Grip strength drops drastically per each millimeter of distance. Note that even the smallest gap (e.g., contamination, varnish, veneer) significantly diminishes the holding power. Magnetic products work optimally during direct contact; distance drastically cuts the force. Notice how flashily the parameters drop, when the magnet does not adhere tightly to the steel surface. When calculating the arrangement, discard unnecessary gaps.

The table below shows the approximate holding capacity sufficient to start the downward movement of the magnet down on a vertical steel plate (assuming typical friction coefficient). This value is a function of the separation distance between the magnet and the metal.

When hanging a holder on a vertical wall (e.g., a board), it you can count on only about 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip mean that products slip easier than they detach. Planning a hanger? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a noticeably lighter weight. Application of an anti-slip coating can effectively increase the grip.

A too thin steel is incapable of take in the full magnetic flux, which squanders power of the magnet. If you mount a strong magnet to a weak sheet, the flux will penetrate right through and the attraction force will be weaker. To squeeze 100% of this magnet's potential, you need a suitably thick backing of steel. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the product works worse. We advise picking the steel thickness from these parameters.

Ordinary NdFeB products irreversibly lose power after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently destroy this magnet. With increasing heat, the magnet's capacity temporarily decreases. Refrain from using this product in hot environments exceeding its operating temperature limit. Ignoring the limit will cause permanent loss of magnetism.

*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress than taller cylinders. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a much further distance than a neodymium and metal combination. The connection of two magnets generates a stronger field and a wider radius of action. Want to build a strong closure? Use a pair of magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the impact force is extreme. The levitation is a bit weaker than the connection force, but still significant.
*The magnetic induction in repulsion mode drops to ~0 Gs at the geometric center between the magnets (due to field cancellation).
Note: Figures show shear force of two same magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a serious hazard to electronic devices and pacemakers. These NdFeB products generate a flux that disrupts operation of digital equipment. Notice: the unseen radiation penetrates the body and plastic. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

50 mm	31.49 km/h (8.75 m/s)	11.72 J
100 mm	44.16 km/h (12.27 m/s)	23.04 J

NdFeB products are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely becomes dangerous. Impact energy can destroy the magnet or painful pinches to skin. Be sure to control the product during mounting so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the magnet. Use safety goggles when working with large magnets.

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

1. Wall mount (shear)

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

2. Steel thickness impact

*Thin metal sheet (e.g. 0.5mm PC case) severely weakens the holding force.

3. Heat tolerance

*For standard magnets, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.64

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 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.

The ring-shaped magnet MP 62x42x25 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. This product with a force of 58.67 kg works great as a cabinet closure, speaker holder, or mounting element in devices.

This is a crucial issue when working with model MP 62x42x25 / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable and inelastic. One turn too many can destroy the magnet, so do it slowly. The flat screw head should evenly press the magnet. Remember: cracking during assembly results from material properties, not a product defect.

Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. In the place of the mounting hole, the coating is thinner and can be damaged when tightening the screw, which will become a corrosion focus. This product is dedicated for indoor use. For outdoor applications, we recommend choosing rubberized holders or additional protection with varnish.

The inner hole diameter determines the maximum size of the mounting element. If the magnet does not have a chamfer (cone), we recommend using a screw with a flat or cylindrical head, or possibly using a washer. Always check that the screw head is not larger than the outer diameter of the magnet (62 mm), so it doesn't protrude beyond the outline.

The presented product is a ring magnet with dimensions Ø62 mm (outer diameter) and height 25 mm. The key parameter here is the lifting capacity amounting to approximately 58.67 kg (force ~575.60 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 42 mm.

The poles are located on the planes with holes, not on the sides of the ring. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Pros as well as cons of rare earth magnets.

Strengths

Besides their remarkable strength, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
Neodymium magnets are distinguished by exceptionally resistant to loss of magnetic properties caused by external field sources,
In other words, due to the shiny layer of gold, the element looks attractive,
Neodymium magnets achieve maximum magnetic induction on a small area, which increases force concentration,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to modularity in designing and the ability to modify to client solutions,
Wide application in future technologies – they serve a role in computer drives, motor assemblies, medical devices, as well as industrial machines.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Characteristics of disadvantages of neodymium magnets and ways of using them

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 extremely resistant to heat
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
Limited ability of producing nuts in the magnet and complicated shapes - recommended is a housing - magnetic holder.
Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Additionally, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
With large orders the cost of neodymium magnets is economically unviable,

Lifting parameters

Maximum lifting capacity of the magnet – what affects it?

Magnet power is the result of a measurement for optimal configuration, taking into account:

on a plate made of mild steel, effectively closing the magnetic field
possessing a massiveness of minimum 10 mm to ensure full flux closure
with a plane perfectly flat
without the slightest clearance between the magnet and steel
under axial force direction (90-degree angle)
in temp. approx. 20°C

Key elements affecting lifting force

Real force is influenced by specific conditions, such as (from priority):

Gap (between the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of maximum force).
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

Warnings

Operating temperature

Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and strength.

Powerful field

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

Medical implants

For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.

Nickel coating and allergies

A percentage of the population suffer from a hypersensitivity to nickel, which is the common plating for neodymium magnets. Prolonged contact may cause dermatitis. We strongly advise wear safety gloves.

Threat to navigation

An intense magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Maintain magnets close to a device to avoid breaking the sensors.

Risk of cracking

Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.

Electronic hazard

Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.

Physical harm

Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Dust is flammable

Dust generated during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.

Adults only

Adult use only. Small elements pose a choking risk, leading to serious injuries. Keep away from kids and pets.
