I take ExSp33db1rd's point, but the phone was in between the 'dail' and the radio stack.
Also those magnets were huge, and certainly can do some damage, i'm an IT geek by trade and have seen Harddrives sitting on large speaker stacks wiped (certainly corupted) by the magnets they contain.
As for the Mag Compass i was told don't even leave car keys near them!!!
