For Problems 2 to 4:
Figure shows a resistive loop with resistance of 2 Ohms. Magnetic flux density in this region is,,,,,,,,,, .
Problem  <10 points> Calculate the total flux — passing through the surface of this loop at t s =1 .
Problem  <10 points> Calculate the current on this loop at t s =1 .
Problem  <5 points> What is the direction of the current at t s =1 ? Clockwise or counter-clockwise?
