Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- Magnets perfectly defend themselves against loss of magnetization caused by ambient magnetic noise,
- By applying a smooth coating of gold, the element presents an aesthetic look,
- Neodymium magnets deliver maximum magnetic induction on a small surface, which increases force concentration,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- In view of the option of free shaping and adaptation to specialized solutions, magnetic components can be produced in a variety of shapes and sizes, which increases their versatility,
- Significant place in electronics industry – they are used in HDD drives, brushless drives, medical equipment, and other advanced devices.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Disadvantages
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complex forms in magnets, we recommend using casing - magnetic mount.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- on a plate made of structural steel, effectively closing the magnetic flux
- whose thickness equals approx. 10 mm
- with a plane free of scratches
- without the slightest insulating layer between the magnet and steel
- during detachment in a direction vertical to the mounting surface
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Air gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.
Warnings
Adults only
Product intended for adults. Small elements pose a choking risk, causing severe trauma. Store away from children and animals.
Finger safety
Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!
Beware of splinters
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Danger to pacemakers
Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
Dust explosion hazard
Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Magnetic media
Data protection: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Do not underestimate power
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Compass and GPS
Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Sensitization to coating
Studies show that nickel (the usual finish) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or opt for versions in plastic housing.
Heat sensitivity
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
