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
