1. Shear force
*Caution: On a vertical wall, the magnet retains only ~20% of its nominal pull.
2. Steel thickness impact
*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.
3. Thermal stability
*For standard magnets, the safety limit is 80°C.
4. Demagnetization curve and operating point (B-H)
chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.35
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.

Pros as well as cons of rare earth magnets.
Pros
- Their strength remains stable, and after approximately 10 years it drops only by ~1% (theoretically),
- They show high resistance to demagnetization induced by external magnetic fields,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They show high magnetic induction at the operating surface, which increases their power,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of accurate machining as well as modifying to defined needs,
- Significant place in advanced technology sectors – they are commonly used in computer drives, electric drive systems, advanced medical instruments, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these magnets can complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- using a plate made of low-carbon steel, serving as a magnetic yoke
- whose thickness reaches at least 10 mm
- with a surface cleaned and smooth
- without any clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Gap (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be escaped into the air.
- Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Crushing risk
Danger of trauma: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Magnets are brittle
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Protect data
Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Powerful field
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
ICD Warning
For implant holders: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Power loss in heat
Avoid heat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Warning for allergy sufferers
A percentage of the population suffer from a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching may cause a rash. We recommend use protective gloves.
Precision electronics
An intense magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a device to prevent breaking the sensors.
Keep away from children
Always keep magnets out of reach of children. Ingestion danger is significant, and the effects of magnets connecting inside the body are tragic.
Dust explosion hazard
Dust created during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
