1. Sliding resistance
*Note: On a vertical surface, the magnet retains just ~20% of its perpendicular strength.
2. Efficiency vs thickness
*Thin metal sheet (e.g. 0.5mm PC case) drastically limits the holding force.
3. Temperature resistance
*For N38 grade, the safety limit is 80°C.
4. Demagnetization curve and operating point (B-H)
chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.27
The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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.

Advantages and disadvantages of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- Neodymium magnets are highly resistant to loss of magnetic properties caused by external field sources,
- In other words, due to the metallic surface of silver, the element gains visual value,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- 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...
- Thanks to the ability of precise shaping and adaptation to specialized projects, neodymium magnets can be modeled in a wide range of geometric configurations, which makes them more universal,
- Significant place in advanced technology sectors – they serve a role in magnetic memories, electromotive mechanisms, diagnostic systems, as well as industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in strength. 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 rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating nuts and complex forms in magnets, we recommend using a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- without the slightest air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Magnet lifting force in use – key factors
- Clearance – the presence of any layer (paint, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material composition – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Plate texture – ground elements ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the load capacity.
Warnings
Magnet fragility
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them breaking into shards.
GPS Danger
Note: neodymium magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness appears, cease handling magnets and wear gloves.
Do not underestimate power
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Dust is flammable
Dust produced during machining of magnets is flammable. Do not drill into magnets unless you are an expert.
Magnetic media
Avoid bringing magnets near a purse, computer, or TV. The magnetism can destroy these devices and erase data from cards.
Heat warning
Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Crushing risk
Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Medical interference
People with a heart stimulator must maintain an absolute distance from magnets. The magnetism can stop the functioning of the implant.
Keep away from children
Only for adults. Small elements can be swallowed, causing intestinal necrosis. Store out of reach of children and animals.
