Question
Rather than letting the loop fall downward in the figure(Figure 1) , suppose we attach a string to it and raise it upward with constant speed along the path indicated by the dashed line.
Part A: Is the tension in the string greater than, less than, or equal to the weight of the loop when the loop is below the magnet?
Part B: Is the tension in the string greater than, less than, or equal to the weight of the loop when the loop is above the magnet?

Part B: Is the tension in the string greater than, less than, or equal to the weight of the loop when the loop is above the magnet?Explanation / Answer
A)the tension is greater because by lenz law, the magnet repels the ring and hence it experiences a force in the downwards direction and hence tension is greater
b)tension is tension is again greater due to the same reason but the flux is just decreasing in this case
