Strengths as well as weaknesses of neodymium magnets.
Benefits
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- They feature excellent resistance to magnetic field loss as a result of external fields,
- A magnet with a smooth gold surface is more attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to modularity in forming and the ability to modify to unusual requirements,
- Huge importance in advanced technology sectors – they serve a role in HDD drives, electromotive mechanisms, medical devices, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating threads in the magnet and complex shapes - preferred is a housing - magnet mounting.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these magnets are able to complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a cross-section of at least 10 mm
- with an ground touching surface
- without the slightest clearance between the magnet and steel
- under vertical force direction (90-degree angle)
- at standard ambient temperature
Key elements affecting lifting force
- Gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be lost to the other side.
- Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
- Surface finish – full contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal environment – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Operating temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Mechanical processing
Powder created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Danger to the youngest
Adult use only. Small elements pose a choking risk, leading to serious injuries. Store out of reach of kids and pets.
Health Danger
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
GPS Danger
A strong magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.
Magnetic media
Equipment safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Sensitization to coating
Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop handling magnets and wear gloves.
Hand protection
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!
Protective goggles
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Handling rules
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
