1. Shear force
*Warning: On a vertical wall, the magnet retains only a fraction of its nominal pull.
2. Steel saturation
*Thin metal sheet (e.g. computer case) significantly weakens the holding force.
3. Temperature resistance
*For N38 material, the critical limit is 80°C.

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.84
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.

Strengths and weaknesses of neodymium magnets.
Strengths
- They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- They do not lose their magnetic properties even under external field action,
- In other words, due to the glossy finish of silver, the element becomes visually attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of exact forming as well as adapting to individual requirements,
- Huge importance in modern industrial fields – they find application in data components, motor assemblies, diagnostic systems, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- We suggest a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a base made of structural steel, effectively closing the magnetic field
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ground contact surface
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Safe handling of neodymium magnets
Respect the power
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Safe distance
Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Danger to pacemakers
Individuals with a ICD should maintain an absolute distance from magnets. The magnetism can interfere with the functioning of the life-saving device.
Serious injuries
Big blocks can crush fingers in a fraction of a second. Never put your hand between two attracting surfaces.
Keep away from electronics
A powerful magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid breaking the sensors.
Do not give to children
Strictly keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are life-threatening.
Dust explosion hazard
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Maximum temperature
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Warning for allergy sufferers
Certain individuals suffer from a sensitization to Ni, which is the standard coating for neodymium magnets. Prolonged contact may cause skin redness. We strongly advise wear safety gloves.
Beware of splinters
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
