Pros as well as cons of Nd2Fe14B magnets.
Advantages
- Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- Magnets effectively protect themselves against loss of magnetization caused by ambient magnetic noise,
- A magnet with a shiny silver surface has better aesthetics,
- 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 functioning at temperatures reaching 230°C and above...
- Thanks to freedom in shaping and the ability to adapt to client solutions,
- Key role in electronics industry – they are commonly used in computer drives, motor assemblies, advanced medical instruments, also other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 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 resistant to moisture, when using outdoors
- Limited possibility of producing nuts in the magnet and complex shapes - recommended is cover - magnet mounting.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these products can be problematic in diagnostics 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
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- using a sheet made of mild steel, acting as a magnetic yoke
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- under vertical force vector (90-degree angle)
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Clearance – the presence of any layer (rust, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Material type – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal weaken the grip.
- Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.
H&S for magnets
Skin irritation risks
Certain individuals experience a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in skin redness. We strongly advise use protective gloves.
Compass and GPS
Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Electronic hazard
Avoid bringing magnets near a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Medical implants
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Flammability
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Magnet fragility
Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Handling rules
Be careful. Neodymium magnets attract from a long distance and snap with massive power, often faster than you can move away.
Adults only
Always keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are fatal.
Serious injuries
Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!
Demagnetization risk
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
