B Two loops of wire are aligned with a common axis (if you were to look through loop A, you would also be looking through loop B). There are no sources of EMF or magnetic field aside from these two wires. At the time we call t = 0, there is a constant current in wire B which points in the direction shown by the red arrow. After exactly one second, the current in wire B quickly stops. The current in wire B then remains at zero. Which of the following correctly describes what will happen in wire A at the point marked with the blue X? O When t = 0, there is no current in loop A. When the current in loop B stops, there is a brief current pointing up at the blue X. That current also quickly stops. O When t = 0, there is a current pointing up at the X. That current quickly stops when the current in loop B stops. When t = 0, there is no current in loop A. When the current in loop B stops, a current pointing down begins at the blue X and it continues until the current in loop B starts again. O When t = 0, there is a current pointing up at the blue X. When the current in loop B stops, the current in loop A also stops. O When t = 0, there is a current pointing down at the blue X. When the current in loop B stops, the current in loop A also stops. When t = 0, there is a current pointing down at the X. That current quickly stops when the current in loop B stops. When t = 0, there is no current in loop A. When the current in loop B stops, a current pointing up begins at the blue X and it continues until the current in loop B starts again.. When t = 0, there is no current in loop A. When the current in loop B stops, there is a brief current pointing down at the blue X. That current also quickly stops
