Pros and cons of Nd2Fe14B magnets.
Benefits
- Their magnetic field is maintained, and after approximately ten years it decreases only by ~1% (according to research),
- They have excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
- Thanks to the shimmering finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an aesthetic appearance,
- Magnetic induction on the working layer of the magnet remains maximum,
- 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 forming and the capacity to adapt to unusual requirements,
- Versatile presence in advanced technology sectors – they find application in computer drives, drive modules, advanced medical instruments, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases 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 and 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 recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest a housing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small elements of these devices can complicate diagnosis medical after entering the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a surface perfectly flat
- with zero gap (without impurities)
- during pulling in a direction perpendicular to the plane
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Air gap (between the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate lowers the holding force.
H&S for magnets
Safe distance
Avoid bringing magnets near a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
Heat warning
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Powerful field
Use magnets with awareness. Their huge power can shock even professionals. Plan your moves and do not underestimate their force.
Medical interference
Patients with a ICD should maintain an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Allergic reactions
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands or select encased magnets.
Material brittleness
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them cracking into shards.
Finger safety
Pinching hazard: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Combustion hazard
Powder generated during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.
Compass and GPS
GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
No play value
Product intended for adults. Small elements pose a choking risk, causing severe trauma. Keep away from kids and pets.
