1. Shear force
*Caution: On a vertical surface, the magnet holds just ~20% of its perpendicular strength.
2. Efficiency vs thickness
*Thin steel (e.g. computer case) significantly 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) = 0.25
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.

Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They retain attractive force for nearly ten years – the drop is just ~1% (according to analyses),
- Magnets very well defend themselves against demagnetization caused by external fields,
- A magnet with a metallic nickel surface has better aesthetics,
- Neodymium magnets create maximum magnetic induction on a small area, which allows for strong attraction,
- 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...
- Due to the possibility of precise molding and adaptation to individualized projects, neodymium magnets can be created in a variety of forms and dimensions, which makes them more universal,
- Universal use in high-tech industry – they serve a role in magnetic memories, electric motors, precision medical tools, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making threads in the magnet and complex forms - preferred is a housing - magnet mounting.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these products can complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- using a base made of high-permeability steel, acting as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- characterized by smoothness
- without any insulating layer between the magnet and steel
- under vertical force direction (90-degree angle)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Clearance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – ideal substrate is high-permeability steel. Stainless steels may attract less.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Keep away from computers
Do not bring magnets close to a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Bodily injuries
Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
Dust explosion hazard
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Magnetic interference
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Handling guide
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Beware of splinters
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
ICD Warning
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
No play value
Absolutely store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are fatal.
Skin irritation risks
Some people suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Extended handling can result in an allergic reaction. We recommend use safety gloves.
Do not overheat magnets
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. This process is irreversible.
