Pros and cons of neodymium magnets.
Pros
- They have unchanged lifting capacity, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
- They possess excellent resistance to weakening of magnetic properties due to external magnetic sources,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the surface of the magnet remains exceptional,
- 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...
- Considering the ability of accurate molding and adaptation to unique solutions, NdFeB magnets can be created in a variety of forms and dimensions, which amplifies use scope,
- Versatile presence in future technologies – they are utilized in mass storage devices, electromotive mechanisms, medical equipment, also technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their power 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
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making threads in the magnet and complicated forms - preferred is casing - magnet mounting.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a plate made of high-permeability steel, serving as a ideal flux conductor
- with a cross-section of at least 10 mm
- characterized by smoothness
- with zero gap (without paint)
- during pulling in a direction vertical to the plane
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Air gap (between the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material composition – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface structure – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet and the plate decreases the holding force.
Warnings
Pacemakers
For implant holders: Powerful magnets affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Protect data
Powerful magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Handling guide
Handle magnets with awareness. Their huge power can shock even professionals. Plan your moves and respect their power.
Risk of cracking
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Threat to navigation
Note: rare earth magnets generate a field that disrupts precision electronics. Maintain a separation from your phone, device, and GPS.
Machining danger
Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Keep away from children
These products are not toys. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.
Allergic reactions
A percentage of the population suffer from a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Extended handling may cause skin redness. We recommend use protective gloves.
Bone fractures
Mind your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Thermal limits
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
