Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even during approximately ten years – the decrease in strength is only ~1% (theoretically),
- They show high resistance to demagnetization induced by external disturbances,
- By covering with a decorative layer of silver, the element has an aesthetic look,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of exact creating and optimizing to concrete conditions,
- Wide application in electronics industry – they are used in data components, electric motors, advanced medical instruments, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making threads in the magnet and complex forms - recommended is casing - magnetic holder.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these magnets are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- with an ideally smooth contact surface
- with direct contact (without impurities)
- under perpendicular force direction (90-degree angle)
- at temperature room level
Determinants of practical lifting force of a magnet
- Clearance – the presence of foreign body (paint, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Cast iron may attract less.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate reduces the load capacity.
H&S for magnets
Physical harm
Large magnets can crush fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Protective goggles
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
GPS and phone interference
Remember: neodymium magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and GPS.
Immense force
Handle with care. Neodymium magnets attract from a long distance and snap with huge force, often faster than you can move away.
Thermal limits
Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Electronic hazard
Device Safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Dust is flammable
Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
ICD Warning
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Swallowing risk
NdFeB magnets are not toys. Eating multiple magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.
Nickel coating and allergies
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease working with magnets and wear gloves.
