Pros and cons of rare earth magnets.
Benefits
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They do not lose their magnetic properties even under strong external field,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets generate maximum magnetic induction on a small surface, which allows for strong attraction,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- In view of the potential of free forming and customization to individualized solutions, neodymium magnets can be modeled in a broad palette of shapes and sizes, which increases their versatility,
- Wide application in future technologies – they are commonly used in computer drives, brushless drives, advanced medical instruments, as well as other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in realizing threads and complex shapes in magnets, we recommend using a housing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a plate made of low-carbon steel, acting as a magnetic yoke
- possessing a thickness of min. 10 mm to avoid saturation
- with a plane perfectly flat
- under conditions of gap-free contact (metal-to-metal)
- during detachment in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Key elements affecting lifting force
- Gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Alloy steels decrease magnetic properties and holding force.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit 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 attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Magnetic interference
An intense magnetic field disrupts the functioning of compasses in phones and GPS navigation. Maintain magnets close to a device to prevent breaking the sensors.
Conscious usage
Handle with care. Neodymium magnets act from a long distance and snap with massive power, often faster than you can move away.
Shattering risk
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets will cause them cracking into shards.
Dust is flammable
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Pinching danger
Large magnets can break fingers instantly. Never place your hand betwixt two attracting surfaces.
Demagnetization risk
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
Metal Allergy
It is widely known that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, prevent direct skin contact or choose encased magnets.
Magnetic media
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Health Danger
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Danger to the youngest
Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Store away from kids and pets.
