Strengths and weaknesses of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- They are resistant to demagnetization induced by external field influence,
- By applying a smooth coating of nickel, the element has an aesthetic look,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- 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...
- Possibility of custom modeling and modifying to defined requirements,
- Significant place in advanced technology sectors – they are utilized in hard drives, motor assemblies, advanced medical instruments, and modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Weaknesses
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating threads in the magnet and complex shapes - recommended is casing - magnetic holder.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a plate made of high-permeability steel, acting as a magnetic yoke
- with a thickness of at least 10 mm
- characterized by even structure
- under conditions of gap-free contact (surface-to-surface)
- under axial application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Air gap (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be lost to the other side.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface finish – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
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 fivefold. In addition, even a slight gap between the magnet and the plate decreases the holding force.
Safe handling of NdFeB magnets
Heat sensitivity
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
GPS Danger
Navigation devices and smartphones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Keep away from children
These products are not intended for children. Swallowing multiple magnets may result in them pinching intestinal walls, which poses a direct threat to life and necessitates urgent medical intervention.
Protect data
Data protection: Strong magnets can damage data carriers and sensitive devices (heart implants, medical aids, mechanical watches).
Allergy Warning
Certain individuals suffer from a sensitization to Ni, which is the typical protective layer for neodymium magnets. Frequent touching might lead to dermatitis. We recommend wear safety gloves.
Dust explosion hazard
Machining of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Material brittleness
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Implant safety
Patients with a ICD have to maintain an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
Crushing risk
Pinching hazard: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Safe operation
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
