1. Wall mount (shear)
*Caution: On a vertical surface, the magnet holds only approx. 20-30% of its max power.
2. Steel saturation
*Thin metal sheet (e.g. computer case) drastically weakens the holding force.
3. Temperature resistance
*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) = 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.

Other products
Advantages as well as disadvantages of neodymium magnets.
Benefits
- Their strength remains stable, and after around ten years it decreases only by ~1% (theoretically),
- They do not lose their magnetic properties even under close interference source,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets ensure 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 form) at temperatures up to 230°C and above...
- Thanks to flexibility in constructing and the capacity to modify to individual projects,
- Wide application in electronics industry – they find application in HDD drives, electric motors, diagnostic systems, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions
Weaknesses
- At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- 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, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum lifting capacity of the magnet – what contributes to it?
- on a block made of mild steel, effectively closing the magnetic flux
- possessing a massiveness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- without any clearance between the magnet and steel
- under vertical force vector (90-degree angle)
- at standard ambient temperature
Magnet lifting force in use – key factors
- Clearance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin steel does not close the flux, causing part of the power to be wasted into the air.
- Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Keep away from children
Product intended for adults. Small elements pose a choking risk, leading to intestinal necrosis. Keep out of reach of kids and pets.
Serious injuries
Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!
Magnets are brittle
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Combustion hazard
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Allergic reactions
Certain individuals experience a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to dermatitis. We strongly advise wear protective gloves.
Thermal limits
Do not overheat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Data carriers
Avoid bringing magnets close to a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
ICD Warning
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Magnetic interference
An intense magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a smartphone to avoid breaking the sensors.
Do not underestimate power
Handle with care. Neodymium magnets attract from a distance and snap with huge force, often quicker than you can move away.
