Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- Their strength is maintained, and after around 10 years it drops only by ~1% (according to research),
- They have excellent resistance to magnetism drop as a result of external magnetic sources,
- By covering with a decorative coating of gold, the element has an modern look,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of detailed machining as well as adjusting to precise needs,
- Significant place in high-tech industry – they are utilized in computer drives, motor assemblies, precision medical tools, and complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited ability of creating threads in the magnet and complicated forms - preferred is cover - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these magnets can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a block made of mild steel, effectively closing the magnetic field
- whose thickness equals approx. 10 mm
- characterized by even structure
- without the slightest air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal weaken the grip.
- Thermal factor – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Magnetic media
Device Safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
Choking Hazard
Strictly keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are tragic.
Metal Allergy
It is widely known that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, prevent direct skin contact or select encased magnets.
Shattering risk
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets leads to them cracking into shards.
Hand protection
Large magnets can crush fingers instantly. Under no circumstances place your hand between two strong magnets.
Safe operation
Be careful. Neodymium magnets attract from a distance and snap with massive power, often faster than you can move away.
Health Danger
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
Demagnetization risk
Control the heat. Exposing the magnet to high heat will destroy its properties and pulling force.
Keep away from electronics
A powerful magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Maintain magnets near a device to prevent damaging the sensors.
Do not drill into magnets
Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
