Advantages as well as disadvantages of rare earth magnets.
Benefits
- They do not lose magnetism, even during nearly ten years – the drop in lifting capacity is only ~1% (according to tests),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the reflective layer of silver, the element is aesthetically pleasing,
- Magnets are characterized by exceptionally strong magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of custom machining as well as adapting to atypical applications,
- Key role in electronics industry – they serve a role in mass storage devices, electric drive systems, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in small systems
Cons
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these products can complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- on a base made of structural steel, optimally conducting the magnetic flux
- with a thickness of at least 10 mm
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at temperature room level
Practical lifting capacity: influencing factors
- Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Material type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Power loss in heat
Avoid heat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Finger safety
Danger of trauma: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Product not for children
Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of kids and pets.
Protective goggles
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Allergy Warning
Some people experience a hypersensitivity to nickel, which is the standard coating for neodymium magnets. Frequent touching can result in a rash. We recommend use safety gloves.
Threat to electronics
Do not bring magnets near a purse, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Health Danger
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Handling rules
Handle magnets with awareness. Their powerful strength can shock even experienced users. Be vigilant and do not underestimate their force.
Dust explosion hazard
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.
GPS Danger
An intense magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a device to avoid damaging the sensors.
