Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They do not lose strength, even during approximately 10 years – the reduction in strength is only ~1% (based on measurements),
- They possess excellent resistance to magnetic field loss when exposed to external magnetic sources,
- Thanks to the elegant finish, the layer of nickel, gold, or silver-plated gives an clean appearance,
- Magnets possess exceptionally strong magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to versatility in shaping and the capacity to modify to complex applications,
- Versatile presence in innovative solutions – they are commonly used in computer drives, electric motors, medical equipment, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- 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 realizing threads and complicated forms in magnets, we propose using cover - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section of at least 10 mm
- with a surface cleaned and smooth
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Distance – existence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Steel thickness – too thin steel causes magnetic saturation, causing part of the power to be escaped into the air.
- Steel type – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Thermal limits
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Life threat
People with a ICD have to maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Physical harm
Risk of injury: The attraction force is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Mechanical processing
Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Keep away from computers
Equipment safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
No play value
Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Store away from kids and pets.
Conscious usage
Handle magnets consciously. Their immense force can surprise even professionals. Stay alert and do not underestimate their force.
Magnets are brittle
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them cracking into small pieces.
Keep away from electronics
Note: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, device, and GPS.
Sensitization to coating
Certain individuals suffer from a contact allergy to nickel, which is the standard coating for NdFeB magnets. Extended handling might lead to skin redness. We strongly advise wear safety gloves.
