Advantages and disadvantages of neodymium magnets.
Pros
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- Magnets perfectly protect themselves against demagnetization caused by foreign field sources,
- In other words, due to the shiny surface of gold, the element is aesthetically pleasing,
- Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of exact modeling as well as adapting to precise requirements,
- Significant place in high-tech industry – they are used in data components, drive modules, medical equipment, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 very resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of high-permeability steel, acting as a magnetic yoke
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ground contact surface
- with zero gap (no coatings)
- for force acting at a right angle (in the magnet axis)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Gap (betwixt the magnet and the plate), because even a very small distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic properties and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was determined using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Protect data
Powerful magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Precision electronics
Navigation devices and smartphones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Crushing risk
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Caution required
Exercise caution. Neodymium magnets act from a long distance and connect with massive power, often faster than you can move away.
Avoid contact if allergic
Some people have a hypersensitivity to Ni, which is the common plating for neodymium magnets. Extended handling may cause dermatitis. It is best to use protective gloves.
No play value
Adult use only. Small elements can be swallowed, leading to intestinal necrosis. Store out of reach of children and animals.
Danger to pacemakers
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Flammability
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Risk of cracking
Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets will cause them cracking into small pieces.
Heat sensitivity
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
