Magnetic fields and emf

  1. Apr 14, 2015 #1
    1. The problem statement, all variables and given/known data

    What is the magnitude of the magnetic field inside the solenoid at t = 1 ms?

    2. Relevant equations

    Not sure

    3. The attempt at a solution

    Well I would make an attempt but firstly I have a question. What I want to know is the above question simply referring to the emf of the solenoid? Is the emf the same thing as the magnetic field? I cannot seem to find an equation relating magnetic fields and inductors.

    No, it is asking about the strength of the magnetic field, which is not the same as the emf.

    Right moments after posting this I found an equation for the B of a solenoid. I then found i for the inductor based on the given time and was able to find the stregth of B from that.
