Strengths as well as weaknesses of rare earth magnets.
Advantages
- They do not lose strength, even during nearly ten years – the decrease in lifting capacity is only ~1% (theoretically),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a shiny silver surface has better aesthetics,
- Magnets have extremely high magnetic induction on the outer layer,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of custom modeling and adapting to complex needs,
- Fundamental importance in modern technologies – they are utilized in computer drives, brushless drives, medical equipment, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- with a plane free of scratches
- without any air gap between the magnet and steel
- under axial force vector (90-degree angle)
- in stable room temperature
Key elements affecting lifting force
- Space between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin plate does not accept the full field, causing part of the power to be escaped into the air.
- Plate material – low-carbon steel attracts best. Higher carbon content lower magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.
Warnings
Do not drill into magnets
Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Choking Hazard
Neodymium magnets are not toys. Swallowing multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires immediate surgery.
Skin irritation risks
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, cease working with magnets and use protective gear.
Beware of splinters
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them shattering into shards.
Handling rules
Exercise caution. Neodymium magnets act from a distance and connect with massive power, often quicker than you can react.
Protect data
Device Safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Threat to navigation
Navigation devices and smartphones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Danger to pacemakers
For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Thermal limits
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and pulling force.
Finger safety
Large magnets can break fingers instantly. Do not place your hand betwixt two attracting surfaces.
