Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They retain full power for nearly ten years – the drop is just ~1% (according to analyses),
- They have excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
- By covering with a decorative layer of gold, the element acquires an aesthetic look,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to versatility in constructing and the ability to modify to specific needs,
- Universal use in innovative solutions – they serve a role in computer drives, electromotive mechanisms, medical devices, and industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Limitations
- At 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.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in creating threads and complex forms in magnets, we recommend using cover - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Additionally, small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- using a sheet made of mild steel, acting as a magnetic yoke
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- without any insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Space between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, 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 maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Steel type – low-carbon steel attracts best. Alloy admixtures decrease magnetic permeability and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Risk of cracking
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.
Respect the power
Exercise caution. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can react.
Keep away from computers
Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Compass and GPS
An intense magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.
Dust is flammable
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Serious injuries
Protect your hands. Two large magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!
Permanent damage
Keep cool. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Allergic reactions
Studies show that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or select coated magnets.
No play value
Only for adults. Tiny parts pose a choking risk, leading to serious injuries. Store away from children and animals.
ICD Warning
Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
