Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They retain magnetic properties for nearly 10 years – the loss is just ~1% (according to analyses),
- Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external magnetic fields,
- In other words, due to the aesthetic layer of gold, the element looks attractive,
- Magnetic induction on the working part of the magnet remains exceptional,
- 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 ability of precise shaping and adaptation to specialized solutions, NdFeB magnets can be modeled in a broad palette of geometric configurations, which makes them more universal,
- Significant place in modern industrial fields – they are commonly used in magnetic memories, drive modules, diagnostic systems, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating threads and complicated forms in magnets, we recommend using casing - magnetic mount.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets can be a barrier,
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- using a sheet made of low-carbon steel, serving as a magnetic yoke
- with a cross-section no less than 10 mm
- with an polished touching surface
- without any clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – too thin sheet causes magnetic saturation, causing part of the power to be escaped to the other side.
- Plate material – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Allergic reactions
A percentage of the population experience a sensitization to nickel, which is the standard coating for NdFeB magnets. Prolonged contact can result in a rash. It is best to wear safety gloves.
Safe distance
Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.
Medical implants
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Crushing risk
Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, crushing everything in their path. Be careful!
Choking Hazard
Absolutely store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are life-threatening.
Operating temperature
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and strength.
Immense force
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
GPS and phone interference
An intense magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.
Mechanical processing
Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Risk of cracking
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets leads to them shattering into small pieces.
