Other proposals
Advantages as well as disadvantages of rare earth magnets.
Pros
- Their magnetic field is durable, and after around ten years it drops only by ~1% (theoretically),
- They do not lose their magnetic properties even under close interference source,
- Thanks to the reflective finish, the plating of nickel, gold, or silver-plated gives an elegant 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 precise machining and adapting to precise needs,
- Versatile presence in electronics industry – they are commonly used in data components, electric drive systems, advanced medical instruments, also modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical after entering the body.
- Due to complex production process, their price is higher than average,
Pull force analysis
Magnetic strength at its maximum – what affects it?
- with the application of a sheet made of special test steel, ensuring full magnetic saturation
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- under axial force direction (90-degree angle)
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be lost to the other side.
- Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Skin irritation risks
Some people suffer from a sensitization to Ni, which is the common plating for NdFeB magnets. Frequent touching may cause an allergic reaction. We strongly advise wear protective gloves.
Permanent damage
Do not overheat. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).
Swallowing risk
These products are not toys. Eating a few magnets may result in them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.
Precision electronics
Note: neodymium magnets produce a field that confuses sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
Hand protection
Large magnets can smash fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
Electronic hazard
Do not bring magnets near a purse, laptop, or TV. The magnetism can destroy these devices and erase data from cards.
Caution required
Use magnets consciously. Their huge power can shock even professionals. Stay alert and do not underestimate their power.
Magnets are brittle
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Medical implants
Medical warning: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Flammability
Powder produced during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
