Strengths as well as weaknesses of neodymium magnets.
Advantages
- They retain magnetic properties for around 10 years – the drop is just ~1% (in theory),
- Magnets perfectly protect themselves against demagnetization caused by ambient magnetic noise,
- In other words, due to the glossy finish of nickel, the element is aesthetically pleasing,
- Magnets possess excellent magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of individual machining and modifying to individual needs,
- Versatile presence in high-tech industry – they are commonly used in HDD drives, drive modules, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. 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
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing nuts and complex forms in magnets, we propose using cover - magnetic mechanism.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of high-permeability steel, serving as a ideal flux conductor
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by smoothness
- with zero gap (no coatings)
- under vertical application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of any layer (rust, dirt, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel type – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and holding force.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Compass and GPS
Navigation devices and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Eye protection
Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets will cause them breaking into small pieces.
Do not underestimate power
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Warning for allergy sufferers
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact or opt for encased magnets.
Electronic hazard
Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Pinching danger
Danger of trauma: The attraction force is so immense that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
Keep away from children
NdFeB magnets are not intended for children. Eating a few magnets may result in them attracting across intestines, which constitutes a critical condition and requires urgent medical intervention.
Implant safety
Warning for patients: Powerful magnets affect medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
Do not overheat magnets
Control the heat. Heating the magnet to high heat will ruin its properties and strength.
Fire warning
Dust produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
