1. Wall mount (shear)
*Warning: On a vertical wall, the magnet retains just approx. 20-30% of its max power.
2. Steel thickness impact
*Thin steel (e.g. 0.5mm PC case) significantly limits the holding force.
3. Temperature resistance
*For N38 material, the critical limit is 80°C.
4. Demagnetization curve and operating point (B-H)
chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.66
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 Pc (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 Pc 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.

Pros and cons of rare earth magnets.
Benefits
- They have stable power, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
- Neodymium magnets are characterized by extremely resistant to demagnetization caused by external interference,
- In other words, due to the aesthetic surface of nickel, the element becomes visually attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to the option of free forming and customization to individualized solutions, magnetic components can be modeled in a broad palette of geometric configurations, which makes them more universal,
- Wide application in modern industrial fields – they serve a role in magnetic memories, electric drive systems, diagnostic systems, also modern systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of producing nuts in the magnet and complex shapes - preferred is a housing - magnetic holder.
- Health risk to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small components of these products can disrupt the diagnostic process medical when they are in 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
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a sheet made of low-carbon steel, serving as a ideal flux conductor
- whose thickness equals approx. 10 mm
- with an ground contact surface
- with total lack of distance (without impurities)
- during detachment in a direction perpendicular to the plane
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Distance – existence of any layer (rust, dirt, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick sheet does not close the flux, causing part of the flux to be escaped to the other side.
- Material type – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.
Safe handling of neodymium magnets
Danger to pacemakers
Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Swallowing risk
Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.
Crushing force
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Magnetic interference
Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Nickel allergy
Some people experience a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Extended handling may cause an allergic reaction. We strongly advise wear protective gloves.
Risk of cracking
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Keep away from computers
Avoid bringing magnets near a purse, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Machining danger
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Conscious usage
Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their power.
Heat sensitivity
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
