Pulling power decreases drastically with every subsequent millimeter of distance. Remember that even a microscopic distance (e.g., contamination, varnish, dust) strongly reduces the pull force. Neodymiums operate optimally in perfect adhesion; gap kills the force. Notice how quickly the pull force fall, when the product does not touch tightly to the metal substrate. When designing the arrangement, eliminate unnecessary gaps.

The table below defines the estimated holding capacity necessary to initiate the slippage of the magnet downwards on a vertical metal surface (considering standard friction). This parameter varies with the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MP 5x2.7/1.2x5 C / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.22 kg / 0.50 LBS 225.0 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 LBS 150.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 LBS 75.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.38 kg / 0.83 LBS 375.0 g / 3.7 N

When hanging a holder on a vertical surface (e.g., a car body), it you can count on only about 1/5 of its maximum pull force. Gravity as well as a low friction coefficient influence the fact that magnets move down faster than they pull off. Want to create a wall mount? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a noticeably lighter load. Utilizing a rubberized coating can drastically raise the stability.

A too thin steel cannot conduct the entire magnetic field, which wastes potential of the magnet. If you attach a powerful product to a too thin substrate, the field will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this magnet's potential, you need a suitably thick piece of steel. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the magnet holds weaker. We advise picking the steel thickness from these parameters.

Classic neodymiums lose strength above the temperature limit. Watch out for overheating – excessive heat can permanently destroy this product. With increasing heat, the magnet's force briefly decreases. Do not use this magnet close to ovens exceeding its safe range. Too high temperature will result in irreversible degradation of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Flat magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures than long magnets. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a significantly greater distance than a magnet and steel combination. The connection of two magnets generates a stronger field and a larger range of operation. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a steel. Remember that when attracting two neodymiums, the collision energy is huge. The levitation is a bit weaker than the connection force, but still significant.
*Flux density for N-N configuration reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
* Results demonstrate shear force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a large risk to electronic devices as well as medical implants. These neodymiums produce a field that destroys function of sensitive medical devices. Notice: the unseen radiation passes through tissues and glass. Special caution must be taken by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Impact energy can cause material chips or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with powerful specimens.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds only a fraction of its perpendicular strength.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) severely reduces the holding force.

3. Heat tolerance

*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) = 0.83

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.

8.59 ZŁ brutto / pcs

The ring magnet with a hole MP 5x2.7/1.2x5 C / N38 is created for permanent mounting, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. This product with a force of 0.75 kg works great as a cabinet closure, speaker holder, or spacer element in devices.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. 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. If you must use it outside, paint it with anti-corrosion paint after mounting.

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 Ø5 mm (outer diameter) and height 5 mm. The pulling force of this model is an impressive 0.75 kg, which translates to 7.31 N in newtons. The mounting hole diameter is precisely 2.7/1.2 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.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Benefits

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

They retain magnetic properties for almost 10 years – the drop is just ~1% (based on simulations),
They possess excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
In other words, due to the reflective surface of gold, the element is aesthetically pleasing,
Magnetic induction on the working layer of the magnet is maximum,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
Thanks to modularity in shaping and the capacity to customize to complex applications,
Universal use in modern technologies – they find application in magnetic memories, motor assemblies, diagnostic systems, and other advanced devices.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Weaknesses

Drawbacks and weaknesses of neodymium magnets and ways of using them

To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. 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
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Limited possibility of creating nuts in the magnet and complicated shapes - recommended is cover - mounting mechanism.
Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Holding force characteristics

Maximum holding power of the magnet – what affects it?

The specified lifting capacity represents the peak performance, obtained under ideal test conditions, specifically:

with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
possessing a massiveness of minimum 10 mm to avoid saturation
with an ground contact surface
without any clearance between the magnet and steel
for force acting at a right angle (in the magnet axis)
in neutral thermal conditions

What influences lifting capacity in practice

It is worth knowing that the magnet holding will differ subject to elements below, starting with the most relevant:

Distance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
Plate thickness – too thin plate does not close the flux, causing part of the power to be escaped into the air.
Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.

H&S for magnets

Magnet fragility

Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.

Warning for heart patients

Warning for patients: Powerful magnets affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.

Power loss in heat

Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Conscious usage

Handle magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and respect their power.

Do not give to children

Strictly keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are fatal.

Electronic devices

Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).

Phone sensors

GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Finger safety

Protect your hands. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Avoid contact if allergic

Studies show that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands and select coated magnets.

Fire warning

Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
