Strengths as well as weaknesses of rare earth magnets.
Benefits
- They have stable power, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They maintain their magnetic properties even under external field action,
- A magnet with a shiny nickel surface is more attractive,
- Magnets have exceptionally strong magnetic induction on the outer side,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in forming and the capacity to customize to individual projects,
- Wide application in electronics industry – they are utilized in HDD drives, motor assemblies, medical devices, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in realizing threads and complicated forms in magnets, we recommend using casing - magnetic mount.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small components of these devices are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to avoid saturation
- characterized by smoothness
- with direct contact (no paint)
- under perpendicular force direction (90-degree angle)
- at ambient temperature room level
Practical aspects of lifting capacity – factors
- Distance – the presence of any layer (rust, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Temperature – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Magnets are brittle
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Skin irritation risks
Some people have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Extended handling may cause an allergic reaction. We strongly advise use protective gloves.
Fire risk
Fire warning: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Health Danger
People with a pacemaker must keep an safe separation from magnets. The magnetic field can stop the operation of the implant.
Compass and GPS
GPS units and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Caution required
Use magnets consciously. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their force.
Bone fractures
Large magnets can smash fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
This is not a toy
Adult use only. Small elements pose a choking risk, leading to serious injuries. Store away from children and animals.
Operating temperature
Keep cool. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Keep away from computers
Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
