Pros and cons of neodymium magnets.
Strengths
- They have stable power, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are distinguished by exceptionally resistant to loss of magnetic properties caused by magnetic disturbances,
- By applying a decorative coating of gold, the element gains an nice look,
- Magnets have very high magnetic induction on the outer side,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- In view of the potential of accurate molding and adaptation to individualized projects, neodymium magnets can be modeled in a variety of shapes and sizes, which increases their versatility,
- Huge importance in advanced technology sectors – they are commonly used in computer drives, electric motors, precision medical tools, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in small systems
Cons
- To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Limited ability of producing nuts in the magnet and complex forms - preferred is casing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child health protection. Additionally, small elements of these magnets can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a plate made of low-carbon steel, acting as a ideal flux conductor
- with a cross-section minimum 10 mm
- with a plane free of scratches
- with total lack of distance (without paint)
- during pulling in a direction perpendicular to the plane
- in neutral thermal conditions
Key elements affecting lifting force
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin plate does not close the flux, causing part of the flux to be escaped into the air.
- Metal type – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Safe handling of neodymium magnets
Mechanical processing
Combustion risk: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
Protect data
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Phone sensors
Navigation devices and mobile phones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Eye protection
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Avoid contact if allergic
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease working with magnets and wear gloves.
Medical interference
For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Keep away from children
Absolutely store magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are fatal.
Pinching danger
Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Respect the power
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Maximum temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
