Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They do not lose strength, even over around ten years – the drop in power is only ~1% (theoretically),
- Neodymium magnets prove to be extremely resistant to demagnetization caused by external magnetic fields,
- A magnet with a metallic gold surface has better aesthetics,
- Magnetic induction on the working part of the magnet is very high,
- 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 versatility in shaping and the capacity to modify to unusual requirements,
- Wide application in innovative solutions – they find application in computer drives, electric motors, diagnostic systems, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in miniature devices
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We suggest casing - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these devices can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- with an polished contact surface
- under conditions of no distance (surface-to-surface)
- during detachment in a direction vertical to the plane
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Material type – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering 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, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Warning for heart patients
For implant holders: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Impact on smartphones
Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Thermal limits
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Pinching danger
Large magnets can crush fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.
Nickel allergy
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, prevent direct skin contact or opt for versions in plastic housing.
Dust is flammable
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Caution required
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
This is not a toy
Strictly store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are tragic.
Data carriers
Avoid bringing magnets near a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Risk of cracking
Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
