Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They do not lose magnetism, even after approximately ten years – the drop in strength is only ~1% (theoretically),
- Neodymium magnets remain extremely resistant to loss of magnetic properties caused by magnetic disturbances,
- Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an clean appearance,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of exact forming as well as modifying to atypical conditions,
- Fundamental importance in modern technologies – they are commonly used in hard drives, electric drive systems, medical equipment, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in creating nuts and complicated forms in magnets, we propose using cover - magnetic mount.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum holding power of the magnet – what affects it?
- with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- with an ground touching surface
- under conditions of ideal adhesion (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer 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 holds much less (often approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Material type – the best choice is high-permeability steel. Hardened steels may attract less.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Heat sensitivity
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Magnet fragility
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them breaking into shards.
Warning for allergy sufferers
A percentage of the population experience a hypersensitivity to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to an allergic reaction. It is best to use protective gloves.
Serious injuries
Protect your hands. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Threat to navigation
Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
Flammability
Powder created during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Medical interference
People with a heart stimulator have to maintain an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Danger to the youngest
NdFeB magnets are not intended for children. Eating several magnets can lead to them attracting across intestines, which constitutes a severe health hazard and requires urgent medical intervention.
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Protect data
Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
