1. Sliding resistance
*Warning: On a vertical wall, the magnet holds just approx. 20-30% of its perpendicular strength.
2. Steel saturation
*Thin steel (e.g. 0.5mm PC case) significantly weakens the holding force.
3. Thermal stability
*For standard magnets, the max working temp is 80°C.
4. Demagnetization curve and operating point (B-H)
chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.59
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 neodymium magnets.
Pros
- They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are characterized by remarkably resistant to loss of magnetic properties caused by external field sources,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the surface of the magnet turns out to be extremely intense,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Due to the possibility of accurate shaping and customization to custom requirements, magnetic components can be created in a broad palette of forms and dimensions, which expands the range of possible applications,
- Huge importance in modern technologies – they are used in magnetic memories, electric motors, diagnostic systems, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in special holders. 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 advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating threads and complicated shapes in magnets, we propose using casing - magnetic holder.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a plane perfectly flat
- with total lack of distance (without impurities)
- during detachment in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Clearance – the presence of foreign body (paint, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
H&S for magnets
Swallowing risk
NdFeB magnets are not intended for children. Eating several magnets may result in them attracting across intestines, which constitutes a severe health hazard and requires urgent medical intervention.
Flammability
Powder generated during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Caution required
Be careful. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can move away.
Fragile material
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Implant safety
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Threat to electronics
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Operating temperature
Keep cool. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Impact on smartphones
Remember: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
Pinching danger
Danger of trauma: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Allergic reactions
Some people suffer from a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Extended handling might lead to dermatitis. We recommend use safety gloves.
