The gauss of a magnet, also known as the magnet surface magnetism, is a kind of magnetic data measured by a gaussmeter, and the gauss value of a magnet can reflect the high and low magnetic properties of a magnet side by side, and some netizens have asked to which type of magnet the 800 gauss magnet belongs to?
An 800 Gauss magnet is highly likely to be an sintered anisotropic ceramic ferrite
Sintered ferrite magnets are a cheaper and corrosion resistant hard magnetic material. Its magnetic field strength is much weaker than that of NdFeB, and the magnetic strength of each homogeneous grade is generally lower than 800 gauss, and 500-600 gauss is more common. The anisotropic grade is generally around 800-1100 gauss, mostly used in Hall sensors, household appliances, micro-motors and other fields.
The image below shows an 815 gauss rectangular perforated ferrite magnet.
Second, 800 gauss could also be a rare earth neodymium magnets.
You may be curious. Aren't neodymium magnets usually higher than 2000 gauss? How can it be 800 gauss? This you do not know, the gauss strength of the magnet is related to the size, in general, the larger the size, the thinner it is, the lower its surface magnetic data will be, especially the center surface magnetic.
It may also be flexible rubber NdFeB.
We may have more contact with the flexible rubber ferrite, flexible neodymium iron boron and flexible ferrite lies in the difference between the magnetic powder, higher than the ferrite magnetic energy product, to reach 800 gauss is easier.
So, relying solely on an 800 Gauss magnet cannot determine the specific material of the magnet. It could be ferrite, neodymium iron boron, samarium cobalt, or other materials, but it is more likely to be sintered ceramic ferrite. If there are samples, they can be judged by appearance.
