Pros as well as cons of rare earth magnets.
Pros
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (according to theory),
- Magnets perfectly resist against loss of magnetization caused by ambient magnetic noise,
- A magnet with a shiny gold surface has better aesthetics,
- Neodymium magnets generate maximum magnetic induction on a small area, which increases force concentration,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in shaping and the capacity to modify to specific needs,
- Universal use in electronics industry – they serve a role in data components, electric drive systems, diagnostic systems, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in miniature devices
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex shapes.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these devices can complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- using a plate made of mild steel, serving as a magnetic yoke
- possessing a massiveness of min. 10 mm to avoid saturation
- with a surface cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction perpendicular to the mounting surface
- at standard ambient temperature
Determinants of lifting force in real conditions
- Clearance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Plate thickness – too thin sheet does not close the flux, causing part of the power to be wasted into the air.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Danger to pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Choking Hazard
These products are not intended for children. Eating multiple magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.
Protective goggles
Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Allergic reactions
A percentage of the population experience a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Prolonged contact can result in a rash. We strongly advise wear protective gloves.
Hand protection
Big blocks can smash fingers instantly. Never place your hand betwixt two attracting surfaces.
Power loss in heat
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Electronic devices
Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Do not drill into magnets
Fire warning: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
Magnetic interference
Note: neodymium magnets produce a field that confuses sensitive sensors. Keep a separation from your mobile, device, and navigation systems.
Do not underestimate power
Be careful. Neodymium magnets act from a distance and snap with massive power, often faster than you can move away.
