1. Wall mount (shear)
*Warning: On a vertical wall, the magnet holds merely ~20% of its perpendicular strength.
2. Efficiency vs thickness
*Thin steel (e.g. computer case) severely weakens the holding force.
3. Temperature resistance
*For standard magnets, 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
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.

Strengths and weaknesses of neodymium magnets.
Advantages
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- Magnets effectively defend themselves against loss of magnetization caused by external fields,
- Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
- They feature high magnetic induction at the operating surface, which increases their power,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
- Thanks to modularity in constructing and the ability to modify to individual projects,
- Versatile presence in innovative solutions – they serve a role in magnetic memories, drive modules, advanced medical instruments, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves 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, as well as 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 suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited ability of producing nuts in the magnet and complicated forms - recommended is a housing - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small components of these products can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of low-carbon steel, functioning as a circuit closing element
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a surface perfectly flat
- with total lack of distance (without paint)
- under axial force vector (90-degree angle)
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Distance (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the power to be lost into the air.
- Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was checked 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 and the plate reduces the holding force.
Safety rules for work with NdFeB magnets
Magnets are brittle
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
Adults only
Always store magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are life-threatening.
Machining danger
Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Maximum temperature
Avoid heat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Skin irritation risks
Studies show that nickel (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands and opt for coated magnets.
Magnetic media
Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Conscious usage
Handle magnets consciously. Their immense force can shock even professionals. Plan your moves and respect their power.
Pacemakers
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
GPS Danger
GPS units and smartphones are extremely sensitive to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Bone fractures
Pinching hazard: The attraction force is so immense that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
