1. Vertical hold
*Caution: On a vertical surface, the magnet retains just approx. 20-30% of its perpendicular strength.
2. Steel saturation
*Thin steel (e.g. computer case) severely 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) = 0.25
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 as well as weaknesses of rare earth magnets.
Pros
- They have unchanged lifting capacity, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- They feature excellent resistance to magnetism drop when exposed to external fields,
- A magnet with a smooth silver surface looks better,
- Magnets have huge magnetic induction on the working surface,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in designing and the ability to customize to unusual requirements,
- Key role in innovative solutions – they are used in mass storage devices, drive modules, precision medical tools, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- 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
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using cover - magnetic mount.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these products are able to complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a block made of mild steel, effectively closing the magnetic flux
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an polished contact surface
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
Practical aspects of lifting capacity – factors
- Distance (betwixt the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Alloy admixtures decrease magnetic properties and lifting capacity.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Safety rules for work with NdFeB magnets
Protect data
Do not bring magnets close to a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Physical harm
Pinching hazard: The pulling power is so immense that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Dust explosion hazard
Machining of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Fragile material
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Compass and GPS
A powerful magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Maintain magnets near a device to prevent breaking the sensors.
Do not overheat magnets
Watch the temperature. Exposing the magnet to high heat will destroy its properties and pulling force.
Swallowing risk
Absolutely store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are tragic.
Immense force
Use magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their power.
Health Danger
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Nickel coating and allergies
Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands and select encased magnets.
