Pros as well as cons of rare earth magnets.
Advantages
- They have unchanged lifting capacity, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under external field action,
- Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold, or silver gives an visually attractive appearance,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in constructing and the capacity to modify to unusual requirements,
- Huge importance in advanced technology sectors – they are used in computer drives, electric motors, medical devices, and multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can lose 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 suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complex forms in magnets, we propose using casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these devices can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- using a plate made of mild steel, serving as a magnetic yoke
- with a cross-section of at least 10 mm
- with a plane free of scratches
- without any insulating layer between the magnet and steel
- during detachment in a direction vertical to the plane
- at standard ambient temperature
Impact of factors on magnetic holding capacity in practice
- Gap (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, rust or debris).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Smoothness – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.
Warnings
Heat warning
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and strength.
Machining danger
Dust generated during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Product not for children
Absolutely store magnets away from children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are very dangerous.
Metal Allergy
A percentage of the population have a sensitization to Ni, which is the typical protective layer for neodymium magnets. Extended handling might lead to an allergic reaction. We strongly advise use safety gloves.
Impact on smartphones
Be aware: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.
Eye protection
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Magnetic media
Very strong magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.
Implant safety
Patients with a ICD must keep an large gap from magnets. The magnetic field can stop the functioning of the implant.
Serious injuries
Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Handling rules
Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their power.
