Strengths as well as weaknesses of rare earth magnets.
Pros
- They have unchanged lifting capacity, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
- They maintain their magnetic properties even under strong external field,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of individual shaping as well as modifying to precise conditions,
- Wide application in future technologies – they are commonly used in HDD drives, motor assemblies, medical devices, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- 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, when using outdoors
- Limited possibility of producing threads in the magnet and complex shapes - recommended is cover - magnetic holder.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Holding force characteristics
Magnetic strength at its maximum – what it depends on?
- using a sheet made of high-permeability steel, serving as a ideal flux conductor
- with a thickness minimum 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- under vertical application of breakaway force (90-degree angle)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Distance – existence of foreign body (rust, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Fragile material
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
Flammability
Powder generated during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Demagnetization risk
Do not overheat. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Metal Allergy
Medical facts indicate that nickel (the usual finish) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands and select versions in plastic housing.
Immense force
Handle with care. Rare earth magnets act from a distance and connect with massive power, often faster than you can move away.
Keep away from children
Only for adults. Small elements pose a choking risk, causing severe trauma. Store away from children and animals.
Crushing risk
Large magnets can crush fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.
Impact on smartphones
Note: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
Cards and drives
Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.
Pacemakers
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
