Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They do not lose strength, even during around ten years – the drop in power is only ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external disturbances,
- In other words, due to the metallic surface of gold, the element looks attractive,
- Magnetic induction on the surface of the magnet turns out to be exceptional,
- 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...
- Thanks to freedom in shaping and the ability to modify to individual projects,
- Huge importance in electronics industry – they are utilized in HDD drives, drive modules, precision medical tools, also complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- At strong impacts they can break, therefore we recommend 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 immune to moisture, when using outdoors
- We recommend cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these devices can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose thickness reaches at least 10 mm
- with a plane perfectly flat
- with direct contact (without coatings)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Distance – the presence of foreign body (rust, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Warnings
Avoid contact if allergic
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.
Implant safety
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Operating temperature
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.
Bodily injuries
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Safe distance
Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.
Powerful field
Handle with care. Rare earth magnets attract from a distance and snap with massive power, often faster than you can move away.
Phone sensors
GPS units and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Shattering risk
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Flammability
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
No play value
Absolutely keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are very dangerous.
