Calculating the current in a solenoid

  1. Sep 28, 2011 #1
    1. The problem statement, all variables and given/known data

    A short-circuited solenoid of radius b with n turns rotates at an angular velocity
    about the diameter of one of the turns in a uniform magnetic field B. The axis of rotation is perpendicular to the magnetic field direction. The resistance and the inductance of the solenoid are equal to R and L, respectively. Find the current in the solenoid as a function of time

    2. Relevant equations

    Hint eq: phi = normal vector (dot) Magnetic field (B) s


    3. The attempt at a solution

    i cant seem to figure out where to start. in order to find the current in the solenoid, do i have to first start with finding the magnetic field (or a specific value of B)? and then plug that into the above eq?

    See the first page of,

    http://hyperphysics.phy-astr.gsu.edu/hbase/electric/farlaw.html

    There is a small error in the first page of the link above, can you find it?

    Once you get the induced sinusoidal voltage you can treat the problem as a series circuit consisting of a sinusoidal voltage a resistance and an inductor?
