Strengths and weaknesses of rare earth magnets.
Pros
- They retain magnetic properties for around 10 years – the loss is just ~1% (according to analyses),
- They have excellent resistance to weakening of magnetic properties when exposed to external fields,
- By using a decorative coating of nickel, the element presents an aesthetic look,
- Magnets exhibit maximum magnetic induction on the working surface,
- 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...
- Thanks to flexibility in shaping and the capacity to adapt to individual projects,
- Universal use in future technologies – they are used in HDD drives, brushless drives, precision medical tools, and industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- 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 durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in creating threads and complicated shapes in magnets, we propose using a housing - magnetic mount.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- whose transverse dimension is min. 10 mm
- with a plane free of scratches
- under conditions of no distance (metal-to-metal)
- under axial force vector (90-degree angle)
- at room temperature
Practical aspects of lifting capacity – factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Angle of force application – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the holding force.
Warnings
Phone sensors
GPS units and smartphones are highly susceptible to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Eye protection
Neodymium magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them shattering into small pieces.
Medical interference
Individuals with a ICD should maintain an safe separation from magnets. The magnetism can stop the operation of the life-saving device.
Threat to electronics
Data protection: Neodymium magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Do not overheat magnets
Keep cool. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Combustion hazard
Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Avoid contact if allergic
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease handling magnets and use protective gear.
Caution required
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
This is not a toy
NdFeB magnets are not toys. Accidental ingestion of several magnets may result in them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.
Bone fractures
Risk of injury: The pulling power is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
