1. Vertical hold
*Caution: On a vertical surface, the magnet holds just approx. 20-30% of its nominal pull.
2. Efficiency vs thickness
*Thin steel (e.g. 0.5mm PC case) significantly weakens the holding force.
3. Temperature resistance
*For N38 material, the max working temp is 80°C.
4. Demagnetization curve and operating point (B-H)
chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.29
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.
Benefits
- They do not lose magnetism, even during nearly 10 years – the decrease in lifting capacity is only ~1% (based on measurements),
- Magnets effectively resist against demagnetization caused by external fields,
- A magnet with a metallic nickel surface has an effective appearance,
- Neodymium magnets create maximum magnetic induction on a their surface, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- In view of the potential of free forming and adaptation to specialized solutions, neodymium magnets can be produced in a variety of forms and dimensions, which increases their versatility,
- Versatile presence in electronics industry – they are used in data components, motor assemblies, precision medical tools, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in small systems
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects 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 strength 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
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing threads in the magnet and complex forms - preferred is a housing - magnet mounting.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, tiny parts of these products can be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the application of a yoke made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a surface perfectly flat
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically 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.
- Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Data carriers
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Keep away from children
These products are not toys. Accidental ingestion of several magnets may result in them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
Immense force
Handle with care. Neodymium magnets attract from a distance and snap with huge force, often faster than you can move away.
Material brittleness
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Demagnetization risk
Watch the temperature. Heating the magnet to high heat will destroy its magnetic structure and strength.
Fire risk
Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
Pacemakers
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
GPS Danger
A powerful magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Keep magnets close to a device to avoid damaging the sensors.
Finger safety
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness occurs, cease working with magnets and use protective gear.
