Advantages and disadvantages of rare earth magnets.
Advantages
- They have constant strength, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- They feature excellent resistance to magnetism drop as a result of opposing magnetic fields,
- By using a lustrous coating of gold, the element has an elegant look,
- Magnets possess excellent magnetic induction on the outer layer,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Due to the potential of precise shaping and customization to unique requirements, NdFeB magnets can be manufactured in a broad palette of forms and dimensions, which makes them more universal,
- Key role in innovative solutions – they serve a role in magnetic memories, drive modules, precision medical tools, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are prone to damage 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
- 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. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in producing threads and complicated shapes in magnets, we propose using a housing - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these devices are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of high-permeability steel, functioning as a circuit closing element
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by smoothness
- with zero gap (no coatings)
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick sheet does not close the flux, causing part of the power to be escaped into the air.
- Material composition – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Maximum temperature
Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Sensitization to coating
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease handling magnets and use protective gear.
Handling guide
Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can move away.
Protect data
Data protection: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Serious injuries
Mind your fingers. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Magnetic interference
Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Health Danger
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Do not give to children
Neodymium magnets are not toys. Accidental ingestion of a few magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates urgent medical intervention.
Dust explosion hazard
Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Magnets are brittle
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them breaking into shards.
