10) As the loop approaches the green wire, but before it crosses over it, what happens to the induced voltage?
Added by Victoria G.
Step 1
Step 1: As the loop approaches the green wire, the magnetic flux through the loop begins to change because the current in the green wire produces a magnetic field. Show more…

Suppose the loop now moves in the positive y-direction as shown. What is the direction of the induced current now? The current flows counterclockwise The current flows clockwise There is no induced current now

8) A flexible loop of wire lies in a uniform magnetic field of magnitude B directed into the plane of the picture. The loop is pulled as shown, reducing its area. The induced current flows a) downward through resistor R b) upward through resistor R c) there is no induced current 9) The loop of wire is being moved to the right at constant velocity. A constant current I flows in the long, straight wire in the direction shown. The current induced in the loop is a) clockwise b) counterclockwise c) there is no induced current

(II) $(a)$ If the resistance of the resistor in Fig. $21-48$ is slowly increased, what is the direction of the current induced in the small circular loop inside the larger loop? (b) What would it be if the small loop were placed outside the larger one, to the left?
