Pros and cons of rare earth magnets.
Benefits
- They retain attractive force for around ten years – the loss is just ~1% (according to analyses),
- They do not lose their magnetic properties even under external field action,
- Thanks to the reflective finish, the coating of nickel, gold-plated, or silver gives an visually attractive appearance,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the potential of flexible forming and adaptation to specialized needs, NdFeB magnets can be modeled in a broad palette of forms and dimensions, which expands the range of possible applications,
- Key role in electronics industry – they serve a role in computer drives, electric drive systems, diagnostic systems, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in small systems
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, 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 strength 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 corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic holder, due to difficulties in producing threads inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small elements of these devices can complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section minimum 10 mm
- with an ground touching surface
- without any insulating layer between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- in stable room temperature
Lifting capacity in practice – influencing factors
- Clearance – existence of any layer (paint, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Shattering risk
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
ICD Warning
For implant holders: Powerful magnets affect electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Magnetic media
Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Keep away from electronics
Note: neodymium magnets generate a field that confuses sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
Permanent damage
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.
Pinching danger
Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
No play value
Neodymium magnets are not toys. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
Safe operation
Exercise caution. Rare earth magnets attract from a distance and snap with massive power, often faster than you can react.
Nickel allergy
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
Machining danger
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
