Pros and cons of neodymium magnets.
Benefits
- Their magnetic field is durable, and after approximately 10 years it drops only by ~1% (according to research),
- They feature excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets are distinguished by impressive magnetic induction on the outer side,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in designing and the capacity to customize to complex applications,
- Huge importance in electronics industry – they are utilized in hard drives, drive modules, precision medical tools, also multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complex forms in magnets, we recommend using cover - magnetic mount.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these products can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a block made of mild steel, effectively closing the magnetic field
- whose thickness equals approx. 10 mm
- with an ideally smooth contact surface
- with zero gap (no impurities)
- under perpendicular force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Distance – the presence of foreign body (rust, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
- Surface finish – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Life threat
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Do not underestimate power
Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can react.
Fragile material
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Serious injuries
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Data carriers
Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
No play value
Strictly keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are fatal.
GPS and phone interference
A powerful magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a smartphone to avoid damaging the sensors.
Permanent damage
Control the heat. Heating the magnet to high heat will destroy its properties and pulling force.
Nickel allergy
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact or choose encased magnets.
Fire risk
Powder produced during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
