Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- Magnets perfectly defend themselves against loss of magnetization caused by foreign field sources,
- A magnet with a smooth silver surface has an effective appearance,
- Magnetic induction on the working part of the magnet turns out to be exceptional,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Possibility of exact shaping and adjusting to individual requirements,
- Fundamental importance in high-tech industry – they are commonly used in HDD drives, drive modules, medical equipment, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and 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
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complex forms in magnets, we recommend using a housing - magnetic mechanism.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child health protection. Additionally, small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- with a thickness of at least 10 mm
- with an ground touching surface
- under conditions of gap-free contact (metal-to-metal)
- under perpendicular application of breakaway force (90-degree angle)
- at standard ambient temperature
Impact of factors on magnetic holding capacity in practice
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped into the air.
- Plate material – mild steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Flammability
Machining of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
GPS Danger
Remember: rare earth magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.
Do not give to children
Neodymium magnets are not intended for children. Eating multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
Magnets are brittle
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease working with magnets and wear gloves.
Pacemakers
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Handling guide
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Pinching danger
Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, crushing everything in their path. Be careful!
Safe distance
Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.
Heat warning
Keep cool. Neodymium magnets are sensitive to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
