Pros as well as cons of Nd2Fe14B magnets.
Advantages
- Their magnetic field remains stable, and after around 10 years it drops only by ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external field influence,
- A magnet with a shiny silver surface has an effective appearance,
- Neodymium magnets generate maximum magnetic induction on a contact point, which increases force concentration,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of individual forming and optimizing to precise requirements,
- Universal use in modern technologies – they are used in mass storage devices, electromotive mechanisms, medical equipment, also complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making threads in the magnet and complicated shapes - preferred is cover - magnet mounting.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- using a sheet made of mild steel, acting as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- with total lack of distance (without paint)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Data carriers
Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Fire warning
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Bodily injuries
Large magnets can crush fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
ICD Warning
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Demagnetization risk
Monitor thermal conditions. Exposing the magnet to high heat will ruin its properties and pulling force.
Do not give to children
Absolutely store magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are life-threatening.
Allergy Warning
Certain individuals suffer from a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Extended handling may cause an allergic reaction. We suggest use safety gloves.
Magnet fragility
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Caution required
Handle magnets consciously. Their immense force can shock even experienced users. Plan your moves and respect their power.
Impact on smartphones
A powerful magnetic field interferes with the operation of compasses in smartphones and navigation systems. Maintain magnets near a smartphone to prevent breaking the sensors.
