Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even after approximately 10 years – the drop in power is only ~1% (according to tests),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- A magnet with a shiny silver surface has an effective appearance,
- Magnets exhibit huge magnetic induction on the active area,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Possibility of detailed modeling as well as adapting to defined needs,
- Versatile presence in modern industrial fields – they serve a role in hard drives, motor assemblies, medical equipment, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in small systems
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complex forms in magnets, we propose using cover - magnetic mount.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these devices can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what affects it?
- on a block made of mild steel, optimally conducting the magnetic field
- with a thickness no less than 10 mm
- with an ideally smooth contact surface
- with total lack of distance (no paint)
- during detachment in a direction perpendicular to the plane
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or dirt).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
- Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Demagnetization risk
Control the heat. Exposing the magnet to high heat will ruin its properties and strength.
Warning for heart patients
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Threat to navigation
GPS units and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Avoid contact if allergic
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease working with magnets and use protective gear.
Magnet fragility
Watch out for shards. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.
Threat to electronics
Do not bring magnets near a wallet, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
Combustion hazard
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Caution required
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Choking Hazard
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Keep away from children and animals.
Bodily injuries
Large magnets can break fingers instantly. Do not place your hand between two strong magnets.
