Engineering simulation of the magnet - data

The following data constitute the outcome of a physical calculation. Values were calculated on algorithms for the material Nd₂Fe₁₄B. Real-world conditions might slightly deviate from the simulation results. Treat these calculations as a reference point for designers.

Table 1: Static force (force vs distance) - power drop
MP 5x1.5x3 / N38

Distance (mm)	Induction (Gauss) / mT	Pull Force (kg/lbs/g/N)	Risk Status
0 mm	6157 Gs 615.7 mT	0.77 kg / 1.70 lbs 770.0 g / 7.6 N	weak grip

5 mm	641 Gs 64.1 mT	0.01 kg / 0.02 lbs 8.3 g / 0.1 N	weak grip
10 mm	174 Gs 17.4 mT	0.00 kg / 0.00 lbs 0.6 g / 0.0 N	weak grip
15 mm	76 Gs 7.6 mT	0.00 kg / 0.00 lbs 0.1 g / 0.0 N	weak grip
20 mm	41 Gs 4.1 mT	0.00 kg / 0.00 lbs 0.0 g / 0.0 N	weak grip
30 mm	16 Gs 1.6 mT	0.00 kg / 0.00 lbs 0.0 g / 0.0 N	weak grip
50 mm	5 Gs 0.5 mT	0.00 kg / 0.00 lbs 0.0 g / 0.0 N	weak grip

Magnetic force drops significantly with every subsequent millimeter of distance. Keep in mind that even the smallest gap (e.g., contamination, varnish, rust) significantly weakens the grip. Magnetic products operate strongest in perfect adhesion; gap kills the force. See how flashily the load capacity fall, when the magnet does not touch tightly to the metal substrate. When calculating the assembly, eliminate unnecessary gaps.

This section calculates the approximate weight limit required to start the sliding of the magnet vertically on a upright metal surface (assuming standard friction coefficient). The holding force varies with the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MP 5x1.5x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.23 kg / 0.51 lbs 231.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.34 lbs 154.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 lbs 77.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.39 kg / 0.85 lbs 385.0 g / 3.8 N

When hanging a holder on a vertical plane (e.g., a fridge), it will only hold barely about 1/5 of nominal attraction strength. Gravity and a weak degree of grip cause that products slip easier than they pull off. Designing a wall mount? Remember that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the holder will slide down under a noticeably lighter cargo. Application of an anti-slip layer can significantly increase the grip.

Table 4: Steel thickness (substrate influence) - sheet metal selection
MP 5x1.5x3 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.08 kg / 0.17 lbs 77.0 g / 0.8 N
1 mm	25%	0.19 kg / 0.42 lbs 192.5 g / 1.9 N
2 mm	50%	0.39 kg / 0.85 lbs 385.0 g / 3.8 N
3 mm	75%	0.58 kg / 1.27 lbs 577.5 g / 5.7 N
5 mm	100%	0.77 kg / 1.70 lbs 770.0 g / 7.6 N
10 mm	100%	0.77 kg / 1.70 lbs 770.0 g / 7.6 N
11 mm	100%	0.77 kg / 1.70 lbs 770.0 g / 7.6 N
12 mm	100%	0.77 kg / 1.70 lbs 770.0 g / 7.6 N

A thin sheet is incapable of conduct the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To achieve the maximum of this magnet's potential, you need a suitably thick backing of steel. The material oversaturation causes that on sheet metal structures (e.g., thin profiles), the holder works worse. We advise picking the steel dimension according to the table below.

Standard neodymium magnets irreversibly lose strength past the thermal threshold. Watch out for overheating – heat can permanently destroy this magnet. With increasing heat, the neodymium's force temporarily lowers. Do not use this product close to ovens exceeding its working range. Ignoring the limit will lead to destruction of magnetic properties.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Flat magnets (pancake types) risk losing magnetic properties sooner than long magnets. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnets interact from a much further distance than a neodymium and metal combination. The connection of magnet-to-magnet produces a massive flux and a larger range of performance. Planning to create a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the collision energy is extreme. The levitation is marginally weaker than the attraction, but still impressive.
*Field value between like poles reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Attention: Figures refer to sliding force of two matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Safety (HSE) (implants) - warnings

Powerful magnet radiation is a real danger to IT equipment and pacemakers. These magnets generate a flux 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 drug dispensers. The risk also applies to: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

NdFeB products are delicate – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Impact energy can cause material chips or dangerous crushing to skin. Always hold the magnet during bringing near metal 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 working with large magnets.

Corrosion warning: 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. Buoyancy helps in lifting finds.

1. Shear force

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

2. Steel saturation

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

3. Temperature resistance

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.66

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.

The ring magnet with a hole MP 5x1.5x3 / 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 0.77 kg works great as a cabinet closure, speaker holder, or mounting element in devices.

This is a crucial issue when working with model MP 5x1.5x3 / 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.

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. This product is dedicated for indoor use. For outdoor applications, we recommend choosing rubberized holders or additional protection with varnish.

A screw or bolt with a thread diameter smaller than 1.5 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.

The presented product is a ring magnet with dimensions Ø5 mm (outer diameter) and height 3 mm. The pulling force of this model is an impressive 0.77 kg, which translates to 7.50 N in newtons. The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 1.5 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.

Strengths and weaknesses of rare earth magnets.

Pros

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
Magnets very well resist against demagnetization caused by ambient magnetic noise,
A magnet with a smooth gold surface has an effective appearance,
Neodymium magnets deliver maximum magnetic induction on a small area, which ensures high operational effectiveness,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Possibility of accurate shaping and adjusting to atypical requirements,
Universal use in modern industrial fields – they find application in HDD drives, electric drive systems, medical devices, as well as complex engineering applications.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Limitations

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum holding power of the magnet – what it depends on?

Magnet power was defined for optimal configuration, including:

using a base made of mild steel, functioning as a circuit closing element
whose transverse dimension is min. 10 mm
with an ideally smooth touching surface
under conditions of no distance (surface-to-surface)
under vertical force vector (90-degree angle)
at conditions approx. 20°C

Impact of factors on magnetic holding capacity in practice

Real force is influenced by working environment parameters, including (from priority):

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Direction of force – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
Plate thickness – insufficiently thick steel does not close the flux, causing part of the flux to be lost into the air.
Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
Surface condition – ground elements ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Precautions when working with NdFeB magnets

Impact on smartphones

Remember: neodymium magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.

Serious injuries

Large magnets can break fingers in a fraction of a second. Do not put your hand between two attracting surfaces.

Nickel allergy

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease handling magnets and wear gloves.

Do not underestimate power

Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.

Machining danger

Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.

ICD Warning

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

Electronic devices

Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.

Do not give to children

NdFeB magnets are not intended for children. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires urgent medical intervention.

Heat sensitivity

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Eye protection

Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
