Pros and cons of rare earth magnets.
Strengths
- They do not lose power, even after around 10 years – the drop in power is only ~1% (based on measurements),
- Neodymium magnets remain extremely resistant to magnetic field loss caused by external field sources,
- A magnet with a metallic gold surface has an effective appearance,
- Magnets are characterized by very high magnetic induction on the outer side,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of custom modeling as well as optimizing to defined needs,
- Key role in advanced technology sectors – they serve a role in HDD drives, electric motors, precision medical tools, and multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- 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 as well as corrosion.
- We suggest casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small elements of these devices are able to be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum lifting force for a neodymium magnet – what affects it?
- on a base made of structural steel, optimally conducting the magnetic flux
- with a thickness of at least 10 mm
- characterized by even structure
- with total lack of distance (no impurities)
- during detachment in a direction vertical to the mounting surface
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Clearance – the presence of any layer (paint, dirt, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the power to be wasted to the other side.
- Chemical composition of the base – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and holding force.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the load capacity.
Warnings
Data carriers
Do not bring magnets near a purse, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Conscious usage
Exercise caution. Rare earth magnets act from a distance and connect with huge force, often quicker than you can react.
Impact on smartphones
Note: neodymium magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
Hand protection
Mind your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Eye protection
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Avoid contact if allergic
Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, avoid direct skin contact or choose coated magnets.
Machining danger
Machining of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Medical interference
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Heat sensitivity
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Product not for children
Adult use only. Small elements pose a choking risk, causing intestinal necrosis. Keep away from kids and pets.
