Pros as well as cons of rare earth magnets.
Strengths
- They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
- They do not lose their magnetic properties even under close interference source,
- A magnet with a shiny silver surface has an effective appearance,
- Magnetic induction on the working layer of the magnet remains strong,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Possibility of individual machining as well as modifying to specific requirements,
- Universal use in innovative solutions – they serve a role in hard drives, motor assemblies, medical equipment, and technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At very 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.
- Neodymium magnets decrease 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 stability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of making threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a thickness of at least 10 mm to avoid saturation
- with a surface perfectly flat
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Key elements affecting lifting force
- Clearance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Surface finish – ideal contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity was determined by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Warnings
Serious injuries
Watch your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Keep away from children
Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Store away from kids and pets.
Compass and GPS
Be aware: rare earth magnets produce a field that interferes with precision electronics. Keep a safe distance from your phone, tablet, and GPS.
Nickel allergy
It is widely known that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, avoid direct skin contact and select encased magnets.
ICD Warning
Individuals with a ICD must keep an safe separation from magnets. The magnetism can disrupt the operation of the implant.
Magnet fragility
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Heat sensitivity
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.
Threat to electronics
Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Handling guide
Exercise caution. Rare earth magnets attract from a long distance and connect with huge force, often faster than you can react.
Combustion hazard
Fire warning: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
