Advantages and disadvantages of neodymium magnets.
Advantages
- They retain full power for around 10 years – the loss is just ~1% (based on simulations),
- They maintain their magnetic properties even under strong external field,
- Thanks to the elegant finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an modern appearance,
- Magnetic induction on the top side of the magnet is impressive,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
- Possibility of precise modeling and modifying to complex requirements,
- Huge importance in modern technologies – they are commonly used in magnetic memories, electric drive systems, advanced medical instruments, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets lose their force 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
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness equals approx. 10 mm
- with an polished contact surface
- without any clearance between the magnet and steel
- during detachment in a direction vertical to the plane
- at room temperature
Lifting capacity in real conditions – factors
- Distance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Fire warning
Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.
Allergy Warning
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and wear gloves.
Keep away from electronics
GPS units and mobile phones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
No play value
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them attracting across intestines, which constitutes a critical condition and requires immediate surgery.
Health Danger
People with a heart stimulator should keep an absolute distance from magnets. The magnetic field can stop the functioning of the implant.
Threat to electronics
Avoid bringing magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Finger safety
Danger of trauma: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Permanent damage
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Magnet fragility
NdFeB magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets leads to them shattering into shards.
Do not underestimate power
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
