Strengths as well as weaknesses of rare earth magnets.
Advantages
- Their power is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- Magnets perfectly protect themselves against demagnetization caused by foreign field sources,
- A magnet with a metallic silver surface has better aesthetics,
- Neodymium magnets deliver maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- 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 versatility in shaping and the capacity to customize to specific needs,
- Universal use in high-tech industry – they are utilized in data components, electric drive systems, precision medical tools, also other advanced devices.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and 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 recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing threads and complex forms in magnets, we propose using casing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a block made of structural steel, effectively closing the magnetic field
- with a cross-section of at least 10 mm
- with a surface free of scratches
- without any clearance between the magnet and steel
- during detachment in a direction perpendicular to the plane
- in stable room temperature
Determinants of lifting force in real conditions
- Clearance – the presence of any layer (paint, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin plate does not accept the full field, causing part of the power to be escaped to the other side.
- Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Precautions when working with neodymium magnets
No play value
These products are not suitable for play. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates urgent medical intervention.
Keep away from electronics
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness happens, cease working with magnets and use protective gear.
Fragile material
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Electronic hazard
Do not bring magnets near a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Respect the power
Exercise caution. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can react.
Demagnetization risk
Do not overheat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Fire warning
Dust produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Bone fractures
Big blocks can break fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.
ICD Warning
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
