Pros and cons of neodymium magnets.
Advantages
- They do not lose magnetism, even over approximately 10 years – the drop in lifting capacity is only ~1% (based on measurements),
- Neodymium magnets prove to be exceptionally resistant to loss of magnetic properties caused by magnetic disturbances,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to modularity in designing and the capacity to customize to complex applications,
- Versatile presence in future technologies – they find application in hard drives, brushless drives, advanced medical instruments, also industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose their strength 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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic holder, due to difficulties in creating threads inside the magnet and complex shapes.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- whose transverse dimension is min. 10 mm
- with an polished contact surface
- under conditions of gap-free contact (metal-to-metal)
- under axial force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance – the presence of foreign body (rust, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and holding force.
- Surface structure – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Operating temperature – 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 measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Warnings
Crushing force
Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Do not underestimate power
Handle magnets with awareness. Their powerful strength can surprise even professionals. Stay alert and respect their force.
Power loss in heat
Do not overheat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Do not drill into magnets
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Cards and drives
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).
Warning for allergy sufferers
Studies show that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent direct skin contact and select encased magnets.
Keep away from electronics
Navigation devices and mobile phones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
This is not a toy
Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Keep away from kids and pets.
Medical implants
For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Magnet fragility
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
