Pros and cons of Nd2Fe14B magnets.
Pros
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (according to theory),
- They have excellent resistance to magnetic field loss as a result of opposing magnetic fields,
- In other words, due to the metallic finish of silver, the element looks attractive,
- Magnetic induction on the working part of the magnet is exceptional,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of detailed shaping as well as optimizing to complex conditions,
- Significant place in high-tech industry – they serve a role in HDD drives, drive modules, advanced medical instruments, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Disadvantages
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 extremely resistant to heat
- 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 secure oxidation as well as corrosion.
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using a housing - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these devices can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum magnetic pulling force – what contributes to it?
- using a base made of low-carbon steel, acting as a ideal flux conductor
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an ideally smooth contact surface
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at standard ambient temperature
Magnet lifting force in use – key factors
- Distance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy steels decrease magnetic permeability and lifting capacity.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
H&S for magnets
Avoid contact if allergic
Studies show that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, refrain from direct skin contact and opt for versions in plastic housing.
Data carriers
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
ICD Warning
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Safe operation
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Product not for children
These products are not suitable for play. Swallowing several magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires urgent medical intervention.
GPS Danger
A strong magnetic field interferes with the operation of compasses in smartphones and navigation systems. Maintain magnets close to a device to avoid damaging the sensors.
Shattering risk
Neodymium magnets are ceramic materials, which means they are very brittle. Collision of two magnets will cause them shattering into small pieces.
Maximum temperature
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
Mechanical processing
Machining of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Serious injuries
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
