter determines the maximum size of the mounting element. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Always check that the screw head is not larger than the outer diameter of the magnet (15 mm), so it doesn't protrude beyond the outline.
The presented product is a ring magnet with dimensions Ø15 mm (outer diameter) and height 3 mm. The pulling force of this model is an impressive 2.71 kg, which translates to 26.61 N in newtons. The mounting hole diameter is precisely 7/3.5 mm.
These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. In the case of connecting two rings, make sure one is turned the right way. We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Advantages as well as disadvantages of rare earth magnets.

Strengths

Apart from their strong magnetic energy, neodymium magnets have these key benefits:
  • They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
  • They show high resistance to demagnetization induced by external field influence,
  • By applying a shiny coating of silver, the element acquires an aesthetic look,
  • They show high magnetic induction at the operating surface, which affects their effectiveness,
  • 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 modularity in designing and the capacity to adapt to unusual requirements,
  • Key role in future technologies – they are used in data components, brushless drives, advanced medical instruments, as well as industrial machines.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of NdFeB magnets:
  • At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
  • Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 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 immune to moisture, in case of application outdoors
  • Limited possibility of producing nuts in the magnet and complex shapes - preferred is a housing - magnet mounting.
  • Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
  • With mass production the cost of neodymium magnets is economically unviable,

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

The load parameter shown refers to the limit force, obtained under optimal environment, namely:
  • on a plate made of structural steel, optimally conducting the magnetic flux
  • possessing a massiveness of minimum 10 mm to avoid saturation
  • characterized by lack of roughness
  • under conditions of ideal adhesion (metal-to-metal)
  • during detachment in a direction vertical to the plane
  • in neutral thermal conditions

Determinants of practical lifting force of a magnet

Real force impacted by specific conditions, mainly (from priority):
  • Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Angle of force application – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
  • Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
  • Plate texture – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
  • Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

H&S for magnets
Nickel allergy

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.

Cards and drives

Very strong magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.

Fragile material

Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Hand protection

Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!

Safe operation

Handle magnets with awareness. Their powerful strength can shock even professionals. Be vigilant and respect their power.

Heat sensitivity

Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. This process is irreversible.

Danger to the youngest

Strictly keep magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are tragic.

GPS and phone interference

A powerful magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Do not bring magnets close to a device to prevent breaking the sensors.

Dust explosion hazard

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

Medical implants

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