Strengths as well as weaknesses of neodymium magnets.
Strengths
- Their power remains stable, and after around 10 years it drops only by ~1% (according to research),
- Neodymium magnets prove to be highly resistant to magnetic field loss caused by external field sources,
- By covering with a reflective layer of nickel, the element has an proper look,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of detailed modeling and adjusting to specific needs,
- Versatile presence in future technologies – they find application in HDD drives, electric motors, precision medical tools, also technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making threads in the magnet and complicated shapes - preferred is a housing - mounting mechanism.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these products can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Highest magnetic holding force – what contributes to it?
- using a base made of low-carbon steel, serving as a circuit closing element
- with a cross-section minimum 10 mm
- characterized by even structure
- without any clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
What influences lifting capacity in practice
- Gap (betwixt the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of NdFeB magnets
Danger to pacemakers
People with a pacemaker have to maintain an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.
Impact on smartphones
A powerful magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Do not bring magnets near a device to avoid breaking the sensors.
Flammability
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
Heat sensitivity
Watch the temperature. Exposing the magnet to high heat will ruin its properties and pulling force.
Magnets are brittle
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them cracking into small pieces.
Danger to the youngest
NdFeB magnets are not intended for children. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
Conscious usage
Be careful. Rare earth magnets act from a distance and connect with huge force, often quicker than you can react.
Allergy Warning
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness happens, cease handling magnets and wear gloves.
Serious injuries
Big blocks can crush fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Magnetic media
Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
