Strengths and weaknesses of rare earth magnets.
Benefits
- They retain magnetic properties for nearly 10 years – the drop is just ~1% (based on simulations),
- Magnets effectively resist against loss of magnetization caused by external fields,
- In other words, due to the aesthetic finish of nickel, the element is aesthetically pleasing,
- Magnetic induction on the working part of the magnet turns out to be exceptional,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to versatility in constructing and the capacity to modify to complex applications,
- Universal use in modern industrial fields – they serve a role in hard drives, electric drive systems, advanced medical instruments, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic holder, due to difficulties in producing threads inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these products can be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price is higher than average,
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an ground contact surface
- with total lack of distance (no paint)
- during detachment in a direction vertical to the mounting surface
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin sheet does not close the flux, causing part of the power to be lost into the air.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may attract less.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the holding force.
Precautions when working with neodymium magnets
Implant safety
Individuals with a pacemaker must keep an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Power loss in heat
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Bodily injuries
Large magnets can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
Do not underestimate power
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Product not for children
NdFeB magnets are not toys. Swallowing multiple magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.
Impact on smartphones
GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Magnetic media
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Combustion hazard
Machining of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Beware of splinters
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them cracking into shards.
Sensitization to coating
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
