Advantages and disadvantages of rare earth magnets.
Pros
- Their strength is durable, and after approximately ten years it drops only by ~1% (according to research),
- Neodymium magnets remain extremely resistant to demagnetization caused by magnetic disturbances,
- By applying a lustrous layer of gold, the element has an proper look,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the ability of free forming and adaptation to individualized requirements, neodymium magnets can be manufactured in a variety of forms and dimensions, which increases their versatility,
- Fundamental importance in high-tech industry – they are commonly used in magnetic memories, drive modules, advanced medical instruments, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in compact constructions
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB 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 very resistant to heat
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated forms in magnets, we recommend using casing - magnetic holder.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small components of these products are able to be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Magnetic strength at its maximum – what contributes to it?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- whose transverse dimension reaches at least 10 mm
- with a plane perfectly flat
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Clearance – the presence of any layer (rust, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Smoothness – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Cards and drives
Equipment safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
Safe operation
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Material brittleness
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets leads to them cracking into small pieces.
This is not a toy
Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are life-threatening.
Metal Allergy
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, refrain from direct skin contact and select encased magnets.
Demagnetization risk
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.
Do not drill into magnets
Powder produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Serious injuries
Big blocks can smash fingers instantly. Under no circumstances put your hand between two attracting surfaces.
Warning for heart patients
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Compass and GPS
A powerful magnetic field interferes with the operation of compasses in phones and navigation systems. Maintain magnets close to a smartphone to avoid breaking the sensors.
