Advantages and disadvantages of rare earth magnets.
Advantages
- Their power is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- They possess excellent resistance to magnetism drop due to external fields,
- By applying a smooth layer of gold, the element gains an modern look,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Due to the possibility of accurate molding and adaptation to specialized solutions, NdFeB magnets can be modeled in a broad palette of geometric configurations, which amplifies use scope,
- Fundamental importance in electronics industry – they are utilized in computer drives, electric motors, precision medical tools, as well as industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as 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 - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complicated forms - recommended is a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Maximum magnetic pulling force – what affects it?
- with the contact of a yoke made of low-carbon steel, ensuring maximum field concentration
- with a thickness minimum 10 mm
- with an ground contact surface
- with total lack of distance (no paint)
- during pulling in a direction perpendicular to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance (betwixt the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Safe handling of NdFeB magnets
Heat sensitivity
Keep cool. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Cards and drives
Avoid bringing magnets near a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Medical implants
People with a heart stimulator must keep an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Serious injuries
Danger of trauma: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Do not give to children
Adult use only. Tiny parts pose a choking risk, leading to serious injuries. Store out of reach of kids and pets.
Precision electronics
GPS units and smartphones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Allergic reactions
Some people have a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching might lead to a rash. We suggest use safety gloves.
Magnet fragility
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Dust is flammable
Machining of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Immense force
Use magnets consciously. Their huge power can shock even professionals. Be vigilant and respect their force.
