Strengths and weaknesses of neodymium magnets.
Strengths
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by external disturbances,
- The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working layer of the magnet remains very high,
- 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...
- Due to the possibility of precise molding and customization to specialized solutions, neodymium magnets can be manufactured in a variety of shapes and sizes, which expands the range of possible applications,
- Versatile presence in innovative solutions – they are commonly used in hard drives, motor assemblies, medical devices, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets decrease 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 durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in creating nuts and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices can complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- on a block made of mild steel, optimally conducting the magnetic field
- with a thickness of at least 10 mm
- with a plane perfectly flat
- without any air gap between the magnet and steel
- under axial force vector (90-degree angle)
- in stable room temperature
Key elements affecting lifting force
- Air gap (betwixt the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, rust or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Safety rules for work with NdFeB magnets
Hand protection
Big blocks can crush fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Do not overheat magnets
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Metal Allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, cease working with magnets and use protective gear.
Data carriers
Very strong magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Risk of cracking
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Phone sensors
Navigation devices and smartphones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Flammability
Dust generated during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Medical interference
Patients with a ICD must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the life-saving device.
Keep away from children
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep out of reach of kids and pets.
Caution required
Exercise caution. Neodymium magnets act from a long distance and snap with huge force, often faster than you can move away.
