Pros and cons of neodymium magnets.
Advantages
- They do not lose power, even during nearly 10 years – the reduction in lifting capacity is only ~1% (according to tests),
- They do not lose their magnetic properties even under close interference source,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Considering the possibility of free molding and adaptation to custom solutions, neodymium magnets can be modeled in a wide range of geometric configurations, which expands the range of possible applications,
- Key role in high-tech industry – they are commonly used in HDD drives, motor assemblies, advanced medical instruments, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in miniature devices
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest 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 immune to moisture, in case of application outdoors
- Limited possibility of producing nuts in the magnet and complicated shapes - preferred is casing - magnet mounting.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products can complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Highest magnetic holding force – what contributes to it?
- using a base made of low-carbon steel, functioning as a magnetic yoke
- whose transverse dimension is min. 10 mm
- with an ground touching surface
- with zero gap (no paint)
- under axial force vector (90-degree angle)
- at temperature room level
Determinants of lifting force in real conditions
- Distance – existence of foreign body (paint, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be escaped to the other side.
- Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the load capacity.
Safe handling of neodymium magnets
Heat warning
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Allergic reactions
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, immediately stop handling magnets and use protective gear.
Protective goggles
Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Magnetic interference
A strong magnetic field disrupts the operation of compasses in phones and GPS navigation. Maintain magnets close to a smartphone to prevent breaking the sensors.
Health Danger
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Handling rules
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Magnetic media
Data protection: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Physical harm
Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Mechanical processing
Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Adults only
NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
