Pros as well as cons of rare earth magnets.
Pros
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
- Magnets effectively protect themselves against loss of magnetization caused by ambient magnetic noise,
- By covering with a reflective layer of gold, the element has an aesthetic look,
- They show high magnetic induction at the operating surface, making them more effective,
- 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...
- Due to the option of flexible forming and adaptation to unique requirements, NdFeB magnets can be modeled in a wide range of forms and dimensions, which expands the range of possible applications,
- Significant place in advanced technology sectors – they are utilized in mass storage devices, electric drive systems, diagnostic systems, and modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- We suggest casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these magnets are able to complicate diagnosis medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a base made of low-carbon steel, functioning as a circuit closing element
- whose thickness reaches at least 10 mm
- characterized by lack of roughness
- without any clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Threat to navigation
An intense magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Keep magnets near a smartphone to avoid breaking the sensors.
Caution required
Be careful. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can react.
Safe distance
Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Thermal limits
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Magnets are brittle
Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Do not drill into magnets
Dust produced during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
Swallowing risk
Only for adults. Tiny parts pose a choking risk, causing severe trauma. Store away from children and animals.
Warning for allergy sufferers
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Finger safety
Pinching hazard: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Implant safety
Patients with a pacemaker have to keep an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
