Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- Their magnetic field is durable, and after around ten years it drops only by ~1% (theoretically),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by external interference,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working part of the magnet turns out to be maximum,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in forming and the ability to modify to complex applications,
- Key role in modern technologies – they are commonly used in computer drives, brushless drives, medical devices, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices
Cons
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We suggest cover - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex shapes.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these products are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what affects it?
- on a block made of structural steel, optimally conducting the magnetic flux
- possessing a massiveness of at least 10 mm to avoid saturation
- with an polished touching surface
- without the slightest clearance between the magnet and steel
- during pulling in a direction perpendicular to the plane
- in neutral thermal conditions
Key elements affecting lifting force
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Stainless steels may attract less.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Heat sensitivity
Watch the temperature. Heating the magnet to high heat will ruin its magnetic structure and pulling force.
Implant safety
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Electronic devices
Device Safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, hearing aids, timepieces).
Adults only
Product intended for adults. Small elements can be swallowed, causing severe trauma. Keep out of reach of kids and pets.
Allergy Warning
Studies show that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from direct skin contact and choose coated magnets.
Phone sensors
A powerful magnetic field negatively affects the operation of compasses in phones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Pinching danger
Large magnets can break fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.
Combustion hazard
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Immense force
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Material brittleness
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
