Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They do not lose power, even during nearly 10 years – the drop in lifting capacity is only ~1% (theoretically),
- They feature excellent resistance to magnetism drop as a result of opposing magnetic fields,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets achieve maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Due to the potential of flexible forming and adaptation to custom requirements, NdFeB magnets can be created in a wide range of geometric configurations, which makes them more universal,
- Huge importance in future technologies – they find application in data components, electric drive systems, advanced medical instruments, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 very resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in realizing nuts and complex shapes in magnets, we recommend using casing - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Additionally, small components 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
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- using a plate made of low-carbon steel, acting as a circuit closing element
- possessing a thickness of min. 10 mm to avoid saturation
- with an ground contact surface
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction vertical to the plane
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy admixtures decrease magnetic permeability and holding force.
- Surface condition – ground elements ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with neodymium magnets
Skin irritation risks
It is widely known that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact or select coated magnets.
Threat to navigation
A powerful magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to prevent damaging the sensors.
Risk of cracking
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Protect data
Do not bring magnets close to a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Warning for heart patients
People with a ICD should keep an large gap from magnets. The magnetic field can interfere with the functioning of the implant.
Fire risk
Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Choking Hazard
These products are not intended for children. Swallowing several magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and necessitates urgent medical intervention.
Handling rules
Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their force.
Serious injuries
Danger of trauma: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Heat warning
Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
