Pros and cons of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even over approximately 10 years – the drop in strength is only ~1% (theoretically),
- Magnets perfectly resist against loss of magnetization caused by external fields,
- A magnet with a metallic gold surface looks better,
- Magnetic induction on the top side of the magnet remains extremely intense,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Considering the potential of flexible forming and adaptation to unique needs, NdFeB magnets can be created in a broad palette of geometric configurations, which amplifies use scope,
- Wide application in future technologies – they are commonly used in magnetic memories, motor assemblies, diagnostic systems, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in miniature devices
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend 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 - mounting mechanism.
- Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical when they are in the body.
- 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
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- using a plate made of high-permeability steel, functioning as a circuit closing element
- whose transverse dimension is min. 10 mm
- with a plane cleaned and smooth
- with direct contact (no coatings)
- under axial application of breakaway force (90-degree angle)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Distance (betwixt the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Immense force
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Fragile material
Neodymium magnets are sintered ceramics, which means they are very brittle. Impact of two magnets will cause them breaking into small pieces.
Skin irritation risks
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease working with magnets and wear gloves.
Precision electronics
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.
Swallowing risk
NdFeB magnets are not suitable for play. Accidental ingestion of several magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
Fire warning
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Cards and drives
Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
Health Danger
Warning for patients: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or ask another person to work with the magnets.
Finger safety
Risk of injury: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Heat warning
Avoid heat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
