Pros and cons of Nd2Fe14B magnets.
Advantages
- They retain attractive force for almost ten years – the loss is just ~1% (in theory),
- Magnets effectively protect themselves against loss of magnetization caused by external fields,
- In other words, due to the metallic layer of nickel, the element looks attractive,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- In view of the potential of flexible shaping and customization to individualized needs, magnetic components can be produced in a variety of shapes and sizes, which amplifies use scope,
- Significant place in electronics industry – they are used in magnetic memories, drive modules, advanced medical instruments, and multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of producing threads in the magnet and complex forms - recommended is casing - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with a plane free of scratches
- without the slightest air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Air gap (between the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Load vector – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Plate texture – ground elements ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Allergy Warning
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and use protective gear.
Operating temperature
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Caution required
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Safe distance
Intense magnetic fields can destroy records on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.
Medical implants
Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Machining danger
Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
This is not a toy
Product intended for adults. Small elements can be swallowed, causing severe trauma. Keep away from children and animals.
Threat to navigation
Remember: rare earth magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
Risk of cracking
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Bone fractures
Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
