Magnetic force weakens significantly per each millimeter of gap. Remember that even a microscopic distance (e.g., dirt, varnish, veneer) noticeably reduces the pull force. Magnets hold optimally at the point of direct contact; distance drastically cuts the force. Notice how rapidly the parameters drop, when the magnet does not touch tightly to the steel surface. When planning the assembly, discard additional spacers.

The following data shows the theoretical force sufficient to initiate the shifting of the magnet downwards against a upright steel plate (assuming typical friction coefficient). This parameter is a function of the air gap between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MP 16x8/4x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.83 kg / 1.84 pounds 834.0 g / 8.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.56 kg / 1.23 pounds 556.0 g / 5.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.28 kg / 0.61 pounds 278.0 g / 2.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.39 kg / 3.06 pounds 1390.0 g / 13.6 N

When mounting a holder on a upright plane (e.g., a board), it will only hold only approx. 1/5 of its maximum pull force. Gravity and a low friction coefficient influence the fact that products slide down 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 significantly smaller weight. Utilizing a rubberized layer can significantly increase the grip.

A thin metal plate is not enough to focus the full magnetic flux, which wastes potential of the magnet. Should you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this neodymium's potential, you require a sufficiently solid piece of metal. The material oversaturation means that on delicate walls (e.g., car bodies), the magnet works worse. We suggest choosing the steel cross-section from these parameters.

Ordinary NdFeB products irreversibly lose parameters above the temperature limit. Watch out for overheating – heat can irreversibly damage this magnet. With every degree above norm, the magnet's capacity momentarily decreases. Refrain from using this product near heat sources higher than its operating temperature limit. Too high temperature will cause irreversible degradation of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) are more susceptible to demagnetization sooner than taller cylinders. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnetic products attract each other from a significantly greater distance than a magnet and sheet setup. The setup of magnet-to-magnet produces a massive flux and a larger range of performance. Designing a strong closure? Apply two magnets instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still large.
*The magnetic induction in repulsion mode reaches ~0 Gs in the exact middle of the gap (due to field cancellation).
Attention: Results refer to shear force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a real danger to electronics as well as pacemakers. These magnets produce a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and plastic. Special caution must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can trigger coating fragments or dangerous crushing to skin. Be sure to control the product during bringing near metal so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the magnet. Wear eye protection when working with powerful specimens.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.24

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. This product with a force of 2.78 kg works great as a door latch, speaker holder, or mounting element in devices.

This is a crucial issue when working with model MP 16x8/4x3 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. One turn too many can destroy the magnet, so do it slowly. 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.

Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. 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 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 8/4 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.

This model is characterized by dimensions Ø16x3 mm and a weight of 4.24 g. The key parameter here is the lifting capacity amounting to approximately 2.78 kg (force ~27.29 N). The mounting hole diameter is precisely 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. When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Strengths and weaknesses of rare earth magnets.

Pros

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

They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
They are noted for resistance to demagnetization induced by external field influence,
In other words, due to the metallic surface of nickel, the element looks attractive,
Magnets have impressive magnetic induction on the working surface,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
Thanks to freedom in shaping and the capacity to adapt to client solutions,
Universal use in modern technologies – they serve a role in computer drives, electromotive mechanisms, diagnostic systems, also other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 very resistant to heat
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
We recommend casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex forms.
Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Maximum lifting capacity of the magnet – what it depends on?

The lifting capacity listed is a result of laboratory testing conducted under standard conditions:

using a plate made of low-carbon steel, serving as a ideal flux conductor
with a thickness minimum 10 mm
characterized by lack of roughness
without the slightest air gap between the magnet and steel
under vertical force vector (90-degree angle)
at standard ambient temperature

Determinants of practical lifting force of a magnet

In real-world applications, the real power is determined by several key aspects, listed from crucial:

Gap (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
Base massiveness – insufficiently thick plate does not accept the full field, causing part of the flux to be wasted into the air.
Steel grade – ideal substrate is pure iron steel. Cast iron may attract less.
Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Warnings

Metal Allergy

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop handling magnets and use protective gear.

Fire risk

Powder created during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.

Immense force

Handle magnets with awareness. Their powerful strength can shock even experienced users. Plan your moves and respect their power.

Magnetic media

Avoid bringing magnets close to a wallet, computer, or screen. The magnetic field can destroy these devices and erase data from cards.

Maximum temperature

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.

Bone fractures

Big blocks can break fingers instantly. Never place your hand betwixt two strong magnets.

Medical implants

For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.

GPS Danger

An intense magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Maintain magnets near a device to avoid breaking the sensors.

Beware of splinters

Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets will cause them cracking into small pieces.

Do not give to children

Product intended for adults. Small elements can be swallowed, causing serious injuries. Keep out of reach of children and animals.
