Advantages as well as disadvantages of neodymium magnets.
Benefits
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Magnets very well defend themselves against demagnetization caused by external fields,
- In other words, due to the reflective surface of nickel, the element gains a professional look,
- They feature high magnetic induction at the operating surface, which increases their power,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of individual machining and adapting to individual applications,
- Wide application in electronics industry – they are used in hard drives, drive modules, advanced medical instruments, also other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing nuts and complex forms in magnets, we propose using a housing - magnetic holder.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small elements of these products are able to be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- with a thickness of at least 10 mm
- with an ideally smooth contact surface
- with zero gap (no coatings)
- under perpendicular application of breakaway force (90-degree angle)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal conditions – neodymium magnets 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 testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Caution required
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.
Material brittleness
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Allergy Warning
Certain individuals have a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Prolonged contact might lead to dermatitis. It is best to use safety gloves.
Bodily injuries
Large magnets can break fingers instantly. Never place your hand between two attracting surfaces.
Dust explosion hazard
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
GPS and phone interference
A strong magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Maintain magnets near a smartphone to avoid breaking the sensors.
Warning for heart patients
People with a pacemaker should maintain an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Keep away from computers
Device Safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, medical aids, mechanical watches).
Demagnetization risk
Monitor thermal conditions. Exposing the magnet to high heat will ruin its properties and pulling force.
Keep away from children
Adult use only. Small elements pose a choking risk, leading to serious injuries. Store away from children and animals.
