It is controversial whether neodymium iron boron magnets have magnetism as soon as they are produced. Some people think that magnets have magnetism as soon as they are made, while others think that they have no magnetism. Today, Xiao Fu from Courage Magnet Factory came to popularize this knowledge.
Does NdFeB neodymium magnet have magnetism when it is produced?
No, The newly cut magnet is not magnetized, so you need to use a magnetizing device(Magnetizer) to magnetize the magnet.
In which link is NdFeB magnet magnetized?
If the customer requires magnetizing for delivery, the last process is to put the qualified neodymium magnet into the magnetizing coil and turn it into a magnetic field through current, so the magnetizing is completed after the electroplating.
Points needing special attention:
The most important magnetization direction of the magnet is the magnetization direction. Once the magnetization direction is wrong, you can only take it for demagnetization, which is time-consuming, laborious and expensive.
The above is about whether introduce the magnet is magnetic after production . Our company mainly sells various micro precision magnets, multipole ring magnets, motor arc magnets, etc. Welcome to inquire about the price.
Guess you also pay attention to the following magnetization related issues;
Can the axially magnetized magnet be demagnetized for radial magnetization?
Axial 2 pole magnetization schematic sharing
Is the magnet magnetization waveform sine wave or square wave good?
