Homework Help: Electric field outside a solenoid

  1. Mar 17, 2014 #1
    1. The problem statement, all variables and given/known data

    A solenoid has a radius of 2.10 cm and 1180 turns per meter. Over a certain time interval the current varies with time according to the expression I = 1.30t, where I is in amperes and t is in seconds. Calculate the electric field 4.65 cm from the axis of the solenoid

    2. Relevant equations



    3. The attempt at a solution

    I have no idea where to start.

    I believe they are probably asking for the induced electric field caused by the changing magnetic field.

    Hello, MelanieB.

    I'm afraid the rules here at the forum require you to show some effort at a solution.

    Can you think of any laws or concepts that will help solve this problem?
