Strengths and weaknesses of rare earth magnets.
Benefits
- They have stable power, and over more than ten years their performance decreases symbolically – ~1% (in testing),
- They possess excellent resistance to magnetic field loss as a result of external fields,
- Thanks to the smooth finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an visually attractive appearance,
- Magnets have extremely high magnetic induction on the outer layer,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of accurate machining and optimizing to atypical requirements,
- Versatile presence in modern industrial fields – they are used in magnetic memories, electric drive systems, diagnostic systems, as well as other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 very resistant to heat
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these devices can complicate diagnosis medical after entering the body.
- Due to complex production process, their price is higher than average,
Pull force analysis
Highest magnetic holding force – what contributes to it?
- using a base made of mild steel, serving as a ideal flux conductor
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a plane free of scratches
- without the slightest air gap between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Steel thickness – too thin sheet does not close the flux, causing part of the power to be escaped into the air.
- Material type – ideal substrate is high-permeability steel. Cast iron may attract less.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
Safe handling of neodymium magnets
Protect data
Powerful magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Beware of splinters
Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.
Medical implants
Individuals with a pacemaker should maintain an large gap from magnets. The magnetism can disrupt the functioning of the implant.
Product not for children
NdFeB magnets are not intended for children. Accidental ingestion of multiple magnets may result in them attracting across intestines, which constitutes a direct threat to life and requires urgent medical intervention.
Permanent damage
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Warning for allergy sufferers
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If you have an allergy, avoid touching magnets with bare hands and opt for coated magnets.
Magnetic interference
A strong magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.
Do not underestimate power
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Do not drill into magnets
Combustion risk: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
Bodily injuries
Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
