my Magsafe is giving out small soft "bzzz" sounds when charging

many people might not notice this, but when you try to charge your MBP, i put my ears close to the Magsafe, you can hear like a rattle snake bzzzing but it's rather small

is that something wrong? or is it just the mechanical sounds when its charging?

thanks
 
If it's not getting hot, I wouldn't worry about it. There could be a loose winding or it's an oscillator, depending on what method they are using to drop the voltage from the mains to the charging voltage.
