Strengths and weaknesses of neodymium magnets.
Pros
- They do not lose power, even during around 10 years – the decrease in lifting capacity is only ~1% (theoretically),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a shiny nickel surface has an effective appearance,
- Magnets have huge magnetic induction on the outer layer,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- In view of the possibility of precise shaping and customization to specialized projects, magnetic components can be produced in a wide range of shapes and sizes, which expands the range of possible applications,
- Wide application in high-tech industry – they are used in mass storage devices, electromotive mechanisms, diagnostic systems, also multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- 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.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complicated forms in magnets, we recommend using casing - magnetic mount.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices can be problematic in diagnostics medical in case of swallowing.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum magnetic pulling force – what affects it?
- on a block made of structural steel, effectively closing the magnetic field
- with a thickness of at least 10 mm
- characterized by even structure
- without any insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Key elements affecting lifting force
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy steels decrease magnetic properties and holding force.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Warnings
Powerful field
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Magnets are brittle
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Metal Allergy
Studies show that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands or select encased magnets.
Electronic devices
Data protection: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Magnetic interference
Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Danger to pacemakers
People with a heart stimulator have to keep an safe separation from magnets. The magnetic field can disrupt the operation of the life-saving device.
Combustion hazard
Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Finger safety
Big blocks can break fingers instantly. Never place your hand between two attracting surfaces.
Heat sensitivity
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Product not for children
Adult use only. Small elements can be swallowed, causing serious injuries. Store away from children and animals.
