Pros as well as cons of rare earth magnets.
Pros
- Their magnetic field is durable, and after around 10 years it decreases only by ~1% (theoretically),
- They show high resistance to demagnetization induced by external field influence,
- Thanks to the glossy finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an modern appearance,
- Magnets possess impressive magnetic induction on the active area,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of individual creating as well as modifying to atypical needs,
- Fundamental importance in high-tech industry – they are used in mass storage devices, motor assemblies, advanced medical instruments, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems
Limitations
- At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these products are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- with zero gap (without impurities)
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Air gap (between the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
- Angle of force application – maximum parameter is reached 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).
- Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the power to be escaped into the air.
- Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Avoid contact if allergic
Some people experience a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact may cause a rash. It is best to wear safety gloves.
Phone sensors
GPS units and smartphones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Fire warning
Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Physical harm
Protect your hands. Two large magnets will join immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Handling rules
Be careful. Neodymium magnets act from a long distance and connect with massive power, often faster than you can react.
Material brittleness
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Pacemakers
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Adults only
Product intended for adults. Small elements pose a choking risk, causing intestinal necrosis. Store away from kids and pets.
Threat to electronics
Avoid bringing magnets close to a wallet, computer, or TV. The magnetism can destroy these devices and erase data from cards.
Thermal limits
Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
