Strengths and weaknesses of rare earth magnets.
Benefits
- Their magnetic field is maintained, and after approximately 10 years it decreases only by ~1% (according to research),
- They feature excellent resistance to magnetic field loss when exposed to external magnetic sources,
- In other words, due to the smooth surface of silver, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to modularity in forming and the ability to modify to client solutions,
- Versatile presence in future technologies – they are used in HDD drives, electric drive systems, precision medical tools, and industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- We suggest casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these devices can complicate diagnosis 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 increases costs of application in large quantities
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with an polished touching surface
- with total lack of distance (without paint)
- under vertical force vector (90-degree angle)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.
Precautions when working with neodymium magnets
Pinching danger
Big blocks can smash fingers instantly. Never place your hand between two attracting surfaces.
Do not give to children
Product intended for adults. Tiny parts can be swallowed, leading to severe trauma. Keep out of reach of kids and pets.
Health Danger
Patients with a ICD should maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Maximum temperature
Do not overheat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Nickel coating and allergies
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, refrain from touching magnets with bare hands and choose encased magnets.
Protective goggles
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Do not drill into magnets
Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Handling guide
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Safe distance
Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.
Threat to navigation
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.
