Pros as well as cons of rare earth magnets.
Pros
- They do not lose magnetism, even during nearly 10 years – the drop in strength is only ~1% (according to tests),
- They feature excellent resistance to weakening of magnetic properties when exposed to external fields,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which increases force concentration,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- In view of the potential of free forming and customization to individualized projects, magnetic components can be created in a variety of forms and dimensions, which increases their versatility,
- Key role in modern industrial fields – they find application in HDD drives, brushless drives, diagnostic systems, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- 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 complicated shapes in magnets, we recommend using a housing - magnetic mount.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- with the contact of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- characterized by even structure
- without any air gap between the magnet and steel
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Clearance – the presence of any layer (rust, tape, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is reached only during perpendicular pulling. The shear force of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Plate material – low-carbon steel gives the best results. Alloy steels lower magnetic properties and lifting capacity.
- Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Warnings
Magnets are brittle
NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them cracking into small pieces.
Bone fractures
Pinching hazard: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Safe distance
Data protection: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).
Compass and GPS
A powerful magnetic field disrupts the operation of compasses in phones and navigation systems. Do not bring magnets near a smartphone to prevent breaking the sensors.
Avoid contact if allergic
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, cease handling magnets and wear gloves.
This is not a toy
Only for adults. Small elements pose a choking risk, leading to serious injuries. Store away from kids and pets.
Warning for heart patients
Warning for patients: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.
Demagnetization risk
Avoid heat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Do not underestimate power
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Do not drill into magnets
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
