Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They retain attractive force for almost 10 years – the drop is just ~1% (in theory),
- Magnets effectively protect themselves against loss of magnetization caused by external fields,
- A magnet with a metallic silver surface looks better,
- Neodymium magnets generate maximum magnetic induction on a contact point, which increases force concentration,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the ability of flexible shaping and customization to specialized solutions, NdFeB magnets can be manufactured in a variety of forms and dimensions, which amplifies use scope,
- Significant place in advanced technology sectors – they are commonly used in HDD drives, electric drive systems, diagnostic systems, and modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing nuts and complex shapes in magnets, we propose using cover - magnetic mount.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- with the application of a yoke made of special test steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- under vertical force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Protect data
Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Medical implants
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Magnetic interference
Remember: neodymium magnets produce a field that confuses precision electronics. Keep a separation from your mobile, tablet, and navigation systems.
Serious injuries
Mind your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!
Machining danger
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Adults only
Always store magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are very dangerous.
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop working with magnets and wear gloves.
Protective goggles
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Caution required
Handle magnets with awareness. Their huge power can shock even experienced users. Stay alert and do not underestimate their power.
Demagnetization risk
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
