Strengths and weaknesses of rare earth magnets.
Advantages
- Their power is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
- They feature excellent resistance to magnetic field loss due to external magnetic sources,
- A magnet with a metallic silver surface has an effective appearance,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which increases force concentration,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Thanks to versatility in designing and the capacity to adapt to unusual requirements,
- Huge importance in innovative solutions – they are utilized in mass storage devices, electric motors, diagnostic systems, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small components of these devices can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- using a plate made of high-permeability steel, acting as a magnetic yoke
- with a cross-section of at least 10 mm
- with an ground contact surface
- with total lack of distance (without coatings)
- under perpendicular force direction (90-degree angle)
- at temperature room level
Lifting capacity in real conditions – factors
- Clearance – the presence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Risk of cracking
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Bone fractures
Risk of injury: The attraction force is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Do not underestimate power
Exercise caution. Neodymium magnets act from a distance and snap with massive power, often faster than you can move away.
Magnetic media
Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Dust is flammable
Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.
Do not overheat magnets
Control the heat. Exposing the magnet to high heat will ruin its magnetic structure and strength.
GPS Danger
Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Choking Hazard
Strictly store magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are fatal.
Medical implants
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
