Pros and cons of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even during approximately ten years – the reduction in strength is only ~1% (theoretically),
- They are extremely resistant to demagnetization induced by external disturbances,
- By using a smooth layer of gold, the element presents an aesthetic look,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of accurate creating as well as modifying to specific applications,
- Wide application in future technologies – they find application in magnetic memories, motor assemblies, advanced medical instruments, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions
Disadvantages
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited possibility of producing nuts in the magnet and complex shapes - recommended is cover - magnetic holder.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a base made of high-permeability steel, serving as a magnetic yoke
- whose transverse dimension equals approx. 10 mm
- characterized by smoothness
- under conditions of no distance (surface-to-surface)
- during detachment in a direction vertical to the mounting surface
- at conditions approx. 20°C
Key elements affecting lifting force
- Air gap (betwixt the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or debris).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Swallowing risk
Product intended for adults. Small elements can be swallowed, causing intestinal necrosis. Store away from kids and pets.
Handling guide
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Dust is flammable
Powder produced during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Avoid contact if allergic
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease working with magnets and wear gloves.
ICD Warning
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Eye protection
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
GPS Danger
GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Serious injuries
Big blocks can smash fingers instantly. Do not put your hand between two attracting surfaces.
Magnetic media
Data protection: Strong magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).
Maximum temperature
Do not overheat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
