Faraday's law Problem 9.7.1

Description

The animation shows a top view of four wires and a galvanometer in the lab.  Current flowing into the + terminal, i.e., counterclockwise, will deflect the meter to the right.   During the time interval t=2 s to t=8 s a magnet is slowly pushed completely through  the rectangle from the bottom toward the top. (You can also think of  the magnet as being pushed out of the computer monitor toward the user. Note: the magnet is not shown.) Observe the meter reading during this simulation.  

Question

Which pole was inserted first? North or south? The animation starts at t=0 and stops at t=10 seconds.    Start.

Answer

North.
