Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets very well protect themselves against demagnetization caused by ambient magnetic noise,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets have very high magnetic induction on the outer layer,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of detailed modeling as well as optimizing to specific conditions,
- Fundamental importance in modern technologies – they are utilized in computer drives, electric motors, medical equipment, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as 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 immune to moisture, in case of application outdoors
- Due to limitations in producing threads and complicated forms in magnets, we recommend using a housing - magnetic mount.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small elements of these devices can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- using a sheet made of high-permeability steel, acting as a ideal flux conductor
- whose thickness is min. 10 mm
- with a plane free of scratches
- without any air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Temperature – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Data carriers
Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Conscious usage
Be careful. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.
Magnets are brittle
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Physical harm
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.
Flammability
Dust created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Demagnetization risk
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Danger to the youngest
Only for adults. Tiny parts pose a choking risk, leading to serious injuries. Keep away from kids and pets.
Keep away from electronics
A powerful magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a device to prevent damaging the sensors.
ICD Warning
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
