Pulling power weakens significantly with every mm of gap. Note that even a microscopic distance (e.g., contamination, varnish, veneer) noticeably reduces the pull force. Magnets work strongest in perfect adhesion; air break drastically cuts the power. See how flashily the parameters plummet, when the product does not adhere flatly to the steel surface. When planning the assembly, avoid additional spacers.

The table below indicates the approximate holding capacity necessary to initiate the sliding of the magnet downwards along a upright steel wall (assuming standard friction). This parameter varies with the air gap between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MP 62x42x25 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	17.60 kg / 38.80 lbs 17601.0 g / 172.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	11.73 kg / 25.87 lbs 11734.0 g / 115.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	5.87 kg / 12.93 lbs 5867.0 g / 57.6 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	29.34 kg / 64.67 lbs 29335.0 g / 287.8 N

When hanging a magnet on a vertical surface (e.g., a fridge), it will maintain only approx. 1/5 of its nominal power. Gravitational force and a low friction coefficient mean that magnets slide down easier than they detach. Planning a vertical fastening? Consider that the shear force is significantly lower than the maximum static pull force. On a smooth steel, the element will slip down under a noticeably lighter weight. Using a rubber pad can effectively improve the result.

A thin metal plate is incapable of take in the full magnetic flux, which squanders power of the magnet. Should you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this neodymium's power, you require a sufficiently solid element of steel. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the holder holds weaker. We suggest choosing the steel dimension according to the table below.

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently destroy this product. As the temperature rises, the neodymium's capacity briefly decreases. Do not use this magnet in hot environments exceeding its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) may lose charge permanently under lower heat stress than long magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a significantly greater distance than a neodymium and metal setup. The setup of two magnets generates a stronger field and a wider radius of performance. Designing a powerful holder? Apply two magnets instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the pinch force is massive. The repulsion force is a bit weaker than the attraction, but still large.
*The magnetic induction between like poles reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Estimates apply to sliding force of two identical magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to IT equipment as well as pacemakers. These NdFeB products generate a field that prevents correct functioning of digital equipment. Remember: the unseen radiation penetrates the body and glass. Increased vigilance must be taken by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, remotes, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Dynamics (kinetic energy) - warning

Neodymium magnets are delicate – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely turns into a projectile. Kinetic force can destroy the magnet or injury to fingers. Hold the magnet firmly during installation so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when working with powerful specimens.

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. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

*Note: On a vertical wall, the magnet holds just ~20% of its perpendicular strength.

2. Steel thickness impact

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

3. Thermal stability

*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

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 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 magnet with a hole MP 62x42x25 / N38 is created for permanent mounting, where glue might fail or be insufficient. 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 is a crucial issue when working with model MP 62x42x25 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. When tightening the screw, you must maintain great sensitivity. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force will cause the ring to crack. It's a good idea to use a flexible washer 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 does not ensure full waterproofing. Damage to the protective layer during assembly is the most common cause of rusting. 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. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Aesthetic mounting requires selecting the appropriate head size.

The presented product is a ring magnet with dimensions Ø62 mm (outer diameter) and height 25 mm. The key parameter here is the holding force amounting to approximately 58.67 kg (force ~575.60 N). The mounting hole diameter is precisely 42 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. 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 and cons of neodymium magnets.

Advantages

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

Their magnetic field remains stable, and after approximately ten years it drops only by ~1% (according to research),
Neodymium magnets prove to be exceptionally resistant to demagnetization caused by external interference,
The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
Neodymium magnets generate maximum magnetic induction on a contact point, which ensures high operational effectiveness,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
In view of the possibility of accurate molding and customization to specialized projects, NdFeB magnets can be produced in a broad palette of geometric configurations, which amplifies use scope,
Significant place in future technologies – they find application in hard drives, electric drive systems, medical equipment, and technologically advanced constructions.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

At 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 lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Limited possibility of creating nuts in the magnet and complex forms - preferred is casing - magnet mounting.
Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
Due to expensive raw materials, their price is higher than average,

Holding force characteristics

Maximum holding power of the magnet – what affects it?

The specified lifting capacity refers to the peak performance, obtained under laboratory conditions, meaning:

on a block made of structural steel, perfectly concentrating the magnetic flux
whose thickness equals approx. 10 mm
with a surface cleaned and smooth
without the slightest clearance between the magnet and steel
for force acting at a right angle (pull-off, not shear)
at temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

Real force is affected by working environment parameters, mainly (from most important):

Clearance – existence of foreign body (rust, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Load vector – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
Plate texture – smooth surfaces ensure maximum contact, which increases force. Rough surfaces weaken the grip.
Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was assessed by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.

Safety rules for work with neodymium magnets

Crushing force

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

Nickel allergy

Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness happens, cease handling magnets and wear gloves.

Choking Hazard

Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.

Fire warning

Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Demagnetization risk

Avoid heat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Protect data

Equipment safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).

Magnets are brittle

Neodymium magnets are ceramic materials, meaning they are very brittle. Collision of two magnets will cause them cracking into small pieces.

Handling guide

Handle magnets with awareness. Their huge power can shock even professionals. Plan your moves and do not underestimate their force.

Warning for heart patients

Patients with a ICD have to maintain an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.

Precision electronics

Note: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and navigation systems.
