Advantages and disadvantages of rare earth magnets.
Advantages
- They do not lose strength, even during approximately 10 years – the drop in power is only ~1% (based on measurements),
- They do not lose their magnetic properties even under external field action,
- A magnet with a metallic silver surface has an effective appearance,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which allows for strong attraction,
- 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 accurate forming as well as adjusting to defined conditions,
- Fundamental importance in future technologies – they are utilized in data components, brushless drives, medical equipment, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complicated forms in magnets, we recommend using a housing - magnetic mount.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Highest magnetic holding force – what contributes to it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- whose thickness reaches at least 10 mm
- characterized by lack of roughness
- without any air gap between the magnet and steel
- under axial force vector (90-degree angle)
- in temp. approx. 20°C
Key elements affecting lifting force
- Clearance – the presence of any layer (rust, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
- Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet and the plate lowers the holding force.
Safe handling of neodymium magnets
Avoid contact if allergic
It is widely known that nickel (the usual finish) is a strong allergen. If you have an allergy, prevent direct skin contact and select versions in plastic housing.
Heat warning
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Data carriers
Do not bring magnets near a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Medical implants
Individuals with a pacemaker must maintain an large gap from magnets. The magnetism can disrupt the functioning of the implant.
Handling guide
Use magnets consciously. Their immense force can surprise even professionals. Stay alert and do not underestimate their force.
No play value
Strictly keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are tragic.
Compass and GPS
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Combustion hazard
Powder created during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Magnets are brittle
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Finger safety
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!
