Advantages as well as disadvantages of rare earth magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Magnets very well defend themselves against loss of magnetization caused by ambient magnetic noise,
- By using a lustrous layer of gold, the element acquires an nice look,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to flexibility in forming and the ability to adapt to unusual requirements,
- Significant place in high-tech industry – they are commonly used in mass storage devices, electric drive systems, precision medical tools, also multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Limitations
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited ability of making threads in the magnet and complex forms - recommended is a housing - magnetic holder.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a sheet made of low-carbon steel, serving as a magnetic yoke
- whose thickness reaches at least 10 mm
- with an ground touching surface
- without the slightest insulating layer between the magnet and steel
- during detachment in a direction vertical to the plane
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Distance (between the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and holding force.
- Smoothness – full contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Warnings
Implant safety
For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Heat warning
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Allergic reactions
Some people suffer from a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching may cause dermatitis. It is best to wear safety gloves.
Hand protection
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Product not for children
Adult use only. Small elements pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.
Beware of splinters
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets leads to them cracking into shards.
Data carriers
Avoid bringing magnets close to a purse, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Flammability
Dust generated during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Handling guide
Handle magnets consciously. Their huge power can shock even experienced users. Be vigilant and respect their power.
Precision electronics
GPS units and mobile phones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
