1. Wall mount (shear)
*Caution: On a vertical wall, the magnet holds only approx. 20-30% of its max power.
2. Steel saturation
*Thin steel (e.g. computer case) severely 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) = 0.74
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.

Other products
Advantages and disadvantages of rare earth magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- Magnets perfectly resist against loss of magnetization caused by ambient magnetic noise,
- A magnet with a metallic gold surface has an effective appearance,
- They feature high magnetic induction at the operating surface, making them more effective,
- 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 flexibility in designing and the ability to customize to specific needs,
- Versatile presence in future technologies – they serve a role in computer drives, brushless drives, medical devices, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited ability of making nuts in the magnet and complicated forms - preferred is cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these products can complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a plate made of structural steel, effectively closing the magnetic field
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface free of scratches
- with zero gap (without paint)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
- Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the holding force.
Safe handling of neodymium magnets
Bodily injuries
Big blocks can break fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.
Keep away from children
Only for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep away from kids and pets.
Keep away from computers
Device Safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Magnets are brittle
Neodymium magnets are sintered ceramics, which means they are very brittle. Collision of two magnets leads to them breaking into small pieces.
Pacemakers
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Heat sensitivity
Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its properties and pulling force.
Compass and GPS
An intense magnetic field interferes with the operation of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Nickel allergy
Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness appears, cease working with magnets and use protective gear.
Caution required
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Mechanical processing
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
