Pros and cons of Nd2Fe14B magnets.
Pros
- Their magnetic field is maintained, and after approximately ten years it drops only by ~1% (according to research),
- They retain their magnetic properties even under close interference source,
- By applying a decorative layer of nickel, the element has an modern look,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of exact shaping as well as modifying to individual requirements,
- Versatile presence in modern industrial fields – they are used in magnetic memories, motor assemblies, medical equipment, and multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets lose their power 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of producing nuts in the magnet and complex shapes - preferred is cover - mounting mechanism.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these devices are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- on a base made of mild steel, optimally conducting the magnetic flux
- whose transverse dimension equals approx. 10 mm
- with an ground contact surface
- with direct contact (no coatings)
- during detachment in a direction perpendicular to the plane
- in stable room temperature
What influences lifting capacity in practice
- Distance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Warning for heart patients
Patients with a heart stimulator should maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Risk of cracking
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them breaking into shards.
Adults only
Always store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.
Maximum temperature
Keep cool. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Sensitization to coating
Studies show that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands or choose encased magnets.
Fire risk
Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Phone sensors
Remember: neodymium magnets produce a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and navigation systems.
Powerful field
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Cards and drives
Intense magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Pinching danger
Pinching hazard: The attraction force is so immense that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
