Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They do not lose strength, even over approximately ten years – the reduction in power is only ~1% (based on measurements),
- Neodymium magnets prove to be extremely resistant to loss of magnetic properties caused by external field sources,
- By covering with a smooth layer of gold, the element has an modern look,
- Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of accurate shaping and modifying to individual needs,
- Huge importance in electronics industry – they are used in hard drives, motor assemblies, medical equipment, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing nuts in the magnet and complex forms - preferred is a housing - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small components of these magnets can be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a base made of mild steel, functioning as a circuit closing element
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by lack of roughness
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at temperature room level
Determinants of practical lifting force of a magnet
- Air gap (between the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Permanent damage
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Caution required
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Dust explosion hazard
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
ICD Warning
Individuals with a ICD have to maintain an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
Impact on smartphones
A strong magnetic field interferes with the functioning of compasses in phones and navigation systems. Do not bring magnets near a device to avoid damaging the sensors.
Sensitization to coating
Studies show that nickel (the usual finish) is a potent allergen. For allergy sufferers, refrain from direct skin contact and select encased magnets.
Safe distance
Intense magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.
Shattering risk
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Bone fractures
Big blocks can crush fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
Product not for children
Absolutely store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are very dangerous.
