Pros and cons of neodymium magnets.
Strengths
- Their strength is maintained, and after around ten years it decreases only by ~1% (according to research),
- They feature excellent resistance to magnetic field loss as a result of external magnetic sources,
- A magnet with a shiny silver surface has an effective appearance,
- Magnetic induction on the working part of the magnet remains impressive,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to modularity in shaping and the ability to adapt to complex applications,
- Key role in electronics industry – they are used in magnetic memories, electric drive systems, advanced medical instruments, and complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making nuts in the magnet and complex shapes - preferred is casing - magnet mounting.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by smoothness
- with zero gap (without coatings)
- during detachment in a direction vertical to the plane
- at room temperature
What influences lifting capacity in practice
- Space between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Danger to the youngest
NdFeB magnets are not toys. Swallowing multiple magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and requires immediate surgery.
Pacemakers
Individuals with a heart stimulator have to keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the implant.
Warning for allergy sufferers
Certain individuals have a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching may cause a rash. We suggest wear protective gloves.
Powerful field
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Bone fractures
Big blocks can smash fingers instantly. Never put your hand betwixt two attracting surfaces.
Fragile material
Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Precision electronics
Be aware: rare earth magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, device, and GPS.
Demagnetization risk
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.
Data carriers
Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Mechanical processing
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
