Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They retain magnetic properties for around ten years – the loss is just ~1% (based on simulations),
- They maintain their magnetic properties even under external field action,
- A magnet with a shiny nickel surface has better aesthetics,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of accurate machining as well as optimizing to atypical applications,
- Huge importance in electronics industry – they are used in computer drives, electric drive systems, diagnostic systems, also multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing nuts in the magnet and complex forms - preferred is casing - mounting mechanism.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Highest magnetic holding force – what contributes to it?
- with the use of a sheet made of special test steel, ensuring full magnetic saturation
- with a cross-section minimum 10 mm
- with an polished contact surface
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction vertical to the plane
- in temp. approx. 20°C
Determinants of lifting force in real conditions
- Gap (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Metal type – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Base smoothness – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Precision electronics
Note: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, device, and navigation systems.
Heat warning
Avoid heat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Skin irritation risks
A percentage of the population experience a contact allergy to nickel, which is the common plating for neodymium magnets. Prolonged contact might lead to a rash. We strongly advise use protective gloves.
Crushing force
Danger of trauma: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Life threat
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Magnetic media
Do not bring magnets near a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Protective goggles
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them cracking into shards.
Caution required
Exercise caution. Neodymium magnets act from a distance and connect with massive power, often faster than you can move away.
No play value
Product intended for adults. Small elements pose a choking risk, leading to intestinal necrosis. Store out of reach of children and animals.
Fire warning
Powder produced during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
