Advantages as well as disadvantages of neodymium magnets.
Strengths
- They do not lose strength, even during around ten years – the drop in power is only ~1% (based on measurements),
- They are resistant to demagnetization induced by external magnetic fields,
- In other words, due to the smooth layer of silver, the element is aesthetically pleasing,
- Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Thanks to the possibility of flexible molding and adaptation to specialized projects, magnetic components can be manufactured in a variety of forms and dimensions, which amplifies use scope,
- Significant place in future technologies – they are utilized in HDD drives, electric drive systems, medical devices, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in producing nuts and complicated shapes in magnets, we recommend using casing - magnetic holder.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these devices can be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price exceeds standard values,
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- using a sheet made of mild steel, acting as a ideal flux conductor
- with a cross-section of at least 10 mm
- with a surface cleaned and smooth
- with direct contact (without paint)
- for force applied at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin sheet does not close the flux, causing part of the power to be escaped into the air.
- Steel grade – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface finish – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the load capacity.
Warnings
Precision electronics
A strong magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Keep magnets close to a device to prevent damaging the sensors.
Risk of cracking
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Bodily injuries
Risk of injury: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
Sensitization to coating
Some people experience a sensitization to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in a rash. We suggest use protective gloves.
Combustion hazard
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Product not for children
Adult use only. Tiny parts pose a choking risk, causing severe trauma. Store away from kids and pets.
Warning for heart patients
For implant holders: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or ask another person to handle the magnets.
Electronic devices
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Safe operation
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Heat sensitivity
Avoid heat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
