Lenz's law

  1. Dec 1, 2009 #1
    when a current in a coil induces a current in another that is in series with it. Would the direction of the induced current change if the current falls?

    With Lenz's law the induced current would oppose the current of the first coil but what would happen to the induced current if the switch is opened? Does this change the direction of the induced current? Why? Please explain this.

    To induce an emf, current must be changing. Your original scenario is not clear. You may be confused.
