Strengths as well as weaknesses of rare earth magnets.
Advantages
- They do not lose magnetism, even during approximately 10 years – the drop in strength is only ~1% (according to tests),
- They show high resistance to demagnetization induced by external field influence,
- A magnet with a smooth silver surface has better aesthetics,
- Neodymium magnets ensure maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of detailed modeling as well as adapting to precise requirements,
- Key role in electronics industry – they serve a role in computer drives, motor assemblies, advanced medical instruments, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complicated shapes in magnets, we propose using casing - magnetic mount.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these devices can complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- using a plate made of low-carbon steel, serving as a ideal flux conductor
- whose thickness is min. 10 mm
- with a surface cleaned and smooth
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Allergy Warning
Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, immediately stop handling magnets and wear gloves.
Adults only
Product intended for adults. Small elements pose a choking risk, leading to intestinal necrosis. Keep away from kids and pets.
Fragile material
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Crushing force
Watch your fingers. Two large magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!
Fire warning
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Operating temperature
Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
Respect the power
Use magnets with awareness. Their immense force can shock even experienced users. Be vigilant and do not underestimate their power.
Medical implants
Patients with a ICD must maintain an absolute distance from magnets. The magnetism can stop the operation of the implant.
Safe distance
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Phone sensors
Note: neodymium magnets produce a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and navigation systems.
