Strengths and weaknesses of rare earth magnets.
Strengths
- Their power remains stable, and after approximately 10 years it drops only by ~1% (according to research),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a metallic silver surface is more attractive,
- Magnets are characterized by huge magnetic induction on the outer layer,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- In view of the option of accurate forming and customization to specialized needs, neodymium magnets can be manufactured in a wide range of forms and dimensions, which expands the range of possible applications,
- Versatile presence in modern technologies – they find application in mass storage devices, electric motors, diagnostic systems, as well as industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and 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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of making threads in the magnet and complex forms - preferred is cover - magnet mounting.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small components of these products can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a sheet made of high-permeability steel, serving as a magnetic yoke
- whose thickness is min. 10 mm
- with a surface cleaned and smooth
- with total lack of distance (without coatings)
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Temperature – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Medical implants
Individuals with a heart stimulator have to maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Precision electronics
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Swallowing risk
Neodymium magnets are not suitable for play. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates urgent medical intervention.
Safe distance
Do not bring magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease working with magnets and use protective gear.
Crushing force
Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Do not drill into magnets
Dust produced during machining of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Magnets are brittle
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them breaking into shards.
Demagnetization risk
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Caution required
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
