Pros and cons of rare earth magnets.
Strengths
- They do not lose power, even during approximately ten years – the decrease in power is only ~1% (theoretically),
- Magnets effectively protect themselves against demagnetization caused by external fields,
- A magnet with a shiny gold surface has an effective appearance,
- They feature high magnetic induction at the operating surface, making them more effective,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in shaping and the capacity to modify to client solutions,
- Key role in high-tech industry – they find application in magnetic memories, electric motors, precision medical tools, as well as technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in special holders. 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 strength. Often, when the temperature exceeds 80°C, their power 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
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in creating threads and complicated forms in magnets, we propose using casing - magnetic mechanism.
- Health risk to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Maximum holding power of the magnet – what affects it?
- with the application of a yoke made of special test steel, guaranteeing maximum field concentration
- with a thickness of at least 10 mm
- with a plane cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Distance (between the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Implant safety
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Eye protection
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them breaking into small pieces.
Respect the power
Use magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and do not underestimate their force.
Phone sensors
Navigation devices and mobile phones are highly susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Machining danger
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Serious injuries
Risk of injury: The pulling power is so great that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Cards and drives
Avoid bringing magnets close to a purse, computer, or TV. The magnetism can destroy these devices and erase data from cards.
No play value
Adult use only. Small elements pose a choking risk, causing severe trauma. Store out of reach of kids and pets.
Demagnetization risk
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.
Allergic reactions
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness appears, cease working with magnets and use protective gear.
