Pros as well as cons of neodymium magnets.
Pros
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- They possess excellent resistance to magnetism drop when exposed to external fields,
- Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an professional appearance,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the ability of precise molding and customization to custom needs, NdFeB magnets can be created in a broad palette of geometric configurations, which increases their versatility,
- Universal use in innovative solutions – they find application in hard drives, electric drive systems, advanced medical instruments, also multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- 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?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- with a cross-section of at least 10 mm
- with an polished contact surface
- under conditions of ideal adhesion (metal-to-metal)
- under axial force vector (90-degree angle)
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Distance – the presence of any layer (rust, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember 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.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – mild steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Base smoothness – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Power loss in heat
Keep cool. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Protect data
Device Safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).
Adults only
NdFeB magnets are not intended for children. Swallowing a few magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates urgent medical intervention.
Allergic reactions
A percentage of the population have a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Prolonged contact might lead to an allergic reaction. We recommend wear safety gloves.
Physical harm
Danger of trauma: The pulling power is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Fragile material
Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Machining danger
Powder created during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Warning for heart patients
Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Handling guide
Use magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their force.
GPS Danger
Note: neodymium magnets produce a field that confuses precision electronics. Keep a separation from your mobile, tablet, and navigation systems.
