Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for around 10 years – the drop is just ~1% (based on simulations),
- Neodymium magnets are distinguished by highly resistant to magnetic field loss caused by external interference,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working part of the magnet turns out to be impressive,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in constructing and the capacity to adapt to client solutions,
- Key role in future technologies – they serve a role in hard drives, electric motors, advanced medical instruments, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We suggest casing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these magnets are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a base made of mild steel, serving as a magnetic yoke
- with a cross-section of at least 10 mm
- with a plane perfectly flat
- with total lack of distance (without coatings)
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust 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.
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the flux to be wasted into the air.
- Metal type – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
H&S for magnets
Serious injuries
Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Electronic devices
Do not bring magnets near a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
Fire warning
Dust generated during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Metal Allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease working with magnets and use protective gear.
Do not underestimate power
Use magnets consciously. Their immense force can shock even professionals. Stay alert and respect their power.
Compass and GPS
A strong magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a smartphone to prevent damaging the sensors.
Protective goggles
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them breaking into shards.
Heat warning
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Swallowing risk
Strictly keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are very dangerous.
Medical interference
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
