Pros as well as cons of Nd2Fe14B magnets.
Pros
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- Magnets very well resist against demagnetization caused by external fields,
- Thanks to the glossy finish, the layer of nickel, gold-plated, or silver-plated gives an elegant appearance,
- Magnets have exceptionally strong magnetic induction on the active area,
- 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 flexibility in forming and the capacity to modify to client solutions,
- Wide application in advanced technology sectors – they are commonly used in HDD drives, brushless drives, medical devices, and multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize 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 extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in producing nuts and complicated 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 gains importance in the context of child safety. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic field
- whose thickness is min. 10 mm
- with an polished touching surface
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Distance – the presence of any layer (paint, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Temperature – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Operating temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Magnetic media
Do not bring magnets close to a purse, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Do not drill into magnets
Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Caution required
Use magnets with awareness. Their immense force can shock even professionals. Stay alert and respect their force.
Keep away from children
Absolutely keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.
Threat to navigation
Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.
Medical interference
Patients with a ICD should maintain an absolute distance from magnets. The magnetic field can interfere with the functioning of the implant.
Fragile material
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Bone fractures
Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Warning for allergy sufferers
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop working with magnets and wear gloves.
