Pros and cons of rare earth magnets.
Strengths
- They do not lose strength, even after around ten years – the decrease in strength is only ~1% (based on measurements),
- They feature excellent resistance to magnetic field loss due to opposing magnetic fields,
- In other words, due to the shiny layer of silver, the element looks attractive,
- Magnetic induction on the working layer of the magnet is extremely intense,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of custom creating and adjusting to atypical applications,
- Huge importance in modern technologies – they are used in computer drives, electric motors, medical devices, as well as complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets decrease their strength 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 rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using casing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a plate made of high-permeability steel, serving as a ideal flux conductor
- whose transverse dimension reaches at least 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at room temperature
What influences lifting capacity in practice
- Gap (betwixt the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Safe handling of neodymium magnets
Immense force
Be careful. Rare earth magnets act from a long distance and connect with huge force, often faster than you can react.
ICD Warning
People with a ICD should maintain an large gap from magnets. The magnetic field can interfere with the functioning of the implant.
Protective goggles
Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
Magnetic interference
GPS units and mobile phones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Machining danger
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Allergy Warning
Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and opt for versions in plastic housing.
Heat warning
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.
Choking Hazard
Always store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are fatal.
Finger safety
Risk of injury: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Electronic devices
Avoid bringing magnets near a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
