Advantages and disadvantages of rare earth magnets.
Strengths
- Their magnetic field remains stable, and after approximately ten years it decreases only by ~1% (theoretically),
- Neodymium magnets are distinguished by exceptionally resistant to magnetic field loss caused by external magnetic fields,
- In other words, due to the aesthetic layer of silver, the element gains a professional look,
- Magnets are characterized by very high magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in designing and the capacity to adapt to complex applications,
- Huge importance in future technologies – they are used in computer drives, electric motors, medical equipment, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in small systems
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer 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 start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of making nuts in the magnet and complex shapes - preferred is casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a sheet made of high-permeability steel, acting as a magnetic yoke
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- with total lack of distance (without impurities)
- during pulling in a direction perpendicular to the mounting surface
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Air gap (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
- Base massiveness – too thin steel does not close the flux, causing part of the power to be wasted to the other side.
- Steel grade – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Temperature – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Magnets are brittle
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Handling rules
Handle magnets consciously. Their huge power can surprise even experienced users. Be vigilant and respect their power.
Medical implants
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Electronic hazard
Avoid bringing magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Product not for children
These products are not suitable for play. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and necessitates immediate surgery.
Mechanical processing
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Threat to navigation
Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Avoid contact if allergic
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, prevent touching magnets with bare hands and select coated magnets.
Bone fractures
Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Demagnetization risk
Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and pulling force.
