Strengths as well as weaknesses of neodymium magnets.
Strengths
- Their power remains stable, and after approximately ten years it drops only by ~1% (theoretically),
- They retain their magnetic properties even under external field action,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Considering the possibility of free molding and adaptation to custom projects, neodymium magnets can be manufactured in a wide range of geometric configurations, which increases their versatility,
- Significant place in high-tech industry – they serve a role in mass storage devices, drive modules, advanced medical instruments, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. 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. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these products can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface free of scratches
- without any air gap between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Clearance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate lowers the holding force.
H&S for magnets
Thermal limits
Keep cool. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Do not give to children
Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Keep out of reach of children and animals.
Keep away from electronics
Remember: neodymium magnets produce a field that confuses precision electronics. Keep a safe distance from your phone, tablet, and GPS.
Warning for allergy sufferers
Studies show that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands or choose encased magnets.
Danger to pacemakers
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Protective goggles
Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets leads to them shattering into small pieces.
Safe distance
Data protection: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Crushing risk
Pinching hazard: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Do not drill into magnets
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Immense force
Exercise caution. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can move away.
