Pros and cons of neodymium magnets.
Strengths
- They retain magnetic properties for around 10 years – the drop is just ~1% (based on simulations),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- A magnet with a shiny gold surface is more attractive,
- Magnets exhibit exceptionally strong magnetic induction on the working surface,
- 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 exact modeling and adjusting to precise conditions,
- Fundamental importance in future technologies – they are commonly used in mass storage devices, electromotive mechanisms, diagnostic systems, as well as complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as 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 start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited ability of making nuts in the magnet and complex forms - recommended is a housing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small components of these magnets can complicate diagnosis medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- using a plate made of mild steel, functioning as a ideal flux conductor
- with a thickness minimum 10 mm
- with a plane perfectly flat
- with direct contact (without paint)
- for force applied at a right angle (pull-off, not shear)
- at standard ambient temperature
What influences lifting capacity in practice
- Space between surfaces – every millimeter of separation (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 has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.
Safe handling of NdFeB magnets
Safe distance
Intense magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Threat to navigation
Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Skin irritation risks
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.
Fragile material
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Health Danger
Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
Respect the power
Handle magnets with awareness. Their immense force can shock even professionals. Stay alert and respect their power.
Thermal limits
Avoid heat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Swallowing risk
Neodymium magnets are not intended for children. Swallowing multiple magnets can lead to them attracting across intestines, which constitutes a severe health hazard and necessitates immediate surgery.
Crushing force
Danger of trauma: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Mechanical processing
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
