why is transformer buzzing

Many people attention that transformer is buzzing to a certain degree, but unknow why is transformer buzzing?

This is because the hum of the sound is due to the vibration of the core caused by alternating magnetic flux, generally speaking, the size of the sound is proportional to the additional voltage and current on the transformer. Under normal circumstances, the sound is continuous and uniform sound, such a situation is the normal operation of the transformer issued, the operation of the transformer will not affect, does not represent the transformer itself has a problem.

Till here, do you understand why transformer is buzzing?
