Pros and cons of rare earth magnets.
Benefits
- Their magnetic field is durable, and after approximately 10 years it drops only by ~1% (according to research),
- They are resistant to demagnetization induced by external magnetic fields,
- The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets create maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of individual forming and modifying to concrete conditions,
- Universal use in advanced technology sectors – they are utilized in mass storage devices, electric motors, medical equipment, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products can complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a sheet made of mild steel, serving as a ideal flux conductor
- with a cross-section of at least 10 mm
- with a plane free of scratches
- without the slightest clearance between the magnet and steel
- under vertical force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick steel does not close the flux, causing part of the power to be lost to the other side.
- Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Warnings
Do not underestimate power
Handle magnets with awareness. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their power.
Phone sensors
Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Fire warning
Powder created during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Eye protection
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Protect data
Avoid bringing magnets near a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Heat sensitivity
Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.
Nickel coating and allergies
Studies show that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands and opt for coated magnets.
Crushing force
Risk of injury: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Pacemakers
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
No play value
Absolutely store magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.
