Pros as well as cons of Nd2Fe14B magnets.
Benefits
- Their power remains stable, and after approximately 10 years it drops only by ~1% (according to research),
- They are noted for resistance to demagnetization induced by external field influence,
- A magnet with a metallic gold surface is more attractive,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- 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...
- Due to the possibility of accurate forming and adaptation to specialized projects, NdFeB magnets can be created in a variety of forms and dimensions, which increases their versatility,
- Key role in electronics industry – they find application in hard drives, electric motors, advanced medical instruments, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating threads in the magnet and complicated forms - recommended is casing - magnet mounting.
- Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small components of these products can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Highest magnetic holding force – what it depends on?
- using a sheet made of mild steel, serving as a circuit closing element
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- under conditions of ideal adhesion (surface-to-surface)
- under axial force vector (90-degree angle)
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet and the plate lowers the load capacity.
Safe handling of neodymium magnets
Physical harm
Risk of injury: The pulling power is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Conscious usage
Be careful. Rare earth magnets act from a long distance and connect with massive power, often faster than you can move away.
Maximum temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Risk of cracking
NdFeB magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them breaking into shards.
Medical interference
For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Cards and drives
Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
Fire warning
Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
Threat to navigation
Remember: rare earth magnets produce a field that disrupts precision electronics. Maintain a safe distance from your phone, tablet, and GPS.
Swallowing risk
NdFeB magnets are not intended for children. Swallowing multiple magnets can lead to them attracting across intestines, which constitutes a direct threat to life and necessitates immediate surgery.
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop handling magnets and wear gloves.
