Pulling power weakens drastically with every subsequent millimeter of distance. Note that every additional insulation layer (e.g., dirt, paint, dust) strongly diminishes the holding power. Magnetic products hold strongest during direct contact; air break kills the force. Observe how rapidly the pull force drop, when the product does not adhere flatly to the steel surface. When planning the assembly, discard additional spacers.

This section calculates the theoretical force required to initiate the sliding of the magnet downwards against a vertical steel wall (assuming typical friction coefficient). The holding force is relative to the gap size between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MP 20x8x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.17 kg / 4.78 pounds 2166.0 g / 21.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.44 kg / 3.18 pounds 1444.0 g / 14.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.72 kg / 1.59 pounds 722.0 g / 7.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.61 kg / 7.96 pounds 3610.0 g / 35.4 N

When placing a magnet on a vertical surface (e.g., a car body), it will maintain just approx. 20%-30% of its nominal power. Gravity and a low friction coefficient influence the fact that holders slip faster than they detach. Want to create a vertical fastening? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a much lighter cargo. Utilizing a rubberized coating can drastically increase the grip.

A too thin steel is not enough to take in the full magnetic flux, which wastes potential of the holder. Should you attach a powerful product to a weak sheet, the flux will pass right through and the attraction force will be weaker. To squeeze 100% of this neodymium's power, you require a sufficiently solid element of metal. The material oversaturation means that on sheet metal structures (e.g., thin profiles), the magnet holds weaker. We advise picking the steel thickness based on the following data.

Ordinary NdFeB products change their properties power above the temperature limit. Avoid high temperatures – high temperature can irreversibly destroy this product. With increasing heat, the neodymium's capacity temporarily lowers. Avoid using this product close to heaters higher than its safe range. Ignoring the limit will cause permanent loss of magnetism.

*Technical advisory: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization sooner compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a significantly greater distance than a neodymium and metal combination. The connection of magnet-to-magnet produces a massive flux and a further horizon of action. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is huge. The repulsion force is marginally weaker than the attraction, but still significant.
*Flux density between like poles is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Calculations show sliding force of two identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Protective zones (implants) - precautionary measures
MP 20x8x6 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	14.5 cm
Hearing aid	10 Gs (1.0 mT)	11.5 cm

Extremely neodym field is a real danger to electronic devices and pacemakers. These neodymiums produce a flux that disrupts operation of digital equipment. Notice: the unseen radiation acts through matter and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are prone to chipping – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or injury to skin. Always hold the magnet during installation so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the magnet. Wear eye protection when playing with large magnets.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

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

1. Shear force

*Note: On a vertical wall, the magnet retains just a fraction of its nominal pull.

2. Plate thickness effect

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

3. Temperature resistance

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.14

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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. 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 20x8x6 / 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. 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 8 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 (20 mm), so it doesn't protrude beyond the outline.

It is a magnetic ring with a diameter of 20 mm and thickness 6 mm. The pulling force of this model is an impressive 7.22 kg, which translates to 70.81 N in newtons. The mounting hole diameter is precisely 8 mm.

The poles are located on the planes with holes, not on the sides of the ring. 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.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Pros

Apart from their notable power, neodymium magnets have these key benefits:

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
They retain their magnetic properties even under external field action,
In other words, due to the smooth layer of nickel, the element becomes visually attractive,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
Due to the potential of precise shaping and adaptation to individualized requirements, neodymium magnets can be manufactured in a variety of shapes and sizes, which expands the range of possible applications,
Fundamental importance in modern technologies – they are used in HDD drives, electric drive systems, advanced medical instruments, and multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in miniature devices

Limitations

Cons of neodymium magnets and ways of using them

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited ability of making threads in the magnet and complicated forms - recommended is a housing - magnet mounting.
Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these products can disrupt the diagnostic process medical when they are in the body.
With mass production the cost of neodymium magnets can be a barrier,

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what affects it?

Holding force of 7.22 kg is a measurement result executed under standard conditions:

with the contact of a sheet made of low-carbon steel, guaranteeing maximum field concentration
whose thickness reaches at least 10 mm
with an ground contact surface
under conditions of no distance (metal-to-metal)
during pulling in a direction vertical to the mounting surface
in temp. approx. 20°C

Lifting capacity in real conditions – factors

During everyday use, the actual lifting capacity depends on a number of factors, presented from crucial:

Gap (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
Thermal environment – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.

Safe handling of neodymium magnets

Nickel coating and allergies

Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and wear gloves.

Conscious usage

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.

Bodily injuries

Danger of trauma: The pulling power is so great that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.

Magnet fragility

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Cards and drives

Equipment safety: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).

GPS Danger

GPS units and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Fire risk

Machining of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Adults only

NdFeB magnets are not suitable for play. Swallowing a few magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires urgent medical intervention.

Do not overheat magnets

Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.

Medical implants

Patients with a heart stimulator should keep an safe separation from magnets. The magnetic field can interfere with the operation of the life-saving device.
