Pros as well as cons of Nd2Fe14B magnets.
Strengths
- Their magnetic field remains stable, and after around 10 years it drops only by ~1% (theoretically),
- They are extremely resistant to demagnetization induced by external field influence,
- The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which increases force concentration,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to modularity in designing and the capacity to modify to complex applications,
- Key role in innovative solutions – they serve a role in computer drives, motor assemblies, diagnostic systems, also modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- Neodymium magnets decrease their force 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 recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in producing threads and complex shapes in magnets, we recommend using cover - magnetic mount.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a sheet made of mild steel, functioning as a circuit closing element
- with a cross-section minimum 10 mm
- characterized by lack of roughness
- with direct contact (no coatings)
- during detachment in a direction vertical to the plane
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Distance (between the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
- Angle of force application – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin steel does not close the flux, causing part of the flux to be escaped into the air.
- Steel type – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
- Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity was assessed using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Safe handling of NdFeB magnets
Cards and drives
Do not bring magnets close to a purse, computer, or TV. The magnetism can destroy these devices and erase data from cards.
Protective goggles
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Operating temperature
Watch the temperature. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Serious injuries
Pinching hazard: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Choking Hazard
Strictly keep magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are life-threatening.
Handling rules
Use magnets with awareness. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their power.
Medical interference
For implant holders: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Mechanical processing
Combustion risk: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Sensitization to coating
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease working with magnets and use protective gear.
Threat to navigation
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
