Solenoid in open circuit and with glavanometer attached

[tecktonik]

1.A student performs an expierment on a soenoid. The solenoid is open circuit in the first instance, the studet then pushes a magnet into one end with a constant force.

the second instance, the solenoid is connected to a galvanometer. Using the concept of energy conversion, relate and explain the results of her experiment.



2. No needed equations. Qualitative results needed.



3. I know it generates an emf, but doesn't it do the same thing in both?

Well you didn't give the results ...

why you think there wil be emf in second case
