Homework Help: Show that terminal velocity equals

  1. Mar 22, 2009 #1
    1. The problem statement, all variables and given/known data

    A conducting rectangular loop of Mass M and resistance R and length l and width w falls from rest into a magnetic field B as shown. During the time interval before the top edge of the loop reaches the field, the loop approaches the terminal speed v T .

    Show that Terminal velocity (Vt) = MgR

    2. Relevant equations


    3. The attempt at a solution

    HAve Nooooo Clue!
