Two bar magnets A and B, and a non-magnetic bar C, all of same mass and dimensions, are dropped in an identical manner one by one through the center of a copper loop held horizontally (as shown in the figure). The times taken by the bars A , B , and C to reach the ground are t_A, t_B , and t_C , respectively. Which of the following relations is correct?

Options

  1. At_A t_B t_C
  2. Bt_A=t_B t_C
