Strengths as well as weaknesses of rare earth magnets.
Pros
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- Neodymium magnets remain exceptionally resistant to magnetic field loss caused by external magnetic fields,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Possibility of precise shaping as well as modifying to specific requirements,
- Key role in high-tech industry – they are utilized in data components, electric drive systems, precision medical tools, and modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- 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.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating threads and complex forms in magnets, we propose using casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- with a thickness minimum 10 mm
- with a plane cleaned and smooth
- with total lack of distance (no coatings)
- under axial force vector (90-degree angle)
- at standard ambient temperature
Magnet lifting force in use – key factors
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Metal type – not every steel attracts identically. Alloy additives worsen the attraction effect.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Precision electronics
GPS units and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Nickel allergy
Medical facts indicate that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, refrain from touching magnets with bare hands and select coated magnets.
Safe distance
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Heat sensitivity
Watch the temperature. Exposing the magnet to high heat will ruin its properties and pulling force.
Danger to pacemakers
Patients with a heart stimulator must maintain an absolute distance from magnets. The magnetism can interfere with the operation of the implant.
Do not drill into magnets
Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Choking Hazard
These products are not toys. Accidental ingestion of multiple magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires immediate surgery.
Do not underestimate power
Use magnets consciously. Their powerful strength can shock even experienced users. Be vigilant and respect their force.
Protective goggles
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.
Finger safety
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
