1. The problem statement, all variables and given/known data
Two coils are place on an iron heart, like in the picture. The top Coil is connected to a galvanometer, the second could be connected to a power source.
2. Relevant equations
Will an electric current flow through the top coil when:
a) connecting and then disconnecting the DC chain that the bottom coil is connected to.
b) connecting the bottom coil to a DC source.
c) connecting the bottom coil to a AC source.
d) removing the top coil upwards from an iron heart, when the bottom coil is connected to a DC source.
e) removing the iron heart upwards, when the bottom coil is connected to a DC source.
In all cases briefly explain Your answers.
3. The attempt at a solution
