Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even during around 10 years – the drop in lifting capacity is only ~1% (based on measurements),
- They maintain their magnetic properties even under strong external field,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets have exceptionally strong magnetic induction on the working surface,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
- Possibility of accurate forming as well as adjusting to defined applications,
- Huge importance in electronics industry – they are commonly used in HDD drives, brushless drives, medical equipment, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, 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 steel housing, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing threads and complex forms in magnets, we recommend using casing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Highest magnetic holding force – what contributes to it?
- using a sheet made of mild steel, serving as a ideal flux conductor
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by smoothness
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Clearance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Wall 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. Alloy admixtures reduce magnetic permeability and holding force.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.
Dust is flammable
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Magnets are brittle
NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets leads to them breaking into shards.
Immense force
Handle with care. Rare earth magnets act from a long distance and connect with huge force, often faster than you can react.
Maximum temperature
Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Allergic reactions
Medical facts indicate that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact or opt for encased magnets.
Threat to navigation
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Hand protection
Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Cards and drives
Very strong magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Medical implants
For implant holders: Powerful magnets affect medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Adults only
Neodymium magnets are not suitable for play. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires urgent medical intervention.
