Pros and cons of Nd2Fe14B magnets.
Strengths
- They retain attractive force for around ten years – the loss is just ~1% (according to analyses),
- Magnets very well resist against demagnetization caused by foreign field sources,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets ensure maximum magnetic induction on a their surface, which increases force concentration,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Possibility of individual machining as well as modifying to individual requirements,
- Huge importance in advanced technology sectors – they are utilized in HDD drives, electric drive systems, diagnostic systems, also modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and 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 as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complex shapes - recommended is casing - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a base made of structural steel, effectively closing the magnetic flux
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a plane free of scratches
- without any clearance between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at standard ambient temperature
What influences lifting capacity in practice
- Air gap (between the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Steel type – mild steel attracts best. Alloy steels decrease magnetic properties and holding force.
- Plate texture – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the holding force.
Precautions when working with neodymium magnets
Electronic hazard
Do not bring magnets near a wallet, laptop, or screen. The magnetic field can destroy these devices and wipe information from cards.
Permanent damage
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Warning for heart patients
Warning for patients: Powerful magnets affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
Bone fractures
Protect your hands. Two large magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Keep away from electronics
Remember: neodymium magnets generate a field that disrupts precision electronics. Maintain a separation from your phone, device, and GPS.
Nickel coating and allergies
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease handling magnets and use protective gear.
Do not underestimate power
Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can react.
Flammability
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Fragile material
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.
Choking Hazard
These products are not toys. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.
