Pulling power drops significantly with every mm of distance. Note that every additional insulation layer (e.g., dirt, varnish, dust) strongly weakens the grip. Magnetic products work strongest in perfect adhesion; distance kills the power. Notice how rapidly the pull force plummet, when the product does not adhere directly to the metal substrate. When calculating the assembly, eliminate redundant distances.

The following data shows the theoretical holding capacity sufficient to cause the sliding of the magnet vertically against a vertical steel plate (assuming standard friction coefficient). The holding force is a function of the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MP 32x16x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.84 kg / 1.85 pounds 837.0 g / 8.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.56 kg / 1.23 pounds 558.0 g / 5.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.28 kg / 0.62 pounds 279.0 g / 2.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.40 kg / 3.08 pounds 1395.0 g / 13.7 N

When hanging a magnet on a vertical plane (e.g., a car body), it will maintain barely approx. 20%-30% of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that holders slip easier than they pop off the substrate. Want to create a wall mount? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the element will slide down under a much lighter cargo. Using a rubber layer can drastically improve the result.

12 mm	100%	2.79 kg / 6.15 pounds 2790.0 g / 27.4 N

A too thin steel is incapable of focus the entire magnetic field, which squanders power of the magnet. Should you attach a powerful product to a too thin substrate, the magnetism will pass right through and the holding will be smaller. To utilize 100% of this neodymium's power, you require a sufficiently solid element of metal. The saturation effect causes that on delicate walls (e.g., car bodies), the magnet works worse. We suggest choosing the steel thickness based on the following data.

Standard neodymium magnets irreversibly lose parameters past the thermal threshold. Avoid high temperatures – excessive heat can permanently destroy this magnet. With increasing heat, the neodymium's capacity temporarily drops. Do not use this magnet in hot environments exceeding its safe range. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) risk losing magnetic properties sooner than long magnets. Red status in the table points to permanent field degradation for this particular item.

Two strong neodymiums interact from a wider radius than a magnet and steel setup. Such a system of two magnets produces a massive flux and a further horizon of operation. Want to build a strong closure? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is massive. The repulsion force is a bit weaker than the connection force, but still significant.
*Field value for N-N configuration drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Attention: Estimates apply to shear force of two same neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a real danger to electronic devices as well as pacemakers. These neodymiums generate a flux that destroys function of sensitive medical devices. Remember: the unseen radiation passes through tissues and housings. Increased vigilance must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

NdFeB products are delicate – a strong collision with metal risks their cracking. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Kinetic force can cause material chips or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when working with large magnets.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Caution: On a vertical surface, the magnet retains merely ~20% of its max power.

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC 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) = 0.90

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-shaped magnet MP 32x16x3 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. 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 32x16x3 / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable and inelastic. When tightening the screw, you must maintain caution. We recommend tightening manually with a screwdriver, not an impact driver, because too much pressure will cause the ring to crack. 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. 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 magnets in hermetic housing or additional protection with varnish.

A screw or bolt with a thread diameter smaller than 16 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. Always check that the screw head is not larger than the outer diameter of the magnet (32 mm), so it doesn't protrude beyond the outline.

The presented product is a ring magnet with dimensions Ø32 mm (outer diameter) and height 3 mm. The pulling force of this model is an impressive 2.79 kg, which translates to 27.40 N in newtons. The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 16 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 Nd₂Fe₁₄B magnets.

Pros

Besides their stability, neodymium magnets are valued for these benefits:

Their magnetic field is maintained, and after around 10 years it decreases only by ~1% (according to research),
They show high resistance to demagnetization induced by presence of other magnetic fields,
By using a decorative coating of silver, the element has an aesthetic look,
They feature high magnetic induction at the operating surface, which affects their effectiveness,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to versatility in designing and the capacity to adapt to client solutions,
Wide application in advanced technology sectors – they are utilized in hard drives, drive modules, precision medical tools, also technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages

Drawbacks and weaknesses of neodymium magnets: weaknesses and usage proposals

At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as 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 stability even at temperatures up to 230°C
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in producing nuts and complicated shapes in magnets, we recommend using a housing - magnetic holder.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small elements of these devices can disrupt the diagnostic process 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

Maximum holding power of the magnet – what it depends on?

The specified lifting capacity concerns the maximum value, measured under optimal environment, namely:

using a plate made of low-carbon steel, serving as a circuit closing element
with a thickness minimum 10 mm
characterized by lack of roughness
without the slightest insulating layer between the magnet and steel
during detachment in a direction perpendicular to the plane
at temperature approx. 20 degrees Celsius

Impact of factors on magnetic holding capacity in practice

Please note that the application force may be lower influenced by the following factors, in order of importance:

Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
Steel type – mild steel attracts best. Alloy steels reduce magnetic properties and holding force.
Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

Safe handling of neodymium magnets

Combustion hazard

Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Bone fractures

Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!

Life threat

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

Handling rules

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Nickel coating and allergies

Studies show that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, refrain from direct skin contact or opt for encased magnets.

Adults only

Adult use only. Tiny parts can be swallowed, causing severe trauma. Store away from kids and pets.

Beware of splinters

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.

Magnetic media

Do not bring magnets near a wallet, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.

Maximum temperature

Do not overheat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Keep away from electronics

An intense magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to avoid breaking the sensors.
