Advantages and disadvantages of rare earth magnets.
Pros
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They have excellent resistance to magnetic field loss when exposed to external magnetic sources,
- A magnet with a smooth silver surface has better aesthetics,
- Magnets possess extremely high magnetic induction on the outer side,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to versatility in shaping and the capacity to adapt to specific needs,
- Fundamental importance in future technologies – they are used in computer drives, motor assemblies, diagnostic systems, and modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases 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.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making nuts in the magnet and complex forms - preferred is a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Highest magnetic holding force – what it depends on?
- with the use of a yoke made of special test steel, ensuring full magnetic saturation
- possessing a thickness of at least 10 mm to avoid saturation
- with a plane free of scratches
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at temperature room level
Impact of factors on magnetic holding capacity in practice
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the holding force.
Warnings
Skin irritation risks
Certain individuals suffer from a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact may cause an allergic reaction. It is best to wear safety gloves.
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Demagnetization risk
Do not overheat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Do not give to children
Adult use only. Small elements can be swallowed, leading to severe trauma. Store out of reach of children and animals.
Bodily injuries
Pinching hazard: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Danger to pacemakers
Warning for patients: Powerful magnets affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Protective goggles
Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
Magnetic interference
An intense magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.
Handling guide
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Threat to electronics
Intense magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
