Advantages as well as disadvantages of neodymium magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- A magnet with a smooth gold surface has better aesthetics,
- Magnets exhibit impressive magnetic induction on the outer layer,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Due to the option of flexible shaping and adaptation to custom solutions, magnetic components can be manufactured in a wide range of forms and dimensions, which amplifies use scope,
- Significant place in innovative solutions – they serve a role in HDD drives, electric motors, medical devices, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in small systems
Cons
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We suggest casing - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small elements of these devices are able to complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- using a plate made of high-permeability steel, serving as a ideal flux conductor
- whose thickness equals approx. 10 mm
- characterized by smoothness
- with direct contact (no impurities)
- during pulling in a direction perpendicular to the plane
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Distance (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and holding force.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity was assessed using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.
Safe handling of neodymium magnets
Danger to the youngest
Always keep magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are life-threatening.
Hand protection
Big blocks can break fingers instantly. Under no circumstances put your hand between two strong magnets.
Operating temperature
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Fire risk
Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Danger to pacemakers
Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or request help to work with the magnets.
Safe distance
Very strong magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Handling guide
Handle with care. Rare earth magnets act from a distance and connect with massive power, often faster than you can react.
Magnets are brittle
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
GPS Danger
A powerful magnetic field disrupts the functioning of compasses in phones and navigation systems. Keep magnets near a smartphone to avoid breaking the sensors.
Allergic reactions
Medical facts indicate that nickel (the usual finish) is a common allergen. If your skin reacts to metals, prevent direct skin contact or select versions in plastic housing.
