Pros and cons of Nd2Fe14B magnets.
Benefits
- Their power is durable, and after around 10 years it drops only by ~1% (theoretically),
- They do not lose their magnetic properties even under strong external field,
- A magnet with a metallic gold surface has an effective appearance,
- Magnets possess very high magnetic induction on the active area,
- 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...
- Due to the ability of flexible shaping and adaptation to custom solutions, neodymium magnets can be produced in a variety of geometric configurations, which expands the range of possible applications,
- Fundamental importance in innovative solutions – they are commonly used in computer drives, electromotive mechanisms, advanced medical instruments, as well as modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their strength 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 - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complex shapes in magnets, we propose using casing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- with a cross-section minimum 10 mm
- with an ideally smooth contact surface
- with zero gap (no impurities)
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
What influences lifting capacity in practice
- Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate decreases the holding force.
Warnings
Dust explosion hazard
Powder produced during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Safe operation
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Pinching danger
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
No play value
Neodymium magnets are not toys. Swallowing several magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires immediate surgery.
Maximum temperature
Control the heat. Heating the magnet to high heat will ruin its properties and pulling force.
Magnetic interference
GPS units and mobile phones are extremely sensitive to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Material brittleness
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Sensitization to coating
Medical facts indicate that nickel (the usual finish) is a strong allergen. If you have an allergy, refrain from direct skin contact and choose coated magnets.
Safe distance
Equipment safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Implant safety
People with a ICD should keep an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.
