Pulling power drops sharply per each millimeter of gap. Note that even the smallest gap (e.g., dirt, paint, rust) strongly reduces the pull force. Magnets work strongest at the point of direct contact; air break kills the power. See how flashily the pull force drop, when the magnet does not adhere directly to the metal substrate. When designing the mounting, eliminate unnecessary gaps.

This section indicates the theoretical weight limit sufficient to cause the shifting of the magnet down against a upright steel plate (considering standard friction coefficient). The holding force depends on the air gap between the magnet and the surface.

When mounting a magnet on a upright plane (e.g., a board), it will maintain just approx. 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip influence the fact that products slip easier than they pop off the substrate. Want to create a vertical fastening? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the magnet will slip down under a much lighter load. Using a rubber pad can significantly improve the result.

A thin metal plate cannot conduct the full magnetic flux, which weakens actual performance of the holder. Should you mount a strong magnet to a weak sheet, the field will penetrate right through and the pull force will drop sharply. To achieve the maximum of this neodymium's potential, you require a sufficiently solid element of steel. The material oversaturation means that on sheet metal structures (e.g., appliance housings), the magnet holds weaker. We recommend selecting the steel dimension based on the following data.

Classic neodymiums lose power after exceeding the maximum temperature. Watch out for overheating – excessive heat can irreversibly destroy this product. As the temperature rises, the neodymium's capacity temporarily decreases. Avoid using this magnet near heat sources higher than its operating temperature limit. Ignoring the limit will cause irreversible degradation of magnetic properties.

*Important note: Thermal stability is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) are more susceptible to demagnetization under lower heat stress than taller cylinders. Red status in the table indicates permanent field degradation for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and sheet setup. The connection of two magnets generates a stronger field and a larger range of performance. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when bringing together two magnets, the impact force is huge. The repulsion force is marginally weaker than the connection force, but still large.
*Flux density in repulsion mode reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
* Calculations show friction force of dual matching magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a serious hazard to IT equipment and medical implants. These neodymiums generate a flux that disrupts operation of digital equipment. Remember: the invisible magnetic field acts through matter and glass. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely turns into a projectile. Impact energy can trigger coating fragments or injury to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum 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 large magnets.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical wall, the magnet holds merely approx. 20-30% of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly reduces 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 P_c (Permeance Coefficient) = 0.83

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.

MP 5x2.7/1.2x5 S / N38 - ring magnet

0.836 ZŁ brutto / pcs

The ring magnet with a hole MP 5x2.7/1.2x5 S / N38 is created for permanent mounting, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This is a crucial issue when working with model MP 5x2.7/1.2x5 S / 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.

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. If you must use it outside, paint it with anti-corrosion paint after mounting.

A screw or bolt with a thread diameter smaller than 2.7/1.2 mm fits this model. 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. Aesthetic mounting requires selecting the appropriate head size.

It is a magnetic ring with a diameter of 5 mm and thickness 5 mm. The pulling force of this model is an impressive 0.75 kg, which translates to 7.31 N in newtons. The mounting hole diameter is precisely 2.7/1.2 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). When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Strengths and weaknesses of neodymium magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
They possess excellent resistance to weakening of magnetic properties due to external magnetic sources,
By using a decorative layer of gold, the element has an professional look,
Neodymium magnets ensure maximum magnetic induction on a their surface, which increases force concentration,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to the possibility of accurate molding and customization to unique solutions, neodymium magnets can be manufactured in a wide range of shapes and sizes, which makes them more universal,
Key role in modern technologies – they find application in magnetic memories, brushless drives, precision medical tools, and industrial machines.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Cons of neodymium magnets and ways of using them

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
Neodymium magnets decrease their strength 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 recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
We suggest cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these devices can complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Lifting parameters

Maximum holding power of the magnet – what affects it?

The force parameter is a result of laboratory testing performed under specific, ideal conditions:

with the application of a yoke made of special test steel, ensuring maximum field concentration
with a cross-section no less than 10 mm
with a surface free of scratches
with total lack of distance (without impurities)
during pulling in a direction vertical to the mounting surface
at temperature room level

Determinants of practical lifting force of a magnet

In practice, the actual holding force depends on many variables, listed from crucial:

Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Material type – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
Smoothness – ideal contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Safety rules for work with NdFeB magnets

This is not a toy

Absolutely store magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are life-threatening.

Risk of cracking

Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets leads to them shattering into small pieces.

Power loss in heat

Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Pacemakers

Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Safe operation

Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Protect data

Intense magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

GPS Danger

GPS units and mobile phones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.

Skin irritation risks

Certain individuals suffer from a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in dermatitis. We suggest use protective gloves.

Combustion hazard

Powder created during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.

Bodily injuries

Big blocks can break fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.
