How many gauss is 20mm thick rare earth neodymium magnet?

The magnetic field strength of rare earth neodymium magnets not only depends on its thickness, but also affected by other factors, such as the performance grade, size and shape of the magnet, generally speaking, the magnetic field strength can be expressed in Gauss or Tesla, here are some 2cm thick neodymium round/block/ring magnets surface magnetic strength listed for you for reference.
