A square loop with a resistor is in a magnetic field which varies in strength. Determine and explain the direction of the induced current (if there is one) in each case. Assume that the loop isnever moved outsidethe field.
a: The loop is moved straight to the right.
b: The loop is moved straight up.
d: The loop is moved straight down.
e: The loop is moved straight out of the paper.
f: The loop is moved straight into the paper.
