Strengths and weaknesses of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They possess excellent resistance to magnetism drop as a result of opposing magnetic fields,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- In view of the possibility of precise forming and customization to individualized needs, neodymium magnets can be manufactured in a variety of shapes and sizes, which makes them more universal,
- Wide application in innovative solutions – they are used in data components, electric motors, diagnostic systems, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves 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 force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing nuts in the magnet and complicated shapes - recommended is casing - mounting mechanism.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a base made of low-carbon steel, functioning as a circuit closing element
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by lack of roughness
- with direct contact (without impurities)
- for force applied at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Direction of force – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin steel does not accept the full field, causing part of the power to be escaped into the air.
- Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic permeability and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
GPS and phone interference
GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Serious injuries
Danger of trauma: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Shattering risk
NdFeB magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets will cause them cracking into small pieces.
Keep away from computers
Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Allergy Warning
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.
Handling rules
Handle magnets consciously. Their huge power can surprise even professionals. Plan your moves and respect their power.
Thermal limits
Control the heat. Heating the magnet to high heat will ruin its magnetic structure and pulling force.
No play value
Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Store away from children and animals.
Fire risk
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Danger to pacemakers
Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
