Pros and cons of rare earth magnets.
Pros
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They retain their magnetic properties even under external field action,
- Thanks to the shimmering finish, the coating of Ni-Cu-Ni, gold, or silver gives an modern appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the option of precise forming and adaptation to specialized projects, neodymium magnets can be produced in a variety of forms and dimensions, which increases their versatility,
- Versatile presence in modern industrial fields – they serve a role in magnetic memories, drive modules, medical equipment, also technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating nuts in the magnet and complex forms - preferred is casing - magnet mounting.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these products can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a plate made of high-permeability steel, acting as a ideal flux conductor
- with a cross-section of at least 10 mm
- with a plane free of scratches
- without any air gap between the magnet and steel
- under axial application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be escaped into the air.
- Material composition – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Finger safety
Watch your fingers. Two large magnets will join immediately with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Precision electronics
Remember: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
Heat warning
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Fire risk
Machining of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Beware of splinters
Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets will cause them breaking into shards.
Powerful field
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Swallowing risk
Strictly store magnets away from children. Risk of swallowing is high, and the effects of magnets connecting inside the body are very dangerous.
Danger to pacemakers
Patients with a ICD should maintain an safe separation from magnets. The magnetism can interfere with the functioning of the implant.
Avoid contact if allergic
It is widely known that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, refrain from direct skin contact or choose coated magnets.
Electronic devices
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
