Pros and cons of Nd2Fe14B magnets.
Pros
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the metallic finish of nickel, the element becomes visually attractive,
- Magnetic induction on the working layer of the magnet turns out to be extremely intense,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- In view of the possibility of free shaping and customization to individualized needs, NdFeB magnets can be produced in a variety of forms and dimensions, which increases their versatility,
- Huge importance in high-tech industry – they are commonly used in mass storage devices, electromotive mechanisms, advanced medical instruments, as well as technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Due to limitations in creating threads and complicated forms in magnets, we propose using casing - magnetic holder.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- with the application of a yoke made of special test steel, guaranteeing maximum field concentration
- with a thickness minimum 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was assessed using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
Safe handling of NdFeB magnets
Electronic devices
Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Handling rules
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Protective goggles
Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets leads to them cracking into shards.
Medical interference
People with a ICD should maintain an large gap from magnets. The magnetic field can stop the operation of the life-saving device.
Skin irritation risks
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop handling magnets and wear gloves.
No play value
NdFeB magnets are not suitable for play. Eating a few magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates urgent medical intervention.
Hand protection
Risk of injury: The attraction force is so great that it can cause hematomas, crushing, and broken bones. Use thick gloves.
Machining danger
Powder created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
GPS Danger
Remember: neodymium magnets produce a field that confuses sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Thermal limits
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
