Pros as well as cons of neodymium magnets.
Pros
- They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- They have excellent resistance to magnetic field loss when exposed to external magnetic sources,
- A magnet with a metallic silver surface has better aesthetics,
- Magnetic induction on the top side of the magnet turns out to be very high,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of detailed creating and modifying to atypical requirements,
- Wide application in future technologies – they find application in hard drives, motor assemblies, medical equipment, and multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in force. 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- using a plate made of low-carbon steel, functioning as a circuit closing element
- whose transverse dimension is min. 10 mm
- with a plane free of scratches
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin steel causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Plate material – mild steel gives the best results. Higher carbon content lower magnetic permeability and holding force.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate reduces the lifting capacity.
Electronic hazard
Data protection: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).
Immense force
Handle magnets with awareness. Their huge power can shock even professionals. Stay alert and do not underestimate their force.
Material brittleness
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Mechanical processing
Dust created during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Do not overheat magnets
Do not overheat. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Phone sensors
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Crushing force
Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Product not for children
These products are not suitable for play. Swallowing a few magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
Nickel coating and allergies
It is widely known that nickel (the usual finish) is a common allergen. If you have an allergy, refrain from direct skin contact and opt for coated magnets.
Health Danger
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
