Strengths as well as weaknesses of neodymium magnets.
Pros
- Their strength is maintained, and after around 10 years it drops only by ~1% (according to research),
- They maintain their magnetic properties even under close interference source,
- A magnet with a metallic silver surface has better aesthetics,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Considering the ability of precise forming and adaptation to specialized needs, NdFeB magnets can be modeled in a broad palette of shapes and sizes, which increases their versatility,
- Wide application in advanced technology sectors – they are utilized in data components, electric drive systems, precision medical tools, and modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We recommend a housing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- using a base made of low-carbon steel, serving as a magnetic yoke
- whose thickness reaches at least 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Gap (betwixt the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be lost into the air.
- Chemical composition of the base – low-carbon steel gives the best results. Higher carbon content lower magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under shearing force the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Finger safety
Risk of injury: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Swallowing risk
Neodymium magnets are not intended for children. Eating several magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates urgent medical intervention.
Sensitization to coating
Certain individuals have a sensitization to nickel, which is the standard coating for NdFeB magnets. Prolonged contact might lead to skin redness. We strongly advise wear safety gloves.
Maximum temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Powerful field
Handle with care. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can react.
GPS Danger
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Pacemakers
Warning for patients: Powerful magnets affect medical devices. Maintain at least 30 cm distance or ask another person to work with the magnets.
Do not drill into magnets
Dust created during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Magnet fragility
Neodymium magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets leads to them shattering into shards.
Protect data
Data protection: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
