Here's an interesting observation...

I noticed that the taste of metal in my mouth was much stronger after I talked on my cell phone.

It's also interesting to consider that fillings with higher voltages on their surface emit much higher quantities of vapor (according to Huggins research). There is, of course, an intimate relationship between voltage and magnetic fields (one never exists without the other).

Also consider that magnetic fields induce voltage in conductive metals. So perhaps there is a positive feedback mechanism here.
