Pros as well as cons of neodymium magnets.
Benefits
- Their strength is maintained, and after around 10 years it decreases only by ~1% (theoretically),
- Magnets effectively defend themselves against demagnetization caused by ambient magnetic noise,
- By covering with a reflective coating of gold, the element presents an proper look,
- Magnets are distinguished by impressive magnetic induction on the active area,
- 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...
- Thanks to freedom in designing and the ability to adapt to unusual requirements,
- Wide application in innovative solutions – they are used in mass storage devices, electric motors, medical equipment, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in small systems
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated forms.
- 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. Additionally, tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- on a block made of mild steel, perfectly concentrating the magnetic field
- possessing a thickness of min. 10 mm to avoid saturation
- with a plane perfectly flat
- under conditions of no distance (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- at temperature room level
Practical aspects of lifting capacity – factors
- Clearance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be lost to the other side.
- Steel type – mild steel attracts best. Higher carbon content lower magnetic permeability and lifting capacity.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (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 shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
H&S for magnets
This is not a toy
Neodymium magnets are not suitable for play. Eating a few magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
Medical implants
For implant holders: Powerful magnets affect electronics. Maintain at least 30 cm distance or ask another person to handle the magnets.
Handling rules
Exercise caution. Rare earth magnets attract from a long distance and snap with massive power, often faster than you can move away.
Electronic hazard
Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop working with magnets and use protective gear.
Do not drill into magnets
Powder produced during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Bone fractures
Large magnets can break fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Beware of splinters
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Demagnetization risk
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Magnetic interference
A powerful magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to prevent breaking the sensors.
