Pros and cons of neodymium magnets.
Benefits
- They do not lose magnetism, even during nearly 10 years – the reduction in power is only ~1% (based on measurements),
- Neodymium magnets are characterized by extremely resistant to loss of magnetic properties caused by external field sources,
- Thanks to the shiny finish, the surface of nickel, gold-plated, or silver gives an clean appearance,
- Magnetic induction on the working layer of the magnet turns out to be impressive,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the option of accurate forming and adaptation to custom needs, neodymium magnets can be manufactured in a broad palette of geometric configurations, which makes them more universal,
- Versatile presence in modern industrial fields – they serve a role in HDD drives, motor assemblies, precision medical tools, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in compact constructions
Cons
- At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited possibility of making nuts in the magnet and complicated shapes - preferred is a housing - magnet mounting.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic flux
- with a thickness of at least 10 mm
- with a surface free of scratches
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Chemical composition of the base – mild steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Fragile material
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them breaking into small pieces.
ICD Warning
Individuals with a heart stimulator have to keep an safe separation from magnets. The magnetism can stop the functioning of the life-saving device.
Serious injuries
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Swallowing risk
NdFeB magnets are not intended for children. Swallowing a few magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.
Magnetic interference
GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Caution required
Handle with care. Neodymium magnets attract from a long distance and snap with massive power, often quicker than you can react.
Do not overheat magnets
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Combustion hazard
Dust generated during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Nickel coating and allergies
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease working with magnets and wear gloves.
Cards and drives
Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
