Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are characterized by exceptionally resistant to loss of magnetic properties caused by external magnetic fields,
- A magnet with a smooth nickel surface has an effective appearance,
- Magnets are distinguished by very high magnetic induction on the outer layer,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Possibility of individual creating as well as optimizing to complex conditions,
- Fundamental importance in advanced technology sectors – they serve a role in computer drives, electric drive systems, advanced medical instruments, also technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We suggest cover - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these devices can be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
- whose thickness reaches at least 10 mm
- characterized by lack of roughness
- with zero gap (without paint)
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance – the presence of any layer (paint, tape, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.
Warnings
Keep away from children
Absolutely store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are tragic.
Physical harm
Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
ICD Warning
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Dust is flammable
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Demagnetization risk
Avoid heat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Keep away from computers
Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Avoid contact if allergic
Certain individuals suffer from a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in an allergic reaction. It is best to wear safety gloves.
Magnetic interference
Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Powerful field
Be careful. Neodymium magnets act from a distance and connect with huge force, often quicker than you can move away.
Fragile material
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
