Pros and cons of neodymium magnets.
Advantages
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- Neodymium magnets are characterized by remarkably resistant to loss of magnetic properties caused by external interference,
- In other words, due to the reflective surface of silver, the element gains visual value,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
- Thanks to the possibility of accurate forming and adaptation to individualized solutions, magnetic components can be created in a broad palette of forms and dimensions, which increases their versatility,
- Key role in modern industrial fields – they serve a role in hard drives, electric motors, precision medical tools, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in small systems
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating threads in the magnet and complicated shapes - recommended is cover - mounting mechanism.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these products can complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a base made of mild steel, optimally conducting the magnetic flux
- whose thickness is min. 10 mm
- characterized by smoothness
- with zero gap (without paint)
- under vertical force direction (90-degree angle)
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Distance (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the holding force.
Safety rules for work with neodymium magnets
Flammability
Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Do not underestimate power
Use magnets with awareness. Their immense force can shock even experienced users. Stay alert and respect their power.
Medical implants
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Operating temperature
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
GPS and phone interference
Remember: rare earth magnets generate a field that interferes with precision electronics. Keep a separation from your mobile, tablet, and GPS.
Swallowing risk
Product intended for adults. Small elements can be swallowed, causing intestinal necrosis. Store away from children and animals.
Serious injuries
Pinching hazard: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Magnet fragility
Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Electronic hazard
Equipment safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
Nickel allergy
A percentage of the population have a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Prolonged contact can result in dermatitis. It is best to wear protective gloves.
