Advantages and disadvantages of neodymium magnets.
Strengths
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
- They do not lose their magnetic properties even under external field action,
- In other words, due to the metallic surface of silver, the element gains a professional look,
- Magnetic induction on the top side of the magnet is extremely intense,
- 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...
- Thanks to the possibility of flexible forming and adaptation to unique requirements, neodymium magnets can be created in a variety of forms and dimensions, which amplifies use scope,
- Significant place in modern industrial fields – they are utilized in data components, drive modules, precision medical tools, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complex shapes in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small elements of these products can 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
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a sheet made of high-permeability steel, functioning as a magnetic yoke
- with a thickness no less than 10 mm
- with a surface perfectly flat
- under conditions of ideal adhesion (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Metal type – different alloys reacts the same. High carbon content worsen the attraction effect.
- Surface finish – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
- 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, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Power loss in heat
Keep cool. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Skin irritation risks
Certain individuals have a sensitization to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to dermatitis. We suggest use protective gloves.
Powerful field
Exercise caution. Rare earth magnets act from a distance and snap with huge force, often faster than you can react.
Health Danger
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Protective goggles
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Magnetic interference
Remember: rare earth magnets generate a field that disrupts precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
Serious injuries
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Protect data
Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Keep away from children
Strictly store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are life-threatening.
Dust is flammable
Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
