Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They feature excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- A magnet with a metallic nickel surface has better aesthetics,
- Magnets have exceptionally strong magnetic induction on the active area,
- 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 custom machining as well as adapting to individual conditions,
- Huge importance in modern technologies – they serve a role in HDD drives, drive modules, advanced medical instruments, and modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's 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, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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, in case of application outdoors
- Due to limitations in producing nuts and complex forms in magnets, we propose using casing - magnetic mount.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these devices can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- with a cross-section minimum 10 mm
- characterized by even structure
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- at room temperature
Determinants of practical lifting force of a magnet
- Air gap (betwixt the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, rust or dirt).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Plate material – mild steel attracts best. Alloy steels decrease magnetic properties and holding force.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Do not underestimate power
Handle magnets consciously. Their immense force can shock even professionals. Stay alert and do not underestimate their force.
Shattering risk
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets will cause them cracking into small pieces.
Pinching danger
Watch your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Keep away from electronics
Remember: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.
Warning for heart patients
Individuals with a ICD should keep an safe separation from magnets. The magnetic field can disrupt the operation of the implant.
Do not drill into magnets
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Thermal limits
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Keep away from children
These products are not intended for children. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and requires urgent medical intervention.
Nickel coating and allergies
It is widely known that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands or select coated magnets.
Magnetic media
Device Safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
