I am performing an experiment for school investigating the magnetic force of a solenoid. While doing this experiment I realized that I needed to connect the solenoid to the DC output of the power supply instead of the AC.
I am perplexed since for current induction, fluxtuations in the magnetic field are needed. I thought this would be the same "the other way round", i.e. using a fluxtuating current to create a magnetic field.
