Advantages and disadvantages of rare earth magnets.
Advantages
- Their strength is durable, and after around 10 years it decreases only by ~1% (theoretically),
- Magnets very well resist against loss of magnetization caused by ambient magnetic noise,
- By covering with a smooth layer of gold, the element presents an professional look,
- The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Possibility of custom creating as well as adapting to individual applications,
- Significant place in high-tech industry – they are commonly used in HDD drives, electromotive mechanisms, medical equipment, as well as other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- using a base made of mild steel, functioning as a magnetic yoke
- whose thickness reaches at least 10 mm
- characterized by even structure
- with direct contact (without paint)
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the plate), because even a microscopic distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Metal type – different alloys attracts identically. High carbon content weaken the attraction effect.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Metal Allergy
Studies show that the nickel plating (the usual finish) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands and choose encased magnets.
Do not give to children
Strictly store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are life-threatening.
Fire warning
Fire warning: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Keep away from electronics
A strong magnetic field disrupts the operation of compasses in phones and GPS navigation. Do not bring magnets close to a device to prevent breaking the sensors.
Finger safety
Pinching hazard: The attraction force is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
Do not overheat magnets
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and strength.
Eye protection
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.
Implant safety
Patients with a ICD have to maintain an absolute distance from magnets. The magnetism can interfere with the operation of the life-saving device.
Respect the power
Handle magnets with awareness. Their immense force can surprise even professionals. Be vigilant and respect their force.
Electronic hazard
Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.
