Advantages and disadvantages of rare earth magnets.
Advantages
- They retain full power for nearly 10 years – the drop is just ~1% (according to analyses),
- Neodymium magnets are highly resistant to magnetic field loss caused by magnetic disturbances,
- By applying a decorative coating of silver, the element presents an nice look,
- Magnetic induction on the top side of the magnet turns out to be 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...
- Possibility of custom shaping as well as modifying to atypical needs,
- Huge importance in advanced technology sectors – they are utilized in mass storage devices, electric drive systems, medical devices, as well as complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating threads and complex forms in magnets, we recommend using a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small components of these products can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a block made of structural steel, effectively closing the magnetic field
- whose thickness is min. 10 mm
- characterized by even structure
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Gap (between the magnet and the plate), because even a very small distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Material type – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Medical implants
Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Phone sensors
GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
Immense force
Handle with care. Neodymium magnets attract from a distance and snap with massive power, often faster than you can react.
Maximum temperature
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Swallowing risk
Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Keep out of reach of kids and pets.
Warning for allergy sufferers
Certain individuals suffer from a contact allergy to nickel, which is the common plating for neodymium magnets. Extended handling might lead to a rash. We strongly advise use protective gloves.
Keep away from computers
Intense magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
Beware of splinters
Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them breaking into shards.
Do not drill into magnets
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Hand protection
Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
