Other offers
Pros and cons of neodymium magnets.
Strengths
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
- Magnets effectively resist against loss of magnetization caused by foreign field sources,
- Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an aesthetic appearance,
- Neodymium magnets create maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of individual shaping as well as modifying to complex applications,
- Significant place in advanced technology sectors – they are utilized in data components, motor assemblies, diagnostic systems, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in compact constructions
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures 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, when using outdoors
- Due to limitations in realizing threads and complex forms in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Additionally, small elements of these products are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- using a plate made of mild steel, acting as a circuit closing element
- with a cross-section no less than 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- under vertical force direction (90-degree angle)
- in neutral thermal conditions
Key elements affecting lifting force
- Air gap (between the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
- Surface finish – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
Bodily injuries
Large magnets can crush fingers in a fraction of a second. Do not put your hand between two strong magnets.
Protect data
Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Immense force
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Do not drill into magnets
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Magnetic interference
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your phone, device, and GPS.
Implant safety
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
This is not a toy
Always keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.
Magnet fragility
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets leads to them shattering into shards.
Metal Allergy
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop working with magnets and wear gloves.
Heat warning
Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and strength.
