Pros as well as cons of rare earth magnets.
Benefits
- Their power remains stable, and after approximately ten years it drops only by ~1% (according to research),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by magnetic disturbances,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing 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...
- Considering the potential of accurate molding and adaptation to individualized projects, magnetic components can be manufactured in a wide range of forms and dimensions, which expands the range of possible applications,
- Versatile presence in innovative solutions – they are commonly used in data components, electric drive systems, advanced medical instruments, also multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex shapes in magnets, we propose using a housing - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- using a base made of mild steel, functioning as a circuit closing element
- with a thickness no less than 10 mm
- with a plane cleaned and smooth
- with zero gap (no coatings)
- for force acting at a right angle (pull-off, not shear)
- at temperature room level
What influences lifting capacity in practice
- Clearance – the presence of foreign body (paint, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Plate material – mild steel gives the best results. Alloy admixtures decrease magnetic permeability and holding force.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Data carriers
Very strong magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Heat warning
Watch the temperature. Exposing the magnet to high heat will destroy its properties and strength.
Material brittleness
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Handling guide
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Bodily injuries
Large magnets can crush fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.
Nickel coating and allergies
Certain individuals have a sensitization to nickel, which is the common plating for neodymium magnets. Prolonged contact may cause skin redness. We recommend wear protective gloves.
Do not give to children
NdFeB magnets are not toys. Eating multiple magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and requires immediate surgery.
Do not drill into magnets
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Medical interference
Patients with a ICD must maintain an absolute distance from magnets. The magnetism can stop the functioning of the implant.
Magnetic interference
Note: neodymium magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, device, and GPS.
