Strengths and weaknesses of rare earth magnets.
Strengths
- They do not lose magnetism, even after around 10 years – the decrease in lifting capacity is only ~1% (theoretically),
- Magnets very well resist against demagnetization caused by external fields,
- By covering with a smooth coating of gold, the element presents an elegant look,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
- Possibility of accurate shaping and optimizing to individual applications,
- Huge importance in electronics industry – they are utilized in HDD drives, motor assemblies, medical equipment, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these devices can complicate diagnosis medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a plate made of low-carbon steel, functioning as a ideal flux conductor
- with a cross-section no less than 10 mm
- with an ground contact surface
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Protect data
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.
Threat to navigation
A strong magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Caution required
Handle with care. Rare earth magnets attract from a long distance and connect with huge force, often faster than you can move away.
Heat warning
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Machining danger
Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Health Danger
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
This is not a toy
Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates immediate surgery.
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop working with magnets and wear gloves.
Protective goggles
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them cracking into small pieces.
Bone fractures
Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Be careful!
