Strengths and weaknesses of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They maintain their magnetic properties even under close interference source,
- In other words, due to the glossy surface of gold, the element gains a professional look,
- Magnets possess huge magnetic induction on the outer layer,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Considering the ability of flexible molding and customization to custom projects, magnetic components can be produced in a wide range of shapes and sizes, which increases their versatility,
- Wide application in modern industrial fields – they are used in magnetic memories, drive modules, diagnostic systems, also modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer 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
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in producing threads and complex forms in magnets, we recommend using cover - magnetic holder.
- Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these products can disrupt the diagnostic process medical after entering the body.
- Due to complex production process, their price is relatively high,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the contact of a sheet made of special test steel, ensuring full magnetic saturation
- with a cross-section of at least 10 mm
- with a plane perfectly flat
- under conditions of no distance (surface-to-surface)
- under vertical application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Clearance – existence of foreign body (paint, tape, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick steel does not close the flux, causing part of the flux to be lost to the other side.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy steels lower magnetic permeability and holding force.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Temperature influence – hot environment 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 the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Protect data
Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Magnet fragility
Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Avoid contact if allergic
Certain individuals have a sensitization to nickel, which is the common plating for NdFeB magnets. Prolonged contact might lead to skin redness. We strongly advise use protective gloves.
Mechanical processing
Powder created during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Phone sensors
A strong magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Keep magnets close to a device to prevent breaking the sensors.
Danger to pacemakers
Individuals with a heart stimulator should keep an absolute distance from magnets. The magnetism can disrupt the operation of the implant.
Heat warning
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Physical harm
Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
This is not a toy
These products are not suitable for play. Swallowing several magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.
Powerful field
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
