1. Sliding resistance
*Warning: On a vertical wall, the magnet retains only approx. 20-30% of its nominal pull.
2. Steel thickness impact
*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces the holding force.
3. Heat tolerance
*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) = 1.09
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.
Strengths
- Their magnetic field is maintained, and after around 10 years it drops only by ~1% (theoretically),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the aesthetic layer of silver, the element gains a professional look,
- Magnets possess extremely high magnetic induction on the working surface,
- 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 modularity in shaping and the ability to customize to unusual requirements,
- Huge importance in modern technologies – they are used in data components, electromotive mechanisms, medical devices, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Limited ability of producing threads in the magnet and complicated forms - recommended is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these magnets can complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- using a base made of high-permeability steel, serving as a circuit closing element
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by even structure
- under conditions of ideal adhesion (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Determinants of practical lifting force of a magnet
- Clearance – the presence of foreign body (paint, tape, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick steel does not close the flux, causing part of the power to be wasted into the air.
- Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Warning for allergy sufferers
Some people experience a contact allergy to Ni, which is the common plating for neodymium magnets. Extended handling can result in a rash. We suggest use protective gloves.
Health Danger
For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Hand protection
Danger of trauma: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Beware of splinters
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them breaking into shards.
Demagnetization risk
Avoid heat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Dust is flammable
Dust produced during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Magnetic interference
GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Handling rules
Handle magnets with awareness. Their immense force can surprise even professionals. Stay alert and respect their force.
Keep away from computers
Equipment safety: Strong magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).
Danger to the youngest
Strictly keep magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are life-threatening.
