Pros and cons of rare earth magnets.
Advantages
- They have stable power, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
- Magnets very well resist against demagnetization caused by ambient magnetic noise,
- By using a shiny coating of nickel, the element presents an nice look,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Thanks to flexibility in constructing and the ability to customize to complex applications,
- Key role in future technologies – they serve a role in computer drives, drive modules, medical equipment, also other advanced devices.
- 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 protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We recommend cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these magnets are able to complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a base made of high-permeability steel, serving as a magnetic yoke
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- without any clearance between the magnet and steel
- under axial application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Safe handling of NdFeB magnets
Operating temperature
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
Bodily injuries
Mind your fingers. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Be careful!
Respect the power
Handle magnets consciously. Their huge power can shock even professionals. Stay alert and do not underestimate their power.
Threat to electronics
Do not bring magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Machining danger
Dust generated during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Keep away from electronics
Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Product not for children
Adult use only. Small elements can be swallowed, leading to serious injuries. Keep away from kids and pets.
Beware of splinters
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.
Pacemakers
People with a ICD should keep an large gap from magnets. The magnetism can interfere with the functioning of the life-saving device.
Warning for allergy sufferers
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease handling magnets and use protective gear.
