Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They retain magnetic properties for almost 10 years – the drop is just ~1% (according to analyses),
- Magnets very well protect themselves against demagnetization caused by external fields,
- Thanks to the elegant finish, the layer of nickel, gold, or silver-plated gives an elegant appearance,
- Magnetic induction on the working part of the magnet remains exceptional,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the ability of flexible molding and customization to custom solutions, magnetic components can be created in a broad palette of shapes and sizes, which expands the range of possible applications,
- Fundamental importance in modern industrial fields – they find application in data components, electromotive mechanisms, diagnostic systems, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its 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, as well as 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 cover - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price exceeds standard values,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section no less than 10 mm
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- under axial application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Distance – existence of any layer (rust, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy admixtures lower magnetic properties and holding force.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was assessed by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Swallowing risk
NdFeB magnets are not toys. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates immediate surgery.
Dust explosion hazard
Dust produced during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Warning for heart patients
Patients with a heart stimulator should maintain an large gap from magnets. The magnetism can stop the operation of the implant.
Pinching danger
Big blocks can crush fingers in a fraction of a second. Never put your hand between two strong magnets.
Magnetic media
Data protection: Strong magnets can damage data carriers and sensitive devices (heart implants, medical aids, mechanical watches).
Do not overheat magnets
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Warning for allergy sufferers
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Shattering risk
Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets will cause them breaking into shards.
Handling rules
Handle magnets consciously. Their immense force can surprise even experienced users. Be vigilant and respect their force.
Threat to navigation
GPS units and mobile phones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
