Advantages as well as disadvantages of rare earth magnets.
Strengths
- They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They have excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
- A magnet with a metallic gold surface is more attractive,
- Magnetic induction on the working part of the magnet remains impressive,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to versatility in designing and the ability to customize to client solutions,
- Fundamental importance in modern technologies – they serve a role in mass storage devices, electromotive mechanisms, precision medical tools, also industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets demagnetize 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 extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using cover - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small components of these magnets can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Highest magnetic holding force – what it depends on?
- with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
- with a thickness no less than 10 mm
- with a surface free of scratches
- with total lack of distance (no coatings)
- under axial application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Distance – existence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.
Warnings
Phone sensors
Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Respect the power
Handle magnets with awareness. Their immense force can shock even experienced users. Plan your moves and do not underestimate their power.
Adults only
Neodymium magnets are not suitable for play. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and necessitates immediate surgery.
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, avoid touching magnets with bare hands or select coated magnets.
Crushing force
Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!
Medical interference
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Cards and drives
Do not bring magnets near a purse, computer, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.
Fragile material
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Fire risk
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Maximum temperature
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
