Strengths and weaknesses of neodymium magnets.
Benefits
- They retain magnetic properties for around 10 years – the loss is just ~1% (according to analyses),
- Magnets very well defend themselves against demagnetization caused by foreign field sources,
- In other words, due to the smooth surface of gold, the element gains visual value,
- Magnetic induction on the working part of the magnet turns out to be very high,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- In view of the possibility of precise forming and customization to individualized needs, NdFeB magnets can be produced in a broad palette of shapes and sizes, which expands the range of possible applications,
- Universal use in high-tech industry – they are utilized in data components, electromotive mechanisms, advanced medical instruments, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in miniature devices
Weaknesses
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited possibility of creating nuts in the magnet and complex forms - recommended is cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- with the application of a sheet made of special test steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- with an ideally smooth touching surface
- with zero gap (no coatings)
- under vertical application of breakaway force (90-degree angle)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Temperature – heating the magnet 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, in contrast under shearing force the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Magnetic media
Do not bring magnets near a wallet, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Phone sensors
Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
Crushing force
Danger of trauma: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Heat sensitivity
Standard neodymium magnets (grade N) lose power when the temperature exceeds 80°C. Damage is permanent.
Life threat
People with a ICD have to maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the life-saving device.
Nickel allergy
Studies show that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands or opt for versions in plastic housing.
Fragile material
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Swallowing risk
These products are not toys. Eating several magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.
Combustion hazard
Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Do not underestimate power
Be careful. Neodymium magnets act from a distance and snap with huge force, often faster than you can move away.
