Pros and cons of neodymium magnets.
Advantages
- They retain full power for around ten years – the loss is just ~1% (based on simulations),
- Magnets perfectly resist against loss of magnetization caused by foreign field sources,
- A magnet with a shiny nickel surface has an effective appearance,
- Magnetic induction on the top side of the magnet turns out to be maximum,
- 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...
- In view of the possibility of accurate forming and adaptation to individualized requirements, neodymium magnets can be manufactured in a wide range of forms and dimensions, which makes them more universal,
- Huge importance in future technologies – they are commonly used in data components, drive modules, diagnostic systems, and technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing threads in the magnet and complex shapes - preferred is casing - magnet mounting.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets can be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a thickness no less than 10 mm
- with an ideally smooth contact surface
- with direct contact (without coatings)
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, rust or dirt).
- Load vector – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Chemical composition of the base – mild steel attracts best. Alloy admixtures lower magnetic properties and lifting capacity.
- Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Warnings
Risk of cracking
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Do not overheat magnets
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Avoid contact if allergic
A percentage of the population experience a contact allergy to nickel, which is the common plating for NdFeB magnets. Frequent touching may cause a rash. It is best to use protective gloves.
Fire warning
Dust created during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Protect data
Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Warning for heart patients
People with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can stop the operation of the implant.
Powerful field
Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their force.
GPS and phone interference
An intense magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Keep magnets close to a device to avoid damaging the sensors.
Product not for children
Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.
Pinching danger
Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!
