Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- They have excellent resistance to magnetism drop due to external magnetic sources,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets possess huge magnetic induction on the outer side,
- 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...
- Possibility of accurate creating and adjusting to precise needs,
- Universal use in modern technologies – they serve a role in HDD drives, brushless drives, precision medical tools, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in small systems
Cons
- 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 demagnetize 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 very resistant to heat
- 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, when using outdoors
- We suggest a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section minimum 10 mm
- with a surface perfectly flat
- without any air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at room temperature
Practical lifting capacity: influencing factors
- Distance (between the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, rust or debris).
- Load vector – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Conscious usage
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Do not overheat magnets
Watch the temperature. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Life threat
For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.
GPS Danger
Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
Magnet fragility
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Adults only
Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Keep away from children and animals.
Combustion hazard
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Physical harm
Big blocks can smash fingers instantly. Never put your hand between two strong magnets.
Sensitization to coating
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease handling magnets and use protective gear.
Electronic hazard
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).
