Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They do not lose strength, even during around 10 years – the reduction in lifting capacity is only ~1% (according to tests),
- They feature excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- Thanks to the glossy finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an clean appearance,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Thanks to flexibility in constructing and the ability to adapt to unusual requirements,
- Universal use in modern industrial fields – they are utilized in mass storage devices, electric motors, medical devices, as well as multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their power 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complex forms - recommended is casing - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small components of these products are able to be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a base made of mild steel, perfectly concentrating the magnetic field
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- with zero gap (no coatings)
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Air gap (betwixt the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Direction of force – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Keep away from electronics
Note: rare earth magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.
Bodily injuries
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Handling guide
Use magnets consciously. Their immense force can shock even experienced users. Stay alert and respect their power.
Medical implants
Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
No play value
NdFeB magnets are not toys. Eating a few magnets may result in them pinching intestinal walls, which constitutes a critical condition and requires immediate surgery.
Heat sensitivity
Standard neodymium magnets (grade N) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Data carriers
Intense magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Dust explosion hazard
Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Nickel coating and allergies
It is widely known that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands and choose encased magnets.
Risk of cracking
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
