Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- Magnets perfectly defend themselves against demagnetization caused by foreign field sources,
- By covering with a reflective layer of nickel, the element gains an nice look,
- Magnets have excellent magnetic induction on the surface,
- 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...
- Thanks to modularity in constructing and the capacity to modify to complex applications,
- Significant place in innovative solutions – they find application in hard drives, brushless drives, diagnostic systems, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves 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 power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complex forms in magnets, we propose using casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Highest magnetic holding force – what affects it?
- using a base made of high-permeability steel, serving as a circuit closing element
- whose thickness equals approx. 10 mm
- with a surface cleaned and smooth
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
What influences lifting capacity in practice
- Distance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel type – mild steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Safe operation
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
ICD Warning
For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Do not give to children
Adult use only. Tiny parts can be swallowed, causing intestinal necrosis. Store away from children and animals.
Operating temperature
Watch the temperature. Heating the magnet to high heat will destroy its properties and pulling force.
Crushing risk
Big blocks can break fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.
Data carriers
Data protection: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Warning for allergy sufferers
Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact and choose encased magnets.
Magnetic interference
Note: neodymium magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, device, and GPS.
Fire risk
Powder produced during cutting of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Fragile material
Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
