Advantages as well as disadvantages of rare earth magnets.
Benefits
- They retain magnetic properties for nearly ten years – the loss is just ~1% (based on simulations),
- Neodymium magnets prove to be highly resistant to loss of magnetic properties caused by external interference,
- By applying a smooth coating of gold, the element gains an aesthetic look,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
- Considering the possibility of accurate shaping and adaptation to unique projects, magnetic components can be created in a broad palette of shapes and sizes, which expands the range of possible applications,
- Significant place in electronics industry – they find application in data components, electric motors, diagnostic systems, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small components of these products are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- using a sheet made of low-carbon steel, serving as a ideal flux conductor
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface free of scratches
- under conditions of no distance (surface-to-surface)
- under perpendicular force direction (90-degree angle)
- in stable room temperature
Magnet lifting force in use – key factors
- Clearance – the presence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be wasted into the air.
- Plate material – mild steel attracts best. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Temperature – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.
Safe handling of NdFeB magnets
Bone fractures
Large magnets can smash fingers instantly. Do not place your hand betwixt two strong magnets.
ICD Warning
Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Mechanical processing
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Phone sensors
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, tablet, and GPS.
Danger to the youngest
Only for adults. Small elements can be swallowed, leading to serious injuries. Store away from kids and pets.
Handling guide
Handle with care. Rare earth magnets act from a distance and snap with huge force, often quicker than you can move away.
Keep away from computers
Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
Avoid contact if allergic
Studies show that nickel (the usual finish) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands or select versions in plastic housing.
Thermal limits
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Beware of splinters
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them shattering into shards.
