Pros as well as cons of rare earth magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- They do not lose their magnetic properties even under close interference source,
- In other words, due to the shiny layer of gold, the element looks attractive,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the potential of free forming and customization to individualized solutions, magnetic components can be produced in a wide range of forms and dimensions, which makes them more universal,
- Huge importance in electronics industry – they are commonly used in HDD drives, motor assemblies, precision medical tools, as well as other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complicated forms in magnets, we propose using a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- using a plate made of mild steel, acting as a circuit closing element
- with a thickness of at least 10 mm
- characterized by smoothness
- under conditions of ideal adhesion (surface-to-surface)
- during detachment in a direction vertical to the plane
- at room temperature
Lifting capacity in real conditions – factors
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Safe handling of neodymium magnets
Fragile material
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them breaking into small pieces.
Swallowing risk
These products are not suitable for play. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires urgent medical intervention.
Magnetic interference
A strong magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent damaging the sensors.
Crushing force
Large magnets can break fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
Life threat
People with a heart stimulator must keep an absolute distance from magnets. The magnetism can stop the operation of the life-saving device.
Do not drill into magnets
Powder created during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Data carriers
Device Safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Conscious usage
Handle magnets consciously. Their powerful strength can shock even professionals. Plan your moves and respect their power.
Nickel coating and allergies
Studies show that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands or opt for encased magnets.
Permanent damage
Control the heat. Heating the magnet to high heat will ruin its magnetic structure and strength.
