Magnetic force decreases significantly with every mm of gap. Keep in mind that every additional insulation layer (e.g., contamination, varnish, veneer) strongly weakens the grip. Neodymiums work optimally at the point of direct contact; gap drastically cuts the power. Analyze how rapidly the parameters drop, when the product does not adhere directly to the steel surface. When designing the mounting, discard unnecessary gaps.

This section defines the theoretical holding capacity necessary to start the sliding of the magnet downwards against a upright metal surface (assuming typical friction). The holding force is a function of the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MP 12x5x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.35 kg / 0.76 lbs 345.0 g / 3.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.23 kg / 0.51 lbs 230.0 g / 2.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.11 kg / 0.25 lbs 115.0 g / 1.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.58 kg / 1.27 lbs 575.0 g / 5.6 N

When hanging a element on a upright plane (e.g., a board), it you can count on only about 1/5 of its nominal power. Gravitational force as well as a weak degree of grip influence the fact that holders slip faster than they pop off the substrate. Designing a hanger? Consider that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the holder will give way down under a noticeably lighter weight. Utilizing a rubberized coating can drastically raise the stability.

Table 4: Material efficiency (saturation) - sheet metal selection
MP 12x5x2 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.11 kg / 0.25 lbs 115.0 g / 1.1 N
1 mm	25%	0.29 kg / 0.63 lbs 287.5 g / 2.8 N
2 mm	50%	0.58 kg / 1.27 lbs 575.0 g / 5.6 N
3 mm	75%	0.86 kg / 1.90 lbs 862.5 g / 8.5 N
5 mm	100%	1.15 kg / 2.54 lbs 1150.0 g / 11.3 N
10 mm	100%	1.15 kg / 2.54 lbs 1150.0 g / 11.3 N
11 mm	100%	1.15 kg / 2.54 lbs 1150.0 g / 11.3 N
12 mm	100%	1.15 kg / 2.54 lbs 1150.0 g / 11.3 N

A too thin steel is not enough to take in the entire magnetic field, which squanders power of the holder. If you mount a strong magnet to a weak sheet, the magnetism will pass right through and the holding will be smaller. To squeeze full efficiency of this magnet's potential, you need a suitably thick piece of metal. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the holder holds weaker. We suggest choosing the steel thickness from these parameters.

Ordinary NdFeB products irreversibly lose power above the temperature limit. Avoid high temperatures – high temperature can permanently damage this product. With increasing heat, the magnet's capacity momentarily lowers. Refrain from using this product close to heaters higher than its operating temperature limit. Too high temperature will cause permanent loss of magnetism.

*Engineering note: Temperature resistance is determined by both grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than taller cylinders. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and sheet setup. The connection of magnet-to-magnet generates a stronger field and a wider radius of action. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a steel. Be careful that when connecting a pair of magnets, the collision energy is extreme. The levitation is a bit weaker than the connection force, but still significant.
*Field value between like poles is approximately ~0 Gs in the exact middle of the gap (due to field cancellation).
Attention: Estimates show shear force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a real danger to electronics as well as pacemakers. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation penetrates the body and housings. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, car keys, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a violent impact against metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or painful pinches to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Wear safety glasses when playing with powerful specimens.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

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 just a fraction of its max power.

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) severely reduces the holding force.

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.34

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.

The ring-shaped magnet MP 12x5x2 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. This product with a force of 1.15 kg works great as a door latch, speaker holder, or spacer element in devices.

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. 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 does not ensure full waterproofing. 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.

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. Always check that the screw head is not larger than the outer diameter of the magnet (12 mm), so it doesn't protrude beyond the outline.

The presented product is a ring magnet with dimensions Ø12 mm (outer diameter) and height 2 mm. The pulling force of this model is an impressive 1.15 kg, which translates to 11.29 N in newtons. The mounting hole diameter is precisely 5 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Strengths

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

They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
Magnets perfectly resist against demagnetization caused by foreign field sources,
In other words, due to the metallic surface of silver, the element is aesthetically pleasing,
Neodymium magnets deliver maximum magnetic induction on a contact point, which increases force concentration,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
In view of the ability of accurate shaping and customization to specialized solutions, neodymium magnets can be manufactured in a wide range of shapes and sizes, which expands the range of possible applications,
Universal use in modern technologies – they are used in magnetic memories, brushless drives, precision medical tools, as well as complex engineering applications.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of NdFeB magnets:

At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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 corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in producing threads and complex forms in magnets, we propose using a housing - magnetic mechanism.
Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Highest magnetic holding force – what affects it?

The specified lifting capacity concerns the limit force, recorded under laboratory conditions, meaning:

using a sheet made of high-permeability steel, serving as a magnetic yoke
whose thickness equals approx. 10 mm
with a plane free of scratches
without the slightest insulating layer between the magnet and steel
during pulling in a direction perpendicular to the plane
at room temperature

Practical lifting capacity: influencing factors

During everyday use, the real power depends on a number of factors, listed from crucial:

Gap (betwixt the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (typically approx. 20-30% of nominal force).
Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be wasted into the air.
Chemical composition of the base – mild steel gives the best results. Higher carbon content reduce magnetic properties and lifting capacity.
Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Temperature influence – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

Safety rules for work with neodymium magnets

Allergic reactions

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, immediately stop handling magnets and use protective gear.

Physical harm

Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!

Operating temperature

Control the heat. Heating the magnet to high heat will destroy its magnetic structure and strength.

Handling rules

Handle magnets consciously. Their powerful strength can shock even experienced users. Stay alert and do not underestimate their force.

Protect data

Powerful magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.

Do not drill into magnets

Powder created during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Do not give to children

Product intended for adults. Tiny parts can be swallowed, leading to severe trauma. Store away from kids and pets.

Medical implants

Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.

Shattering risk

NdFeB magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them cracking into shards.

Threat to navigation

A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets near a smartphone to avoid damaging the sensors.
