Advantages and disadvantages of neodymium magnets.
Pros
- Their power is durable, and after approximately 10 years it drops only by ~1% (according to research),
- They feature excellent resistance to magnetic field loss as a result of opposing magnetic fields,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
- Thanks to freedom in constructing and the capacity to modify to unusual requirements,
- Huge importance in future technologies – they serve a role in mass storage devices, electromotive mechanisms, medical devices, also multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- At very strong impacts they can crack, 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 decrease their force 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited ability of making threads in the magnet and complicated shapes - preferred is a housing - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Additionally, small elements of these products can complicate diagnosis medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- possessing a massiveness of at least 10 mm to avoid saturation
- with an ideally smooth touching surface
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Practical aspects of lifting capacity – factors
- Gap (between the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick steel does not close the flux, causing part of the flux to be lost to the other side.
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.
Warnings
Bodily injuries
Risk of injury: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Fire risk
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Maximum temperature
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Keep away from electronics
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Allergic reactions
Some people have a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to dermatitis. We suggest wear safety gloves.
This is not a toy
These products are not intended for children. Swallowing a few magnets can lead to them attracting across intestines, which poses a critical condition and requires urgent medical intervention.
Beware of splinters
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.
Warning for heart patients
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Electronic hazard
Device Safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
Immense force
Handle magnets with awareness. Their huge power can surprise even experienced users. Plan your moves and respect their force.
