Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They do not lose strength, even during around 10 years – the drop in strength is only ~1% (based on measurements),
- They show high resistance to demagnetization induced by external magnetic fields,
- Thanks to the glossy finish, the surface of nickel, gold, or silver-plated gives an clean appearance,
- Magnetic induction on the surface of the magnet turns out to be impressive,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
- In view of the possibility of accurate forming and customization to specialized projects, neodymium magnets can be modeled in a variety of geometric configurations, which increases their versatility,
- Universal use in electronics industry – they are utilized in mass storage devices, electromotive mechanisms, diagnostic systems, as well as complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their force 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 corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, tiny parts of these devices 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 affects it?
- on a plate made of mild steel, optimally conducting the magnetic flux
- with a cross-section minimum 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped to the other side.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate decreases the holding force.
Safe handling of neodymium magnets
Danger to the youngest
Only for adults. Tiny parts can be swallowed, causing severe trauma. Store out of reach of children and animals.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.
Electronic hazard
Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
Handling rules
Exercise caution. Neodymium magnets act from a distance and connect with huge force, often quicker than you can react.
Health Danger
For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Maximum temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Machining danger
Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Phone sensors
GPS units and smartphones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Shattering risk
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Finger safety
Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
