Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- Their strength is durable, and after around ten years it decreases only by ~1% (according to research),
- They feature excellent resistance to magnetic field loss due to opposing magnetic fields,
- In other words, due to the reflective surface of nickel, the element gains a professional look,
- Magnetic induction on the top side of the magnet is exceptional,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in shaping and the capacity to customize to client solutions,
- Versatile presence in high-tech industry – they are utilized in data components, electric motors, diagnostic systems, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their 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 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 and corrosion.
- Due to limitations in realizing threads and complex forms in magnets, we propose using casing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these devices are able to disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Highest magnetic holding force – what affects it?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- whose transverse dimension is min. 10 mm
- characterized by even structure
- with total lack of distance (no coatings)
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
What influences lifting capacity in practice
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin sheet causes magnetic saturation, causing part of the power to be wasted into the air.
- Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface finish – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Powerful field
Use magnets with awareness. Their huge power can shock even experienced users. Be vigilant and do not underestimate their power.
Heat warning
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Crushing force
Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Threat to electronics
Do not bring magnets close to a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Fire warning
Dust created during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
No play value
Neodymium magnets are not toys. Swallowing multiple magnets can lead to them attracting across intestines, which constitutes a critical condition and requires immediate surgery.
Life threat
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Compass and GPS
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Protective goggles
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Nickel allergy
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from direct skin contact and opt for encased magnets.
