Advantages as well as disadvantages of neodymium magnets.
Pros
- Their power is durable, and after approximately 10 years it drops only by ~1% (theoretically),
- They retain their magnetic properties even under external field action,
- A magnet with a shiny gold surface looks better,
- Magnets exhibit extremely high magnetic induction on the outer layer,
- 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...
- In view of the possibility of precise shaping and adaptation to unique requirements, NdFeB magnets 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 used in computer drives, brushless drives, medical equipment, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in miniature devices
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing threads and complex shapes in magnets, we recommend using cover - magnetic mount.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these products can be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a plate made of mild steel, serving as a ideal flux conductor
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- with zero gap (no impurities)
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Distance – existence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Sensitization to coating
Studies show that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact and select coated magnets.
Beware of splinters
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Do not overheat magnets
Avoid heat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Magnetic interference
A powerful magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a smartphone to avoid damaging the sensors.
Adults only
Only for adults. Small elements pose a choking risk, causing serious injuries. Store away from children and animals.
Machining danger
Powder produced during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Serious injuries
Protect your hands. Two large magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!
Electronic devices
Intense magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Powerful field
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Warning for heart patients
Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.
