Strengths and weaknesses of rare earth magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Neodymium magnets are distinguished by exceptionally resistant to demagnetization caused by external interference,
- Thanks to the reflective finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
- Neodymium magnets create maximum magnetic induction on a small surface, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of detailed forming and modifying to atypical requirements,
- Significant place in advanced technology sectors – they serve a role in computer drives, electric motors, precision medical tools, and complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complicated shapes in magnets, we recommend using cover - magnetic holder.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Furthermore, small components of these devices are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an ideally smooth contact surface
- without any clearance between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin plate does not close the flux, causing part of the flux to be escaped to the other side.
- Material type – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Warnings
Shattering risk
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets leads to them breaking into small pieces.
Implant safety
Warning for patients: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Do not drill into magnets
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Nickel allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop working with magnets and wear gloves.
Choking Hazard
Neodymium magnets are not suitable for play. Swallowing multiple magnets can lead to them attracting across intestines, which constitutes a severe health hazard and necessitates immediate surgery.
Heat sensitivity
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Physical harm
Danger of trauma: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
Keep away from computers
Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Caution required
Use magnets with awareness. Their huge power can surprise even experienced users. Stay alert and do not underestimate their power.
Magnetic interference
Note: neodymium magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your mobile, device, and navigation systems.
