Advantages and disadvantages of neodymium magnets.
Pros
- They have unchanged lifting capacity, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
- They maintain their magnetic properties even under close interference source,
- Thanks to the shiny finish, the surface of nickel, gold, or silver-plated gives an professional appearance,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Due to the potential of precise molding and adaptation to unique requirements, neodymium magnets can be modeled in a wide range of geometric configurations, which expands the range of possible applications,
- Universal use in high-tech industry – they are utilized in computer drives, electric motors, medical equipment, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest cover - magnetic holder, due to difficulties in creating threads inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- with the use of a yoke made of special test steel, ensuring full magnetic saturation
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by lack of roughness
- without any clearance between the magnet and steel
- under axial force vector (90-degree angle)
- in temp. approx. 20°C
What influences lifting capacity in practice
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- 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 admixtures decrease magnetic properties and lifting capacity.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Machining danger
Dust created during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Pinching danger
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Thermal limits
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
Keep away from computers
Intense magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Keep away from electronics
Remember: neodymium magnets produce a field that interferes with precision electronics. Maintain a safe distance from your phone, tablet, and navigation systems.
Protective goggles
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them cracking into small pieces.
Nickel allergy
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.
Medical interference
Warning for patients: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Handling rules
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Product not for children
Strictly keep magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.
