1. Sliding resistance
*Warning: On a vertical wall, the magnet retains merely ~20% of its max power.
2. Plate thickness effect
*Thin steel (e.g. 0.5mm PC case) severely limits the holding force.
3. Temperature resistance
*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) = 0.84
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.

Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- They maintain their magnetic properties even under external field action,
- Thanks to the smooth finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an elegant appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Due to the potential of precise forming and customization to individualized requirements, NdFeB magnets can be modeled in a wide range of forms and dimensions, which amplifies use scope,
- Fundamental importance in modern industrial fields – they find application in magnetic memories, electromotive mechanisms, diagnostic systems, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complex forms - preferred is casing - mounting mechanism.
- Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- using a sheet made of high-permeability steel, functioning as a ideal flux conductor
- whose transverse dimension equals approx. 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- under axial application of breakaway force (90-degree angle)
- at ambient temperature room level
Magnet lifting force in use – key factors
- Gap (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin plate does not close the flux, causing part of the flux to be escaped to the other side.
- Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Safe handling of neodymium magnets
Magnetic interference
Navigation devices and mobile phones are highly susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Pinching danger
Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
Life threat
Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or request help to handle the magnets.
Fire warning
Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Sensitization to coating
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and use protective gear.
Do not overheat magnets
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Do not underestimate power
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Danger to the youngest
These products are not suitable for play. Swallowing multiple magnets may result in them pinching intestinal walls, which constitutes a critical condition and requires immediate surgery.
Protect data
Very strong magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Shattering risk
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them shattering into small pieces.
