Pros as well as cons of neodymium magnets.
Pros
- They retain attractive force for almost 10 years – the loss is just ~1% (in theory),
- Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external interference,
- In other words, due to the shiny finish of nickel, the element gains visual value,
- Magnets are distinguished by excellent magnetic induction on the outer side,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Due to the possibility of precise molding and customization to specialized solutions, neodymium magnets can be produced in a broad palette of forms and dimensions, which increases their versatility,
- Fundamental importance in modern technologies – they are utilized in magnetic memories, drive modules, advanced medical instruments, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and 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, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these devices can be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price exceeds standard values,
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- using a base made of high-permeability steel, serving as a magnetic yoke
- whose transverse dimension reaches at least 10 mm
- with an ideally smooth touching surface
- without any air gap between the magnet and steel
- under axial force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap (between the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Angle of force application – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick sheet does not close the flux, causing part of the power to be escaped into the air.
- Chemical composition of the base – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
Magnet fragility
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Compass and GPS
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Physical harm
Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Dust explosion hazard
Dust generated during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Thermal limits
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and strength.
Choking Hazard
Product intended for adults. Small elements can be swallowed, causing intestinal necrosis. Store away from kids and pets.
Electronic hazard
Intense magnetic fields can destroy records on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
Do not underestimate power
Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can react.
Nickel allergy
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness appears, cease working with magnets and use protective gear.
Pacemakers
Warning for patients: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.
