Grip strength weakens significantly with every mm of distance. Keep in mind that even a very thin break (e.g., dirt, paint, veneer) noticeably diminishes the holding power. Magnets work most effectively at the point of direct contact; air break kills the force. Analyze how quickly the parameters fall, when the product does not adhere flatly to the metal substrate. When designing the mounting, discard redundant distances.

The following data shows the approximate force sufficient to initiate the downward movement of the magnet downwards on a vertical steel plate (assuming typical friction coefficient). This parameter varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MP 14x8/4x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.76 kg / 1.67 pounds 759.0 g / 7.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.51 kg / 1.12 pounds 506.0 g / 5.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.25 kg / 0.56 pounds 253.0 g / 2.5 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.27 kg / 2.79 pounds 1265.0 g / 12.4 N

When mounting a holder on a vertical surface (e.g., a car body), it will only hold only approx. 20%-30% of nominal attraction strength. Gravity and a weak degree of grip cause that magnets move down easier than they pop off the substrate. Want to create a wall mount? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the element will slip down under a noticeably lighter cargo. Utilizing a rubberized pad can significantly increase the grip.

A thin metal plate is incapable of focus the entire magnetic field, which squanders power of the magnet. If you install a neodymium to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To utilize the maximum of this neodymium's power, you need a suitably thick element of metal. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel dimension according to the table below.

Ordinary NdFeB products change their properties power above the temperature limit. Watch out for overheating – heat can permanently damage this magnet. As the temperature rises, the magnet's capacity momentarily drops. Refrain from using this magnet close to heaters higher than its safe range. Too high temperature will lead to destruction of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) are more susceptible to demagnetization sooner than long magnets. Red status in the table signals a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a wider radius than a magnet and steel setup. Such a system of two magnets produces a massive flux and a larger range of operation. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is extreme. The repulsion force is slightly lower than the attraction, but still significant.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Figures apply to friction force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to electronics and medical implants. These neodymiums generate a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field acts through matter and housings. Special caution must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

NdFeB products are very brittle – a strong collision with metal can result in shattering. Watch the impact speed – a neodymium left loose speeds with massive force. Kinetic force can destroy the magnet or painful pinches to skin. Be sure to control the product during mounting so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Use safety goggles when working 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!

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Vertical hold

*Caution: On a vertical surface, the magnet retains only ~20% of its perpendicular strength.

2. Plate thickness effect

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.28

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.

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 14x8/4x3 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle 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. 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. In the place of the mounting hole, the coating is thinner and easily scratched when tightening the screw, which will become a corrosion focus. This product is dedicated for inside building 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. 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 Ø14 mm (outer diameter) and height 3 mm. The pulling force of this model is an impressive 2.53 kg, which translates to 24.85 N in newtons. The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 8/4 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. We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Strengths as well as weaknesses of neodymium magnets.

Advantages

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

They do not lose magnetism, even during around ten years – the reduction in strength is only ~1% (according to tests),
Neodymium magnets prove to be exceptionally resistant to demagnetization caused by external interference,
A magnet with a smooth silver surface is more attractive,
The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to freedom in designing and the capacity to adapt to individual projects,
Key role in high-tech industry – they serve a role in HDD drives, electric motors, precision medical tools, as well as modern systems.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions

Limitations

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 extremely resistant to heat
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated forms.
Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can complicate diagnosis medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Magnetic strength at its maximum – what it depends on?

The force parameter is a theoretical maximum value executed under the following configuration:

using a plate made of mild steel, acting as a magnetic yoke
possessing a massiveness of minimum 10 mm to avoid saturation
with a plane perfectly flat
under conditions of no distance (surface-to-surface)
under vertical force direction (90-degree angle)
at ambient temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

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

Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
Temperature – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.

Safety rules for work with neodymium magnets

Pinching danger

Risk of injury: The attraction force is so immense that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.

Respect the power

Use magnets with awareness. Their powerful strength can surprise even professionals. Stay alert and respect their force.

Precision electronics

Remember: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.

Flammability

Powder created during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Health Danger

Patients with a ICD have to keep an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.

No play value

These products are not intended for children. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.

Protect data

Do not bring magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.

Fragile material

Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.

Nickel allergy

Some people have a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Extended handling may cause a rash. We recommend use safety gloves.

Thermal limits

Do not overheat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
