Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- Magnets perfectly defend themselves against demagnetization caused by ambient magnetic noise,
- Thanks to the elegant finish, the layer of Ni-Cu-Ni, gold, or silver gives an visually attractive appearance,
- Magnetic induction on the working layer of the magnet is impressive,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in designing and the ability to adapt to individual projects,
- Significant place in innovative solutions – they are used in HDD drives, drive modules, advanced medical instruments, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in small systems
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 improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in strength. 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 while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing threads and complex forms in magnets, we recommend using a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- with a thickness of at least 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- during detachment in a direction perpendicular to the mounting surface
- at temperature room level
Magnet lifting force in use – key factors
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.
Warnings
Combustion hazard
Powder generated during machining of magnets is flammable. Do not drill into magnets unless you are an expert.
Avoid contact if allergic
Some people suffer from a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact may cause dermatitis. It is best to wear safety gloves.
Swallowing risk
Adult use only. Tiny parts can be swallowed, leading to serious injuries. Keep out of reach of kids and pets.
Crushing force
Danger of trauma: The pulling power is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Maximum temperature
Avoid heat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Caution required
Handle with care. Neodymium magnets act from a distance and snap with huge force, often quicker than you can react.
Magnet fragility
Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Pacemakers
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Magnetic media
Avoid bringing magnets near a purse, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.
Magnetic interference
An intense magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.
