Strengths as well as weaknesses of neodymium magnets.
Strengths
- They retain attractive force for nearly ten years – the drop is just ~1% (in theory),
- They possess excellent resistance to magnetic field loss as a result of opposing magnetic fields,
- Thanks to the reflective finish, the surface of nickel, gold-plated, or silver-plated gives an professional appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of custom machining and optimizing to specific requirements,
- Fundamental importance in high-tech industry – they are used in HDD drives, electric motors, advanced medical instruments, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in miniature devices
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to 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.
- We suggest a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
- Potential hazard 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 magnets can complicate diagnosis medical when they are in the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- with the contact of a sheet made of special test steel, ensuring full magnetic saturation
- with a cross-section no less than 10 mm
- with an ground contact surface
- with direct contact (no coatings)
- for force applied at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be wasted to the other side.
- Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Powerful field
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.
Do not give to children
These products are not intended for children. Eating a few magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
Keep away from computers
Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Warning for allergy sufferers
Some people suffer from a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching might lead to skin redness. We strongly advise use protective gloves.
Health Danger
For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
Operating temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Bone fractures
Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Magnetic interference
A powerful magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to avoid damaging the sensors.
Material brittleness
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Do not drill into magnets
Dust created during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
