1. Vertical hold
*Warning: On a vertical wall, the magnet holds only ~20% of its nominal pull.
2. Plate thickness effect
*Thin steel (e.g. computer case) severely reduces the holding force.
3. Heat tolerance
*For N38 grade, the critical 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.

Other offers
Pros and cons of neodymium magnets.
Benefits
- They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They show high resistance to demagnetization induced by external disturbances,
- A magnet with a metallic silver surface looks better,
- Magnets exhibit huge magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of custom forming as well as modifying to defined conditions,
- Huge importance in future technologies – they are utilized in magnetic memories, drive modules, medical devices, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in realizing nuts and complex shapes in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products can complicate diagnosis medical in case of swallowing.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- on a plate made of structural steel, optimally conducting the magnetic field
- with a thickness minimum 10 mm
- with an ground contact surface
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- at temperature room level
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Material type – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal factor – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
Heat warning
Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Handling guide
Exercise caution. Rare earth magnets act from a distance and snap with huge force, often faster than you can react.
Product not for children
NdFeB magnets are not intended for children. Swallowing several magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires immediate surgery.
Beware of splinters
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets will cause them breaking into shards.
Impact on smartphones
Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Fire risk
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Electronic hazard
Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.
Bodily injuries
Risk of injury: The attraction force is so great that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Danger to pacemakers
For implant holders: Powerful magnets disrupt electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Avoid contact if allergic
Medical facts indicate that the nickel plating (the usual finish) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands and choose coated magnets.
