Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
- Neodymium magnets are highly resistant to demagnetization caused by external magnetic fields,
- By applying a smooth coating of gold, the element has an modern look,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of accurate modeling and adjusting to specific conditions,
- Wide application in electronics industry – they are commonly used in HDD drives, drive modules, precision medical tools, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited ability of producing nuts in the magnet and complex forms - recommended is casing - magnetic holder.
- Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical after entering the body.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- using a base made of high-permeability steel, serving as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- characterized by smoothness
- with zero gap (without paint)
- under vertical application of breakaway force (90-degree angle)
- at temperature room level
Lifting capacity in real conditions – factors
- Clearance – the presence of foreign body (paint, tape, air) acts as an insulator, which reduces capacity rapidly (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 maximum value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of NdFeB magnets
Crushing force
Big blocks can crush fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.
Risk of cracking
Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Operating temperature
Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Immense force
Exercise caution. Neodymium magnets act from a distance and snap with huge force, often quicker than you can react.
This is not a toy
Adult use only. Tiny parts pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.
Electronic hazard
Data protection: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Do not drill into magnets
Powder created during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
GPS Danger
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
Medical implants
Individuals with a heart stimulator should maintain an large gap from magnets. The magnetic field can stop the functioning of the implant.
Metal Allergy
Certain individuals have a contact allergy to Ni, which is the standard coating for neodymium magnets. Frequent touching might lead to an allergic reaction. We suggest use protective gloves.
