Advantages and disadvantages of rare earth magnets.
Strengths
- They retain magnetic properties for almost 10 years – the drop is just ~1% (in theory),
- Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by magnetic disturbances,
- A magnet with a smooth gold surface has an effective appearance,
- Neodymium magnets create maximum magnetic induction on a small surface, which increases force concentration,
- 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 freedom in designing and the capacity to modify to complex applications,
- Huge importance in innovative solutions – they are commonly used in mass storage devices, motor assemblies, medical devices, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in power. 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
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited possibility of making threads in the magnet and complicated forms - recommended is casing - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Additionally, tiny parts of these products are able to complicate diagnosis medical after entering the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- on a block made of structural steel, optimally conducting the magnetic field
- with a cross-section no less than 10 mm
- with a plane cleaned and smooth
- with total lack of distance (without impurities)
- during pulling in a direction vertical to the mounting surface
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Distance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the load capacity.
Warnings
Implant safety
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Skin irritation risks
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease handling magnets and use protective gear.
Material brittleness
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Electronic hazard
Powerful magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
This is not a toy
Strictly store magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are very dangerous.
Dust is flammable
Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Magnetic interference
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Maximum temperature
Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.
Crushing force
Danger of trauma: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Powerful field
Use magnets consciously. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their force.
