“You, Me, Electricity” (After the trip)


As you can see in our last publication which talks about “You, Me, Electricity”, one area of NEMO museum, we only talked about one subject cellular phone communication”. So when we went to the museum we realized that in this area there wasn’t only information about it, there, there were also information about radio, compasses… and now we would like to explain you more about it:

Electrical revolution step 1 – 1820



Discover how electricity moves a compass needle without touching it.
When you flip the switch, electricity starts to flow through the wire. The electricity turns on thre lamp and a magnetic field is created around the wire.
The needle, which usually points north, is now attracted by this stonger magnetic field.
You can use this system to communicate if you agree a code beforehand but the receiver can't response you.

*We would like to tell you that we also add photography in our last publication of NEMO museum. We wish that it likes you.
