Strengths as well as weaknesses of neodymium magnets.
Benefits
- They retain attractive force for around 10 years – the loss is just ~1% (based on simulations),
- Magnets very well defend themselves against demagnetization caused by foreign field sources,
- In other words, due to the shiny layer of gold, the element looks attractive,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in shaping and the capacity to customize to unusual requirements,
- Significant place in electronics industry – they find application in computer drives, electric drive systems, medical equipment, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- using a plate made of mild steel, acting as a ideal flux conductor
- with a thickness of at least 10 mm
- with an ideally smooth contact surface
- with direct contact (no paint)
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
What influences lifting capacity in practice
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick plate does not close the flux, causing part of the flux to be lost to the other side.
- Material type – the best choice is pure iron steel. Stainless steels may attract less.
- Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Protective goggles
Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Do not underestimate power
Use magnets with awareness. Their huge power can surprise even experienced users. Plan your moves and respect their force.
Warning for heart patients
For implant holders: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Adults only
Product intended for adults. Small elements can be swallowed, causing serious injuries. Keep out of reach of children and animals.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop working with magnets and use protective gear.
Fire risk
Machining of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Data carriers
Powerful magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Thermal limits
Watch the temperature. Exposing the magnet to high heat will ruin its properties and pulling force.
Bone fractures
Large magnets can crush fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
GPS and phone interference
A strong magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets near a device to prevent breaking the sensors.
