1. Wall mount (shear)
*Caution: On a vertical wall, the magnet retains just ~20% of its perpendicular strength.
2. Steel thickness impact
*Thin steel (e.g. 0.5mm PC case) significantly 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) = 0.66
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.

Other products
Strengths as well as weaknesses of neodymium magnets.
Pros
- They do not lose power, even after around ten years – the reduction in power is only ~1% (theoretically),
- They have excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
- A magnet with a smooth silver surface has an effective appearance,
- Neodymium magnets generate maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- In view of the potential of precise molding and customization to individualized solutions, magnetic components can be produced in a variety of geometric configurations, which amplifies use scope,
- Huge importance in innovative solutions – they are utilized in hard drives, electric motors, medical devices, and multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- on a block made of structural steel, optimally conducting the magnetic flux
- possessing a thickness of min. 10 mm to avoid saturation
- with an polished touching surface
- with zero gap (no paint)
- for force applied at a right angle (pull-off, not shear)
- at standard ambient temperature
Magnet lifting force in use – key factors
- Gap (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Metal type – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Bodily injuries
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Pacemakers
Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Warning for allergy sufferers
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, immediately stop working with magnets and use protective gear.
Dust is flammable
Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Keep away from electronics
Remember: neodymium magnets produce a field that confuses sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
Magnets are brittle
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Safe distance
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
Do not underestimate power
Handle with care. Rare earth magnets act from a distance and connect with huge force, often faster than you can move away.
Choking Hazard
Always store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are life-threatening.
Operating temperature
Keep cool. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
