1. Wall mount (shear)
*Warning: On a vertical wall, the magnet retains just a fraction of its max power.
2. Efficiency vs thickness
*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces the holding force.
3. Power loss vs temp
*For N38 grade, 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.

Other proposals
Advantages and disadvantages of rare earth magnets.
Pros
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- They maintain their magnetic properties even under close interference source,
- By covering with a shiny coating of gold, the element gains an professional look,
- Neodymium magnets ensure maximum magnetic induction on a small area, which ensures high operational effectiveness,
- 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...
- Possibility of individual machining and optimizing to specific conditions,
- Huge importance in future technologies – they serve a role in magnetic memories, drive modules, precision medical tools, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of producing nuts in the magnet and complicated shapes - recommended is a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Highest magnetic holding force – what contributes to it?
- with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- without any clearance between the magnet and steel
- under axial force vector (90-degree angle)
- at ambient temperature room level
Magnet lifting force in use – key factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Danger to pacemakers
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Keep away from electronics
GPS units and smartphones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Electronic hazard
Equipment safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Dust explosion hazard
Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Do not overheat magnets
Keep cool. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Beware of splinters
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Finger safety
Large magnets can break fingers in a fraction of a second. Never place your hand between two strong magnets.
Immense force
Handle magnets consciously. Their immense force can surprise even professionals. Be vigilant and do not underestimate their power.
Adults only
Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Store away from kids and pets.
Metal Allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
