Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They have constant strength, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets perfectly defend themselves against loss of magnetization caused by external fields,
- In other words, due to the shiny finish of silver, the element is aesthetically pleasing,
- Neodymium magnets deliver maximum magnetic induction on a their surface, which increases force concentration,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to freedom in forming and the ability to modify to unusual requirements,
- Significant place in modern technologies – they are commonly used in computer drives, brushless drives, diagnostic systems, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in miniature devices
Limitations
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose 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 durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We suggest cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Additionally, small components of these magnets can be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section no less than 10 mm
- with a surface perfectly flat
- with zero gap (no paint)
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Distance (between the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
- Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Danger to pacemakers
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
GPS and phone interference
A powerful magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to prevent breaking the sensors.
Fire risk
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Permanent damage
Watch the temperature. Heating the magnet to high heat will ruin its properties and pulling force.
Finger safety
Large magnets can smash fingers instantly. Never put your hand between two attracting surfaces.
Data carriers
Intense magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Material brittleness
Neodymium magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them shattering into shards.
Nickel coating and allergies
It is widely known that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, refrain from direct skin contact and select encased magnets.
Respect the power
Handle with care. Neodymium magnets act from a distance and snap with huge force, often quicker than you can move away.
Swallowing risk
Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Store out of reach of kids and pets.
