Strengths as well as weaknesses of rare earth magnets.
Benefits
- They retain magnetic properties for around 10 years – the loss is just ~1% (according to analyses),
- They have excellent resistance to weakening of magnetic properties due to external magnetic sources,
- In other words, due to the shiny surface of silver, the element is aesthetically pleasing,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of detailed machining as well as modifying to individual needs,
- Wide application in modern technologies – they serve a role in hard drives, motor assemblies, medical equipment, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases 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
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating threads in the magnet and complex forms - preferred is casing - magnet mounting.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these products are able to be problematic in diagnostics medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- using a plate made of low-carbon steel, acting as a circuit closing element
- whose thickness is min. 10 mm
- characterized by smoothness
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Gap (betwixt the magnet and the plate), as even a very small distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Direction of force – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the power to be escaped into the air.
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
- Plate texture – ground elements ensure maximum contact, which improves force. Uneven metal weaken the grip.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
This is not a toy
Neodymium magnets are not toys. Swallowing several magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and requires urgent medical intervention.
Data carriers
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Implant safety
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Heat sensitivity
Control the heat. Heating the magnet to high heat will permanently weaken its properties and strength.
Avoid contact if allergic
Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands and select coated magnets.
Powerful field
Use magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and do not underestimate their power.
Protective goggles
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Phone sensors
A strong magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.
Dust is flammable
Dust created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Hand protection
Danger of trauma: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
