Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They retain attractive force for almost ten years – the loss is just ~1% (in theory),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- 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 accurate shaping and adapting to complex needs,
- Versatile presence in modern technologies – they find application in hard drives, motor assemblies, medical equipment, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in miniature devices
Disadvantages
- At very strong impacts they can break, therefore we recommend 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 strength. Often, when the temperature exceeds 80°C, their power 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
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small components of these devices can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what affects it?
- on a plate made of structural steel, effectively closing the magnetic flux
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- with direct contact (without impurities)
- during detachment in a direction vertical to the mounting surface
- at room temperature
Key elements affecting lifting force
- Clearance – the presence of any layer (rust, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Metal type – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Precision electronics
A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Keep magnets close to a smartphone to avoid damaging the sensors.
Electronic hazard
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Adults only
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Store away from children and animals.
Sensitization to coating
A percentage of the population suffer from a sensitization to Ni, which is the standard coating for NdFeB magnets. Prolonged contact can result in a rash. We recommend use protective gloves.
Hand protection
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
Handling guide
Use magnets with awareness. Their huge power can surprise even professionals. Be vigilant and do not underestimate their power.
Warning for heart patients
Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Dust explosion hazard
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Beware of splinters
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Permanent damage
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
