Advantages and disadvantages of neodymium magnets.
Advantages
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They do not lose their magnetic properties even under strong external field,
- In other words, due to the shiny surface of silver, the element gains a professional look,
- Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Considering the option of flexible molding and customization to custom needs, magnetic components can be created in a broad palette of geometric configurations, which increases their versatility,
- Fundamental importance in modern technologies – they find application in mass storage devices, motor assemblies, precision medical tools, as well as modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 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 secure oxidation as well as corrosion.
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using cover - magnetic mechanism.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these devices are able to disrupt the diagnostic process medical after entering the body.
- Due to neodymium price, their price exceeds standard values,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a base made of low-carbon steel, serving as a circuit closing element
- with a cross-section no less than 10 mm
- with a plane cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Clearance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet and the plate lowers the holding force.
Precautions when working with NdFeB magnets
This is not a toy
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from kids and pets.
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop working with magnets and use protective gear.
Magnetic media
Do not bring magnets near a wallet, laptop, or screen. The magnetic field can destroy these devices and wipe information from cards.
Crushing risk
Pinching hazard: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
Fragile material
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Handling rules
Use magnets with awareness. Their huge power can shock even professionals. Stay alert and do not underestimate their force.
Permanent damage
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Health Danger
Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Compass and GPS
A strong magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Do not bring magnets close to a device to prevent damaging the sensors.
Dust is flammable
Dust generated during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
