Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- Their strength is durable, and after approximately ten years it decreases only by ~1% (according to research),
- They do not lose their magnetic properties even under external field action,
- Thanks to the shimmering finish, the plating of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Considering the possibility of free shaping and adaptation to unique solutions, magnetic components can be manufactured in a broad palette of forms and dimensions, which amplifies use scope,
- Huge importance in high-tech industry – they serve a role in mass storage devices, electric drive systems, medical devices, also complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. 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 force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and 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
- Limited possibility of creating nuts in the magnet and complicated forms - recommended is casing - magnet mounting.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these devices can disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension equals approx. 10 mm
- characterized by smoothness
- without any insulating layer between the magnet and steel
- under vertical force vector (90-degree angle)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Gap (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Alloy steels decrease magnetic properties and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.
Warnings
Warning for heart patients
Warning for patients: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.
Beware of splinters
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them cracking into shards.
Pinching danger
Large magnets can crush fingers instantly. Do not put your hand betwixt two strong magnets.
Data carriers
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.
Do not overheat magnets
Avoid heat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Do not drill into magnets
Machining of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Phone sensors
Remember: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, device, and GPS.
Avoid contact if allergic
A percentage of the population suffer from a sensitization to Ni, which is the typical protective layer for neodymium magnets. Extended handling may cause dermatitis. We strongly advise use safety gloves.
Powerful field
Be careful. Rare earth magnets attract from a long distance and connect with huge force, often faster than you can react.
Keep away from children
Only for adults. Small elements pose a choking risk, leading to intestinal necrosis. Keep away from children and animals.
