Strengths as well as weaknesses of rare earth magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- A magnet with a smooth nickel surface is more attractive,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- In view of the ability of accurate shaping and adaptation to specialized solutions, NdFeB magnets can be created in a broad palette of geometric configurations, which expands the range of possible applications,
- Wide application in advanced technology sectors – they are utilized in hard drives, brushless drives, medical equipment, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose their force 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
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating threads in the magnet and complex shapes - recommended is casing - magnetic holder.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Highest magnetic holding force – what it depends on?
- using a base made of mild steel, functioning as a ideal flux conductor
- with a thickness minimum 10 mm
- with a plane free of scratches
- without the slightest insulating layer between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Determinants of practical lifting force of a magnet
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin plate causes magnetic saturation, causing part of the power to be lost to the other side.
- Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic permeability and lifting capacity.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Demagnetization risk
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Fragile material
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Health Danger
Warning for patients: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
Respect the power
Handle magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and respect their power.
Crushing force
Risk of injury: The pulling power is so great that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Keep away from computers
Avoid bringing magnets near a purse, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.
Machining danger
Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
This is not a toy
Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Store away from children and animals.
Keep away from electronics
An intense magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Maintain magnets close to a device to prevent damaging the sensors.
Nickel coating and allergies
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If you have an allergy, refrain from direct skin contact or choose coated magnets.
