Pros as well as cons of neodymium magnets.
Pros
- They retain full power for around ten years – the drop is just ~1% (in theory),
- Magnets perfectly protect themselves against demagnetization caused by external fields,
- In other words, due to the shiny surface of gold, the element becomes visually attractive,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which increases force concentration,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- In view of the option of free forming and customization to custom requirements, neodymium magnets can be modeled in a variety of forms and dimensions, which makes them more universal,
- Key role in high-tech industry – they are utilized in computer drives, electric drive systems, medical devices, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in miniature devices
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing nuts and complicated forms in magnets, we recommend using cover - magnetic mount.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- on a base made of mild steel, perfectly concentrating the magnetic field
- whose thickness is min. 10 mm
- with a plane free of scratches
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at room temperature
Lifting capacity in practice – influencing factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
- Surface condition – ground elements ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Dust explosion hazard
Dust produced during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Do not underestimate power
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Medical interference
Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Protect data
Powerful magnetic fields can destroy records on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.
GPS and phone interference
A strong magnetic field interferes with the functioning of compasses in phones and GPS navigation. Do not bring magnets near a device to prevent breaking the sensors.
This is not a toy
Neodymium magnets are not suitable for play. Eating a few magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and requires urgent medical intervention.
Pinching danger
Danger of trauma: The pulling power is so immense that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Do not overheat magnets
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Metal Allergy
It is widely known that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands and opt for encased magnets.
Shattering risk
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.
