Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for around 10 years – the loss is just ~1% (according to analyses),
- They have excellent resistance to weakening of magnetic properties as a result of external fields,
- Thanks to the metallic finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
- Neodymium magnets achieve maximum magnetic induction on a small area, which allows for strong attraction,
- 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 modularity in forming and the capacity to adapt to individual projects,
- Universal use in electronics industry – they find application in computer drives, electromotive mechanisms, diagnostic systems, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in compact constructions
Weaknesses
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using a housing - magnetic mount.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Highest magnetic holding force – what it depends on?
- using a sheet made of mild steel, acting as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- with a plane free of scratches
- without the slightest air gap between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Base massiveness – too thin sheet does not accept the full field, causing part of the power to be lost into the air.
- Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Keep away from electronics
A strong magnetic field interferes with the operation of compasses in phones and GPS navigation. Maintain magnets near a device to prevent breaking the sensors.
No play value
Only for adults. Tiny parts can be swallowed, causing severe trauma. Store away from children and animals.
Thermal limits
Watch the temperature. Exposing the magnet to high heat will permanently weaken its magnetic structure and pulling force.
ICD Warning
Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.
Data carriers
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, medical aids, timepieces).
Handling guide
Handle with care. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can react.
Serious injuries
Large magnets can break fingers in a fraction of a second. Never put your hand between two attracting surfaces.
Skin irritation risks
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Material brittleness
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Flammability
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
