Homework Help: Induced Current Problem

  1. Oct 28, 2008 #1
    1. The problem statement, all variables and given/known data
    A magnet is dropped down each the copper and glass tube. What direction is the induced current in the copper and glass tube respectively?


    a)clockwise, clockwise
    b)clockwise, no induced current
    c)counter clockwise, clockwise
    d)counter clockwise, no induced current

    2. Relevant equations
    None are necessary.

    3. The attempt at a solution
    I think the answer is b) clockwise, no induced current. Using the left hand rule the direction of the magnetic field in the copper tube is upwards and the direction of the current is clockwise. Current cannot be induced in a glass tube. Am I right?
