Time dependant B fields

  1. Apr 19, 2005 #1
    How would I go about doing this problem? I have an infinitely long solenoid with a time dependant magnetic field inside. How can I find the E field?
    I've been trying something with Ampere's law, but I'm having trouble avoiding an infinite answer. Any insight would be appreciated. Thanks

    Hint #1: Do you know Faraday's Law?

    Hint #2: Why are you using Ampere's Law? You already have the expression for the B field right?

    Why don't you post the problem in its entirety?It would be much nicer to fomulate an opinion,if i knew what i was talking about.
