Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even after approximately 10 years – the drop in power is only ~1% (theoretically),
- Neodymium magnets are characterized by remarkably resistant to magnetic field loss caused by external interference,
- By using a smooth coating of gold, the element has an aesthetic look,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
- Possibility of accurate modeling and optimizing to concrete applications,
- Significant place in high-tech industry – they are used in magnetic memories, electric drive systems, precision medical tools, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- They are prone to damage upon heavy 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
- Neodymium magnets decrease their force 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 stability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complex forms in magnets, we propose using a housing - magnetic mount.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- with a thickness of at least 10 mm
- with a surface perfectly flat
- with total lack of distance (no coatings)
- under axial force vector (90-degree angle)
- in stable room temperature
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Bodily injuries
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Keep away from computers
Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).
Combustion hazard
Machining of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Medical implants
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Do not overheat magnets
Do not overheat. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Metal Allergy
Studies show that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands or opt for coated magnets.
Precision electronics
Remember: rare earth magnets generate a field that interferes with precision electronics. Keep a safe distance from your phone, device, and GPS.
Keep away from children
Adult use only. Tiny parts pose a choking risk, causing severe trauma. Store away from children and animals.
Caution required
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Magnets are brittle
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
