Pros and cons of rare earth magnets.
Benefits
- Their strength remains stable, and after around ten years it drops only by ~1% (theoretically),
- They maintain their magnetic properties even under close interference source,
- Thanks to the shiny finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an elegant appearance,
- Magnets are distinguished by extremely high magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of exact creating and adjusting to atypical applications,
- Key role in high-tech industry – they find application in HDD drives, brushless drives, precision medical tools, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited ability of creating threads in the magnet and complex shapes - recommended is cover - mounting mechanism.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these devices are able to complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- using a plate made of mild steel, functioning as a ideal flux conductor
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- without any air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin steel does not close the flux, causing part of the flux to be escaped to the other side.
- Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
Impact on smartphones
An intense magnetic field interferes with the functioning of compasses in phones and GPS navigation. Keep magnets close to a device to prevent breaking the sensors.
Danger to the youngest
Always store magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.
Implant safety
For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Threat to electronics
Equipment safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
Dust explosion hazard
Dust generated during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Skin irritation risks
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation appears, immediately stop working with magnets and use protective gear.
Handling guide
Exercise caution. Neodymium magnets act from a distance and connect with huge force, often quicker than you can move away.
Power loss in heat
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Crushing force
Big blocks can crush fingers instantly. Under no circumstances put your hand between two attracting surfaces.
Material brittleness
Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.
