Grip strength drops drastically with every subsequent millimeter of distance. Keep in mind that even a very thin break (e.g., dirt, varnish, veneer) strongly diminishes the holding power. Magnetic products work strongest during direct contact; gap drastically cuts the force. Notice how rapidly the pull force plummet, when the magnet does not adhere directly to the metal substrate. When planning the mounting, eliminate redundant distances.

The following data shows the theoretical weight limit sufficient to initiate the downward movement of the magnet vertically on a upright steel plate (assuming typical friction coefficient). This parameter varies with the gap size between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
MP 22x6x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	4.10 kg / 9.03 LBS 4095.0 g / 40.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.73 kg / 6.02 LBS 2730.0 g / 26.8 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	6.83 kg / 15.05 LBS 6825.0 g / 67.0 N

When placing a magnet on a upright surface (e.g., a fridge), it will only hold barely about 1/5 of its nominal power. Gravitational force as well as a low friction coefficient mean that products slide down faster than they pop off the substrate. Designing a hanger? Remember that the shear force is much weaker than the maximum static pull force. On a slippery surface, the magnet will slip down under a much lighter weight. Application of an anti-slip coating can significantly improve the result.

A thin sheet is unable to absorb the full magnetic flux, which wastes potential of the holder. If you attach a powerful product to a weak sheet, the flux will pass right through and the pull force will drop sharply. To squeeze the maximum of this magnet's power, you require a sufficiently solid piece of metal. The material oversaturation causes that on sheet metal structures (e.g., appliance housings), the magnet holds weaker. We recommend selecting the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly damage this product. As the temperature rises, the magnet's capacity temporarily decreases. Refrain from using this product near heat sources exceeding its working range. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) are more susceptible to demagnetization sooner than long magnets. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a much further distance than a magnet and steel combination. The connection of two magnets produces a massive flux and a further horizon of action. Planning to create a strong closure? Apply two magnets instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the collision energy is huge. The repulsion force is marginally weaker than the attraction, but still significant.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Note: Estimates show friction force of dual matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field is a serious hazard to electronics and medical implants. These magnets generate a flux that disrupts operation of digital equipment. Be aware: the unseen radiation penetrates the body and glass. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a collision with steel can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or injury to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when handling with powerful specimens.

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Vertical hold

*Caution: On a vertical surface, the magnet holds just approx. 20-30% of its max power.

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Thermal stability

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.13

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 22x6x10 / 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 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 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 6 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.

The presented product is a ring magnet with dimensions Ø22 mm (outer diameter) and height 10 mm. The key parameter here is the lifting capacity amounting to approximately 13.65 kg (force ~133.89 N). The mounting hole diameter is precisely 6 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. When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Advantages and disadvantages of neodymium magnets.

Strengths

Besides their tremendous magnetic power, neodymium magnets offer the following advantages:

They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
They show high resistance to demagnetization induced by presence of other magnetic fields,
Thanks to the glossy finish, the coating of nickel, gold-plated, or silver gives an clean appearance,
Magnetic induction on the top side of the magnet is very high,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Possibility of exact machining as well as modifying to specific requirements,
Versatile presence in modern industrial fields – they are used in computer drives, motor assemblies, precision medical tools, also complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems

Cons

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, as well as increases the magnet's durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
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, in case of application outdoors
We suggest cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Pull force analysis

Maximum lifting force for a neodymium magnet – what contributes to it?

The declared magnet strength refers to the peak performance, obtained under ideal test conditions, meaning:

using a base made of high-permeability steel, functioning as a circuit closing element
with a thickness of at least 10 mm
with an ideally smooth contact surface
without the slightest insulating layer between the magnet and steel
for force applied at a right angle (in the magnet axis)
at ambient temperature room level

What influences lifting capacity in practice

In practice, the real power results from many variables, ranked from crucial:

Air gap (betwixt the magnet and the plate), because even a very small distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of nominal force).
Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be lost to the other side.
Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.

Precautions when working with NdFeB magnets

Skin irritation risks

A percentage of the population have a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in an allergic reaction. We recommend use protective gloves.

Fire warning

Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Caution required

Handle magnets with awareness. Their huge power can shock even experienced users. Be vigilant and respect their power.

Implant safety

People with a ICD should keep an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Demagnetization risk

Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.

Swallowing risk

Adult use only. Small elements can be swallowed, causing serious injuries. Store away from children and animals.

Precision electronics

Navigation devices and smartphones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Finger safety

Large magnets can crush fingers in a fraction of a second. Never put your hand betwixt two strong magnets.

Electronic hazard

Equipment safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, medical aids, timepieces).

Risk of cracking

Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
