Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
- A magnet with a shiny nickel surface has better aesthetics,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to freedom in constructing and the ability to modify to client solutions,
- Key role in electronics industry – they find application in HDD drives, electric drive systems, precision medical tools, as well as other advanced devices.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose their force 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in realizing threads and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- using a sheet made of low-carbon steel, acting as a circuit closing element
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane perfectly flat
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (rust, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be wasted to the other side.
- Plate material – mild steel attracts best. Higher carbon content decrease magnetic permeability and holding force.
- Smoothness – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Maximum temperature
Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Avoid contact if allergic
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease handling magnets and wear gloves.
This is not a toy
Absolutely store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.
Serious injuries
Watch your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Dust explosion hazard
Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Conscious usage
Be careful. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can react.
Risk of cracking
Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Protect data
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.
GPS and phone interference
A powerful magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Maintain magnets near a smartphone to avoid damaging the sensors.
Danger to pacemakers
Individuals with a pacemaker should keep an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.
