Pros as well as cons of Nd2Fe14B magnets.
Pros
- They retain attractive force for nearly 10 years – the drop is just ~1% (based on simulations),
- They retain their magnetic properties even under strong external field,
- A magnet with a metallic nickel surface has better aesthetics,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in shaping and the ability to adapt to specific needs,
- Fundamental importance in future technologies – they serve a role in data components, electric drive systems, medical equipment, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in realizing threads and complicated shapes in magnets, we recommend using a housing - magnetic holder.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these magnets are able to be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is higher than average,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- whose thickness reaches at least 10 mm
- with a plane perfectly flat
- without any clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Magnet lifting force in use – key factors
- Distance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin sheet does not close the flux, causing part of the power to be wasted to the other side.
- Steel type – mild steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate lowers the load capacity.
Warnings
Adults only
Absolutely store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are life-threatening.
Magnetic media
Device Safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Crushing risk
Danger of trauma: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Do not drill into magnets
Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
GPS and phone interference
An intense magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to avoid damaging the sensors.
ICD Warning
Individuals with a ICD must keep an absolute distance from magnets. The magnetic field can interfere with the functioning of the implant.
Allergy Warning
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease working with magnets and wear gloves.
Caution required
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Heat warning
Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Shattering risk
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them breaking into shards.
