Not true in all cases. If the wire is long enough, the intensity is large enough and the voltage created exceeds a certain amount it will create its own circuit. That is what lightning is.

However, if the wire is small enough it will be fine. The EMP generated is relative to the length of the wire.

I remember in college my teacher saying that an induced charge like an EMP will disipate where possible. So a lightbulb will transfer the electrical energy as long as it's grounded, through light. Same as a flurescent tube light will. Same with speakers, the lecturer said they disipated the energy at the same rate they are charged, i.e. the tone from the speaker is the same frequency of the charging. The teacher called it 'the sound of induction'.

They also said that if the charge was too big, they would act as a fuse, and break.

I'm confused now. I trust you SD, but I also believe my college teacher.

This needs some investigating! haha

I'll check with one of my room mates. He's doing his phd in electical engineering.
