Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- Their magnetic field remains stable, and after approximately ten years it decreases only by ~1% (according to research),
- They show high resistance to demagnetization induced by external disturbances,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
- Thanks to freedom in designing and the ability to customize to complex applications,
- Universal use in modern industrial fields – they are utilized in HDD drives, drive modules, diagnostic systems, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also increases 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 power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price exceeds standard values,
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- using a plate made of mild steel, acting as a ideal flux conductor
- whose thickness is min. 10 mm
- characterized by even structure
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at temperature room level
Lifting capacity in real conditions – factors
- Air gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Alloy admixtures lower magnetic properties and lifting capacity.
- Surface structure – the more even the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Safety rules for work with NdFeB magnets
Operating temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Adults only
Always store magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are tragic.
GPS Danger
GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Do not drill into magnets
Dust created during cutting of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Hand protection
Big blocks can smash fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Data carriers
Very strong magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Sensitization to coating
Certain individuals have a sensitization to nickel, which is the typical protective layer for neodymium magnets. Frequent touching may cause skin redness. It is best to wear safety gloves.
Do not underestimate power
Handle with care. Neodymium magnets act from a distance and connect with huge force, often faster than you can react.
Magnets are brittle
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Health Danger
People with a ICD have to keep an large gap from magnets. The magnetic field can disrupt the operation of the implant.
