Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even after around ten years – the drop in lifting capacity is only ~1% (based on measurements),
- Magnets very well protect themselves against loss of magnetization caused by ambient magnetic noise,
- By covering with a lustrous coating of gold, the element acquires an professional look,
- Magnetic induction on the top side of the magnet is maximum,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- In view of the potential of free shaping and adaptation to specialized projects, magnetic components can be produced in a variety of forms and dimensions, which increases their versatility,
- Universal use in electronics industry – they are commonly used in hard drives, drive modules, medical equipment, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in miniature devices
Cons
- At 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.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We recommend a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, small elements of these products 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 increases costs of application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- with the application of a yoke made of special test steel, ensuring full magnetic saturation
- whose transverse dimension is min. 10 mm
- with a surface perfectly flat
- without the slightest clearance between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Clearance – the presence of foreign body (paint, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal 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 type – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Combustion hazard
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Warning for allergy sufferers
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.
Do not underestimate power
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Threat to electronics
Data protection: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).
Operating temperature
Monitor thermal conditions. Exposing the magnet to high heat will destroy its properties and pulling force.
Danger to pacemakers
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Keep away from children
Strictly store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are very dangerous.
Fragile material
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Crushing force
Protect your hands. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Impact on smartphones
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
