Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They retain full power for nearly ten years – the drop is just ~1% (based on simulations),
- Neodymium magnets are characterized by remarkably resistant to magnetic field loss caused by external interference,
- Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold, or silver gives an visually attractive appearance,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in shaping and the ability to adapt to specific needs,
- Key role in electronics industry – they are commonly used in mass storage devices, brushless drives, precision medical tools, also other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- 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.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 very resistant to heat
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complex forms - recommended is casing - magnetic holder.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that small elements of these devices are able to be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- with a thickness minimum 10 mm
- with an polished contact surface
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Clearance – existence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Steel type – mild steel gives the best results. Alloy admixtures reduce magnetic properties and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Electronic devices
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Demagnetization risk
Avoid heat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Mechanical processing
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
GPS Danger
A powerful magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.
Implant safety
Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Crushing risk
Big blocks can crush fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.
Warning for allergy sufferers
A percentage of the population have a contact allergy to nickel, which is the standard coating for neodymium magnets. Frequent touching can result in a rash. We strongly advise use protective gloves.
Eye protection
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Powerful field
Handle magnets consciously. Their huge power can shock even professionals. Stay alert and do not underestimate their power.
Danger to the youngest
These products are not intended for children. Swallowing multiple magnets may result in them attracting across intestines, which poses a direct threat to life and requires urgent medical intervention.
