Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- Their strength is maintained, and after around ten years it decreases only by ~1% (theoretically),
- They retain their magnetic properties even under external field action,
- The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They feature high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in shaping and the ability to modify to client solutions,
- Universal use in high-tech industry – they are commonly used in data components, electric motors, medical equipment, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding 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 immune to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complicated shapes in magnets, we propose using cover - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, small components of these magnets are able to 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 can limit application in large quantities
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a block made of mild steel, effectively closing the magnetic field
- possessing a thickness of minimum 10 mm to avoid saturation
- characterized by lack of roughness
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Key elements affecting lifting force
- Clearance – existence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 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 plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and 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.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet and the plate lowers the holding force.
H&S for magnets
Heat warning
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
This is not a toy
Adult use only. Tiny parts can be swallowed, leading to serious injuries. Store out of reach of children and animals.
Nickel coating and allergies
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, cease working with magnets and use protective gear.
Bone fractures
Big blocks can smash fingers instantly. Under no circumstances place your hand between two strong magnets.
Protect data
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Threat to navigation
Be aware: rare earth magnets generate a field that disrupts precision electronics. Keep a safe distance from your mobile, tablet, and GPS.
Machining danger
Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Implant safety
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Eye protection
Watch out for shards. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.
Respect the power
Handle magnets consciously. Their immense force can shock even professionals. Stay alert and do not underestimate their force.
