Pros as well as cons of neodymium magnets.
Pros
- They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- They maintain their magnetic properties even under external field action,
- In other words, due to the aesthetic layer of gold, the element becomes visually attractive,
- Magnetic induction on the working layer of the magnet turns out to be strong,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
- Due to the ability of free shaping and adaptation to custom projects, neodymium magnets can be produced in a variety of shapes and sizes, which expands the range of possible applications,
- Huge importance in electronics industry – they serve a role in HDD drives, drive modules, medical equipment, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in miniature devices
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength 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
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension is min. 10 mm
- with a surface cleaned and smooth
- without any insulating layer between the magnet and steel
- during detachment in a direction perpendicular to the plane
- at temperature room level
Practical aspects of lifting capacity – factors
- Distance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Nickel allergy
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, prevent direct skin contact or opt for coated magnets.
Danger to pacemakers
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Respect the power
Exercise caution. Rare earth magnets act from a distance and connect with huge force, often faster than you can move away.
Risk of cracking
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Dust is flammable
Dust generated during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Threat to navigation
A powerful magnetic field interferes with the operation of compasses in smartphones and navigation systems. Do not bring magnets close to a device to avoid breaking the sensors.
Finger safety
Large magnets can smash fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
This is not a toy
These products are not intended for children. Eating several magnets may result in them pinching intestinal walls, which poses a direct threat to life and necessitates urgent medical intervention.
Operating temperature
Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Cards and drives
Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.
