Advantages and disadvantages of rare earth magnets.
Strengths
- They do not lose strength, even over approximately 10 years – the decrease in strength is only ~1% (theoretically),
- They feature excellent resistance to magnetism drop as a result of external magnetic sources,
- A magnet with a metallic silver surface has an effective appearance,
- They feature high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Due to the option of free molding and customization to custom needs, NdFeB magnets can be created in a variety of forms and dimensions, which makes them more universal,
- Fundamental importance in electronics industry – they are utilized in HDD drives, electric drive systems, medical equipment, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these products are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- using a plate made of high-permeability steel, serving as a magnetic yoke
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an polished contact surface
- with zero gap (no coatings)
- during pulling in a direction perpendicular to the plane
- at ambient temperature room level
Key elements affecting lifting force
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin sheet does not accept the full field, causing part of the flux to be wasted to the other side.
- Material composition – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.
Precautions when working with neodymium magnets
Material brittleness
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Skin irritation risks
A percentage of the population have a contact allergy to Ni, which is the standard coating for neodymium magnets. Extended handling can result in skin redness. We suggest use safety gloves.
Heat warning
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.
Life threat
Individuals with a pacemaker should maintain an absolute distance from magnets. The magnetism can stop the operation of the implant.
Bone fractures
Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
GPS Danger
An intense magnetic field negatively affects the operation of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent damaging the sensors.
Dust explosion hazard
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Choking Hazard
Absolutely keep magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.
Electronic hazard
Do not bring magnets close to a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.
Conscious usage
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
