Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even during around 10 years – the reduction in strength is only ~1% (based on measurements),
- Neodymium magnets remain remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
- By applying a lustrous layer of nickel, the element gains an professional look,
- The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the potential of precise shaping and adaptation to unique solutions, neodymium magnets can be produced in a broad palette of forms and dimensions, which expands the range of possible applications,
- Versatile presence in electronics industry – they serve a role in mass storage devices, electric motors, diagnostic systems, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in power. 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
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complicated shapes - preferred is a housing - magnet mounting.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a plate made of low-carbon steel, acting as a magnetic yoke
- whose thickness is min. 10 mm
- with a surface free of scratches
- with direct contact (without impurities)
- under axial force direction (90-degree angle)
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Air gap (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion 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 maximum value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Higher carbon content reduce magnetic permeability and holding force.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Pinching danger
Large magnets can crush fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Fire risk
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Phone sensors
GPS units and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Protective goggles
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Avoid contact if allergic
Some people have a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in a rash. We recommend wear protective gloves.
Permanent damage
Watch the temperature. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
No play value
These products are not suitable for play. Swallowing several magnets may result in them pinching intestinal walls, which poses a critical condition and requires urgent medical intervention.
Handling guide
Handle magnets consciously. Their powerful strength can shock even professionals. Be vigilant and do not underestimate their force.
Threat to electronics
Avoid bringing magnets near a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Medical implants
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
