Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They retain full power for nearly ten years – the drop is just ~1% (according to analyses),
- Magnets effectively defend themselves against loss of magnetization caused by ambient magnetic noise,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets exhibit huge magnetic induction on the outer side,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
- Thanks to versatility in designing and the ability to customize to specific needs,
- Fundamental importance in advanced technology sectors – they are utilized in computer drives, electric motors, advanced medical instruments, as well as technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 very resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a block made of mild steel, perfectly concentrating the magnetic field
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by even structure
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Key elements affecting lifting force
- Distance (between the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Direction of force – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Safe handling of NdFeB magnets
Beware of splinters
NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them shattering into shards.
Dust is flammable
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Safe operation
Handle magnets consciously. Their powerful strength can shock even experienced users. Be vigilant and do not underestimate their force.
Crushing risk
Big blocks can break fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Choking Hazard
NdFeB magnets are not suitable for play. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates immediate surgery.
Health Danger
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Compass and GPS
A strong magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Keep magnets close to a device to prevent breaking the sensors.
Do not overheat magnets
Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Safe distance
Avoid bringing magnets near a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Nickel allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, immediately stop handling magnets and wear gloves.
