Pros and cons of rare earth magnets.
Benefits
- They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- Magnets very well resist against demagnetization caused by foreign field sources,
- By covering with a smooth layer of gold, the element gains an modern look,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
- Possibility of precise creating and adjusting to individual applications,
- Versatile presence in electronics industry – they are commonly used in data components, electric motors, medical devices, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We suggest a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to complicate diagnosis 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
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the contact of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- with zero gap (without paint)
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Key elements affecting lifting force
- Clearance – existence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material composition – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Health Danger
For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.
Heat sensitivity
Monitor thermal conditions. Heating the magnet to high heat will ruin its magnetic structure and pulling force.
Crushing force
Protect your hands. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!
Fire risk
Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
Adults only
Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are life-threatening.
Keep away from computers
Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Avoid contact if allergic
A percentage of the population suffer from a contact allergy to nickel, which is the common plating for neodymium magnets. Prolonged contact may cause dermatitis. We recommend wear safety gloves.
Threat to navigation
A powerful magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Do not bring magnets close to a device to prevent breaking the sensors.
Eye protection
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Powerful field
Be careful. Rare earth magnets act from a distance and connect with massive power, often quicker than you can move away.
