Pros as well as cons of rare earth magnets.
Strengths
- Their magnetic field is maintained, and after around 10 years it drops only by ~1% (theoretically),
- Neodymium magnets are characterized by highly resistant to magnetic field loss caused by external magnetic fields,
- By applying a lustrous layer of silver, the element acquires an nice look,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the option of accurate forming and customization to specialized solutions, magnetic components can be created in a broad palette of geometric configurations, which amplifies use scope,
- Key role in advanced technology sectors – they are used in data components, brushless drives, precision medical tools, as well as other advanced devices.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- 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 improves its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in producing nuts and complex forms in magnets, we recommend using cover - magnetic mount.
- Health risk related to microscopic parts of magnets pose a threat, 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 devices can complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- whose thickness equals approx. 10 mm
- with a surface free of scratches
- with total lack of distance (no coatings)
- for force applied at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Key elements affecting lifting force
- Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Steel thickness – too thin sheet does not accept the full field, causing part of the power to be lost into the air.
- Steel grade – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Product not for children
Neodymium magnets are not toys. Eating multiple magnets may result in them connecting inside the digestive tract, which poses a critical condition and requires immediate surgery.
Implant safety
Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Bone fractures
Protect your hands. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
GPS Danger
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Cards and drives
Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Shattering risk
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Safe operation
Exercise caution. Rare earth magnets act from a distance and snap with huge force, often quicker than you can move away.
Combustion hazard
Powder produced during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, immediately stop working with magnets and use protective gear.
Permanent damage
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and pulling force.
