Pros and cons of neodymium magnets.
Pros
- They retain full power for almost ten years – the drop is just ~1% (in theory),
- They do not lose their magnetic properties even under strong external field,
- Thanks to the shimmering finish, the plating of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- 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...
- Possibility of custom machining and modifying to complex conditions,
- Fundamental importance in advanced technology sectors – they are used in HDD drives, brushless drives, advanced medical instruments, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in small systems
Weaknesses
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited possibility of making nuts in the magnet and complex shapes - recommended is casing - magnetic holder.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small elements of these devices are able to complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- using a base made of low-carbon steel, acting as a magnetic yoke
- whose thickness equals approx. 10 mm
- with an polished contact surface
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at temperature room level
Magnet lifting force in use – key factors
- Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick steel does not close the flux, causing part of the flux to be lost to the other side.
- Metal type – different alloys reacts the same. High carbon content weaken the attraction effect.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Combustion hazard
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Handling rules
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Medical implants
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Choking Hazard
These products are not intended for children. Eating several magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
Metal Allergy
Some people suffer from a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Prolonged contact may cause a rash. It is best to use protective gloves.
Serious injuries
Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!
Phone sensors
A powerful magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Do not bring magnets close to a device to prevent damaging the sensors.
Material brittleness
Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Operating temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Magnetic media
Do not bring magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
