Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
- They maintain their magnetic properties even under strong external field,
- By applying a shiny layer of nickel, the element has an professional look,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Considering the option of accurate forming and adaptation to unique needs, magnetic components can be modeled in a variety of geometric configurations, which makes them more universal,
- Wide application in modern technologies – they are used in hard drives, brushless drives, medical equipment, as well as technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of creating nuts in the magnet and complicated shapes - preferred is a housing - magnet mounting.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Additionally, tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- using a base made of mild steel, serving as a ideal flux conductor
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a plane free of scratches
- under conditions of no distance (surface-to-surface)
- under axial application of breakaway force (90-degree angle)
- in stable room temperature
Key elements affecting lifting force
- Distance (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the power to be lost into the air.
- Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Smoothness – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.
H&S for magnets
Serious injuries
Risk of injury: The pulling power is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
Warning for allergy sufferers
A percentage of the population suffer from a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching may cause skin redness. It is best to wear protective gloves.
Magnetic interference
Remember: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.
Heat warning
Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Safe operation
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Implant safety
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.
This is not a toy
Always store magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are life-threatening.
Magnetic media
Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
Magnets are brittle
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.
Combustion hazard
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
