Strengths as well as weaknesses of rare earth magnets.
Pros
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the reflective layer of silver, the element is aesthetically pleasing,
- They feature high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in constructing and the ability to adapt to complex applications,
- Fundamental importance in high-tech industry – they serve a role in data components, drive modules, diagnostic systems, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- using a base made of low-carbon steel, serving as a magnetic yoke
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a plane free of scratches
- without the slightest insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Clearance – the presence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was measured with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate lowers the holding force.
Warnings
Swallowing risk
These products are not toys. Accidental ingestion of several magnets can lead to them attracting across intestines, which poses a critical condition and necessitates immediate surgery.
Phone sensors
GPS units and smartphones are highly sensitive to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Implant safety
Individuals with a pacemaker have to maintain an absolute distance from magnets. The magnetic field can stop the operation of the implant.
Finger safety
Danger of trauma: The pulling power is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Skin irritation risks
A percentage of the population suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Prolonged contact might lead to a rash. We suggest use protective gloves.
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Electronic devices
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
Material brittleness
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Permanent damage
Avoid heat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Mechanical processing
Dust created during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
