1. Shear force
*Note: On a vertical wall, the magnet retains merely ~20% of its perpendicular strength.
2. Steel thickness impact
*Thin metal sheet (e.g. computer case) significantly limits the holding force.
3. Thermal stability
*For standard magnets, the critical limit is 80°C.
4. Demagnetization curve and operating point (B-H)
chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.84
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.

Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They have unchanged lifting capacity, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by external disturbances,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- In view of the potential of precise forming and adaptation to specialized solutions, magnetic components can be created in a variety of forms and dimensions, which amplifies use scope,
- Key role in modern industrial fields – they are used in mass storage devices, electric drive systems, precision medical tools, also technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as 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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest a housing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a plate made of structural steel, optimally conducting the magnetic flux
- with a thickness no less than 10 mm
- with an ideally smooth touching surface
- under conditions of gap-free contact (surface-to-surface)
- under perpendicular force direction (90-degree angle)
- at temperature room level
Determinants of practical lifting force of a magnet
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the flux to be escaped to the other side.
- Metal type – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the load capacity.
H&S for magnets
Power loss in heat
Keep cool. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Crushing risk
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Fragile material
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Health Danger
Individuals with a ICD must keep an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.
Allergic reactions
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If you have an allergy, prevent direct skin contact or choose encased magnets.
Choking Hazard
Absolutely store magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are life-threatening.
Keep away from computers
Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Impact on smartphones
GPS units and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Do not drill into magnets
Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Conscious usage
Handle with care. Rare earth magnets act from a distance and snap with massive power, often faster than you can move away.
