Other proposals
Strengths as well as weaknesses of rare earth magnets.
Advantages
- They retain full power for around 10 years – the drop is just ~1% (based on simulations),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- A magnet with a shiny gold surface is more attractive,
- Magnetic induction on the working part of the magnet remains extremely intense,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Possibility of custom shaping and modifying to atypical requirements,
- Significant place in high-tech industry – they are used in data components, electric motors, medical equipment, as well as other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex forms in magnets, we propose using casing - magnetic mechanism.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a cross-section of at least 10 mm
- characterized by smoothness
- under conditions of no distance (surface-to-surface)
- under vertical force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Air gap (betwixt the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin steel does not close the flux, causing part of the power to be lost to the other side.
- Plate material – low-carbon steel attracts best. Alloy admixtures decrease magnetic permeability and holding force.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Cards and drives
Data protection: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
This is not a toy
Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Store away from kids and pets.
Keep away from electronics
A powerful magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Maintain magnets near a device to prevent damaging the sensors.
Do not underestimate power
Handle magnets with awareness. Their powerful strength can surprise even experienced users. Plan your moves and respect their power.
Permanent damage
Watch the temperature. Heating the magnet to high heat will destroy its properties and strength.
Hand protection
Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!
Fragile material
NdFeB magnets are ceramic materials, meaning they are very brittle. Collision of two magnets leads to them cracking into shards.
Machining danger
Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Health Danger
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, immediately stop handling magnets and wear gloves.
