Advantages and disadvantages of rare earth magnets.
Advantages
- They have stable power, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
- They are resistant to demagnetization induced by external field influence,
- A magnet with a metallic nickel surface is more attractive,
- Magnetic induction on the working layer of the magnet remains exceptional,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
- Thanks to modularity in shaping and the capacity to customize to client solutions,
- Universal use in future technologies – they are used in mass storage devices, drive modules, medical equipment, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited ability of producing threads in the magnet and complex forms - recommended is casing - magnetic holder.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these devices are able to complicate diagnosis 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
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- with a thickness minimum 10 mm
- with an ground touching surface
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction perpendicular to the mounting surface
- at temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and holding force.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Electronic hazard
Data protection: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
Magnetic interference
GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
Health Danger
Patients with a ICD must keep an absolute distance from magnets. The magnetism can interfere with the operation of the implant.
Bone fractures
Watch your fingers. Two large magnets will join instantly with a force of massive weight, destroying anything in their path. Be careful!
Safe operation
Be careful. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can react.
Risk of cracking
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Swallowing risk
Only for adults. Small elements can be swallowed, leading to severe trauma. Store away from children and animals.
Warning for allergy sufferers
Certain individuals experience a contact allergy to Ni, which is the standard coating for NdFeB magnets. Prolonged contact might lead to a rash. It is best to use protective gloves.
Thermal limits
Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).
Mechanical processing
Machining of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
