Dear readers!
I wanted to arrange a little demonstration for my relatives with my cellphone inside a Faraday cage. Of course I expected no EM waves to be present inside the cage, which means that my cellphone wouldn't ring when being called. Well, we repeated the experiment several times, placing the box at different points and (a few times) it did.
As a "cage" I used a closed box made of some kind of thin metall. Unfortunately I don't know what it is, but it attracts a magnet.
My question is why it didn't work. Do you think that the conductivity of the material in question wasn't high enough, thus causing the charges not to arrange themselves quickly enough in positions suitable for neutralizing the external field? Could there be an other reason? Do you know any metalls not suitable for constructing a good Faraday cage?
Thanks in advance for any help,
Angelos
