Strengths and weaknesses of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under close interference source,
- A magnet with a smooth gold surface is more attractive,
- Magnets are characterized by maximum magnetic induction on the outer layer,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in forming and the ability to adapt to unusual requirements,
- Huge importance in electronics industry – they find application in computer drives, brushless drives, diagnostic systems, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating threads in the magnet and complicated forms - recommended is a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these magnets can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- on a plate made of structural steel, effectively closing the magnetic field
- with a cross-section of at least 10 mm
- characterized by even structure
- without any air gap between the magnet and steel
- during detachment in a direction vertical to the plane
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Distance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, 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 load capacity.
Safe handling of NdFeB magnets
Dust explosion hazard
Fire hazard: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Threat to navigation
A powerful magnetic field disrupts the operation of compasses in phones and navigation systems. Keep magnets near a smartphone to prevent breaking the sensors.
Warning for allergy sufferers
It is widely known that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands and select encased magnets.
Pacemakers
Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Protective goggles
Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Serious injuries
Large magnets can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
Do not give to children
Strictly store magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are life-threatening.
Threat to electronics
Do not bring magnets close to a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Heat warning
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Safe operation
Use magnets with awareness. Their powerful strength can shock even experienced users. Plan your moves and do not underestimate their force.
