Pros as well as cons of rare earth magnets.
Pros
- They do not lose magnetism, even during approximately ten years – the reduction in power is only ~1% (based on measurements),
- They possess excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- In other words, due to the metallic layer of nickel, the element looks attractive,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of precise forming as well as adjusting to atypical requirements,
- Versatile presence in advanced technology sectors – they serve a role in hard drives, brushless drives, precision medical tools, as well as multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their 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 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 advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using cover - magnetic mount.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Maximum lifting force for a neodymium magnet – what affects it?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a thickness minimum 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- under vertical force vector (90-degree angle)
- at conditions approx. 20°C
What influences lifting capacity in practice
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel attracts identically. High carbon content worsen the attraction effect.
- Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Heat sensitivity
Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Magnetic interference
GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Keep away from computers
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Choking Hazard
NdFeB magnets are not suitable for play. Eating multiple magnets can lead to them attracting across intestines, which poses a direct threat to life and requires urgent medical intervention.
Bone fractures
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!
Powerful field
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Nickel allergy
Studies show that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from touching magnets with bare hands or choose versions in plastic housing.
Risk of cracking
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Mechanical processing
Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Pacemakers
Warning for patients: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
