Technical simulation of the magnet - report

The following information represent the direct effect of a engineering simulation. Results are based on models for the class Nd₂Fe₁₄B. Real-world parameters may differ from theoretical values. Treat these data as a preliminary roadmap during assembly planning.

Grip strength weakens significantly with every mm of gap. Note that even a microscopic distance (e.g., dirt, varnish, dust) noticeably reduces the pull force. Neodymiums work optimally at the point of direct contact; air break nullifies the power. Analyze how quickly the parameters fall, when the magnet does not adhere tightly to the metal substrate. When planning the assembly, avoid additional spacers.

This section defines the approximate force needed to initiate the downward movement of the magnet down against a vertical steel plate (considering typical friction coefficient). This parameter is relative to the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - 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 pounds 231.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.34 pounds 154.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 pounds 77.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.39 kg / 0.85 pounds 385.0 g / 3.8 N

When mounting a magnet on a upright surface (e.g., a fridge), it you can count on only approx. 1/5 of nominal attraction strength. Gravity and a weak degree of grip mean that magnets slip easier than they detach. Want to create a hanger? Note that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a noticeably lighter cargo. Application of an anti-slip layer can drastically raise the stability.

10 mm	100%	0.77 kg / 1.70 pounds 770.0 g / 7.6 N
11 mm	100%	0.77 kg / 1.70 pounds 770.0 g / 7.6 N
12 mm	100%	0.77 kg / 1.70 pounds 770.0 g / 7.6 N

A thin metal plate is incapable of focus the entire magnetic field, which weakens actual performance of the magnet. If you mount a strong magnet to a thin surface, the flux will pass right through and the holding will be smaller. To squeeze 100% of this neodymium's power, you need a suitably thick backing of steel. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the magnet shows lower pull force. We recommend selecting the steel dimension from these parameters.

Ordinary NdFeB products irreversibly lose parameters above the temperature limit. Watch out for overheating – excessive heat can irreversibly damage this magnet. With every degree above norm, the magnet's capacity briefly decreases. Refrain from using this product close to heaters higher than its operating temperature limit. Exceeding the critical threshold will lead to destruction of magnetic properties.

*Important note: Thermal stability is determined by both grade, but also on the magnet's shape. Flat magnets (pancake types) risk losing magnetic properties under lower heat stress than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and sheet setup. Such a system of two magnets generates a stronger field and a wider radius of action. Planning to create a strong closure? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when connecting a pair of magnets, the collision energy is huge. The repulsion force is marginally weaker than the attraction, but still significant.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Important: Estimates apply to sliding force of two same magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to electronic devices and pacemakers. These NdFeB products produce a field that destroys function of sensitive medical devices. Remember: the unseen radiation penetrates the body and glass. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - warning
MP 5x1.5x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	44.27 km/h (12.30 m/s)	0.03 J
30 mm	76.64 km/h (21.29 m/s)	0.09 J
50 mm	98.94 km/h (27.48 m/s)	0.15 J
100 mm	139.93 km/h (38.87 m/s)	0.30 J

NdFeB products are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Striking energy can destroy the magnet or dangerous crushing to skin. Always hold the magnet during installation so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the neodymium. Use safety goggles when playing with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds merely approx. 20-30% of its perpendicular strength.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) significantly weakens the holding force.

3. Heat tolerance

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

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

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

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. Thanks to the hole (often for a screw), this model enables quick installation to wood, wall, plastic, or metal. 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 5x1.5x3 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. When tightening the screw, you must maintain great sensitivity. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force 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 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.

A screw or bolt with a thread diameter smaller than 1.5 mm fits this model. 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 3 mm. The key parameter here is the holding force amounting to approximately 0.77 kg (force ~7.50 N). 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. 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 neodymium magnets.

Benefits

Besides their tremendous field intensity, neodymium magnets offer the following advantages:

They do not lose magnetism, even after nearly ten years – the decrease in strength is only ~1% (according to tests),
They are resistant to demagnetization induced by presence of other magnetic fields,
By covering with a shiny layer of silver, the element presents an nice look,
They are known for high magnetic induction at the operating surface, making them more effective,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Thanks to modularity in shaping and the ability to customize to client solutions,
Significant place in advanced technology sectors – they are used in magnetic memories, electric motors, precision medical tools, as well as multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing nuts and complex forms in magnets, we recommend using cover - magnetic mechanism.
Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Highest magnetic holding force – what affects it?

The lifting capacity listed is a measurement result conducted under standard conditions:

on a base made of mild steel, optimally conducting the magnetic flux
whose transverse dimension is min. 10 mm
characterized by smoothness
under conditions of gap-free contact (surface-to-surface)
under vertical force vector (90-degree angle)
in temp. approx. 20°C

What influences lifting capacity in practice

Please note that the magnet holding will differ subject to elements below, starting with the most relevant:

Distance (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, rust or debris).
Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Warnings

Operating temperature

Keep cool. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).

Eye protection

Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Threat to electronics

Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.

Precision electronics

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

Medical interference

People with a pacemaker have to maintain an safe separation from magnets. The magnetism can interfere with the operation of the implant.

Metal Allergy

A percentage of the population experience a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in dermatitis. We strongly advise wear safety gloves.

Safe operation

Handle magnets with awareness. Their powerful strength can shock even experienced users. Plan your moves and do not underestimate their power.

Crushing risk

Pinching hazard: The attraction force is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.

This is not a toy

Neodymium magnets are not toys. Eating multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.

Fire risk

Powder generated during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Important! More info about risks in the article: Magnet Safety Guide.
