iPod Erm, stupid question

I've noticed that every time I go through the security gate at the library of the hospital I work in, I hear a faint, high-pitched whine. I put two and two together quickly and realized it was the iPod that was responsible. I don't know how those gates work except I sort of figure that if the security device is magnetic, the gates are checking for a certain...polarity? Or something. I really don't know magnets. ;) So assuming this is the case, I figure it must be the battery that causes that noise.

I don't imagine there's any harm in this, really, but I just wanted to make sure--it's not going to do damage, is it?

So...should I turn it off? Would that matter? I mean, I'm over there for 4 hours for a shift and bring it with me for the walk there, the walk back, and the time I'm there. I can't imagine it's too damaging because...I mean, people with pacemakers have to shop, right? And how do you get a purchased computer through the security gates without killing it?

Don't worry, security gates won't mess with your pod.
You should be fine.

Security gates respond to the frequency emitted by the security device in the object, not by magnetic means.
