Do all toroidal transformers hum?

Help Gurus,

When I put my ear (about 2 inches from the top)to my integrated amplifier, I can hear a faint hum from both the transformers. Can't hear anything when I move my ear away from the amp. Is this normal?

Gbart was kind enough to make me a simple DC blocker (with high quality Caps and resistors). I received it last night, I plugged the amp into it and VOILA NO MORE HUM. Not even a hint of it. I pressed my ear against the amp. to hear the faintest hum, but nothing, absolute SILENCE. You won't believe how much the DC blocker from Gbart costed... $72. Yes it's just Seventy Two dollats. THANKS GBART
