Advantages as well as disadvantages of rare earth magnets.
Advantages
- They have unchanged lifting capacity, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- They maintain their magnetic properties even under strong external field,
- Thanks to the glossy finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an elegant appearance,
- Magnets exhibit exceptionally strong magnetic induction on the outer layer,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Possibility of exact shaping as well as optimizing to specific needs,
- Universal use in electronics industry – they are commonly used in HDD drives, drive modules, precision medical tools, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in small systems
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in strong housings. 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 power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing threads and complex forms in magnets, we recommend using casing - magnetic holder.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Magnetic strength at its maximum – what affects it?
- using a sheet made of high-permeability steel, acting as a magnetic yoke
- with a cross-section of at least 10 mm
- with an ideally smooth touching surface
- with zero gap (without paint)
- during detachment in a direction perpendicular to the mounting surface
- at room temperature
Practical aspects of lifting capacity – factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin steel does not accept the full field, causing part of the flux to be escaped to the other side.
- Plate material – low-carbon steel attracts best. Alloy steels lower magnetic properties and holding force.
- Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Safe handling of NdFeB magnets
Product not for children
Only for adults. Small elements pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.
Avoid contact if allergic
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
Flammability
Combustion risk: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
Serious injuries
Big blocks can break fingers in a fraction of a second. Never put your hand between two attracting surfaces.
Heat sensitivity
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Compass and GPS
Remember: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, device, and navigation systems.
Shattering risk
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Life threat
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Data carriers
Equipment safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
Handling guide
Handle with care. Neodymium magnets act from a distance and connect with massive power, often quicker than you can react.
