Other offers
Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They retain attractive force for nearly ten years – the drop is just ~1% (based on simulations),
- They retain their magnetic properties even under strong external field,
- By applying a lustrous coating of gold, the element acquires an aesthetic look,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Considering the ability of flexible forming and customization to specialized needs, NdFeB magnets can be produced in a broad palette of shapes and sizes, which increases their versatility,
- Wide application in modern technologies – they are utilized in data components, electric drive systems, diagnostic systems, and multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- At very 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.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in realizing threads and complex forms in magnets, we propose using cover - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the contact of a sheet made of special test steel, ensuring full magnetic saturation
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an polished contact surface
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance – existence of any layer (rust, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be escaped to the other side.
- Steel type – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Sensitization to coating
Medical facts indicate that nickel (the usual finish) is a common allergen. If you have an allergy, avoid direct skin contact and opt for encased magnets.
Precision electronics
An intense magnetic field interferes with the operation of compasses in phones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.
Serious injuries
Protect your hands. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Be careful!
Shattering risk
NdFeB magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them breaking into small pieces.
Mechanical processing
Powder produced during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Do not underestimate power
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Swallowing risk
Strictly keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are tragic.
Thermal limits
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Threat to electronics
Very strong magnetic fields can destroy records on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Life threat
Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
