Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They retain magnetic properties for almost ten years – the loss is just ~1% (according to analyses),
- They are resistant to demagnetization induced by external magnetic fields,
- In other words, due to the metallic finish of silver, the element gains a professional look,
- Magnets have very high magnetic induction on the working surface,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Possibility of custom forming and optimizing to defined conditions,
- Universal use in advanced technology sectors – they are utilized in hard drives, brushless drives, medical equipment, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these products can complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic flux
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a surface perfectly flat
- without any clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Plate material – low-carbon steel gives the best results. Alloy admixtures lower magnetic permeability and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Handling rules
Be careful. Rare earth magnets act from a long distance and snap with massive power, often faster than you can react.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and strength.
GPS and phone interference
Note: neodymium magnets produce a field that confuses sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Magnet fragility
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Sensitization to coating
Medical facts indicate that nickel (the usual finish) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and opt for versions in plastic housing.
Threat to electronics
Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Physical harm
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, crushing anything in their path. Be careful!
Medical interference
People with a ICD should maintain an large gap from magnets. The magnetic field can interfere with the operation of the implant.
Adults only
NdFeB magnets are not suitable for play. Accidental ingestion of several magnets may result in them attracting across intestines, which constitutes a critical condition and requires immediate surgery.
Dust is flammable
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
