Strengths as well as weaknesses of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
- They show high resistance to demagnetization induced by external disturbances,
- By using a shiny layer of gold, the element presents an aesthetic look,
- Magnetic induction on the surface of the magnet remains maximum,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of individual creating as well as optimizing to defined applications,
- Versatile presence in advanced technology sectors – they are utilized in computer drives, drive modules, medical equipment, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- using a sheet made of high-permeability steel, functioning as a circuit closing element
- with a cross-section no less than 10 mm
- with a surface perfectly flat
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at temperature room level
Determinants of lifting force in real conditions
- Distance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may attract less.
- Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Allergic reactions
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.
Finger safety
Large magnets can crush fingers instantly. Under no circumstances place your hand between two attracting surfaces.
Danger to pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Do not underestimate power
Exercise caution. Neodymium magnets attract from a long distance and snap with huge force, often faster than you can react.
Combustion hazard
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Compass and GPS
A strong magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Keep magnets close to a device to prevent breaking the sensors.
Keep away from children
Only for adults. Small elements can be swallowed, leading to serious injuries. Store out of reach of children and animals.
Material brittleness
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Electronic hazard
Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Power loss in heat
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
