10.39: A strong bar magnet is held very close to9 le kftk*hn n7q+juz+,kb8 6f the opening of a solenoid /ejc:*kbfn6rsa( cl/ as shown in the diagram. As the magnet is moved to the left toward the solenoid, a conventional current through the resistor shown is directed from A to B. What is the direction of the force on the bar magnet because of the induced current in the solenoid and which magnetic pole does the “??” in the diagram repre( jb6 / k/:crf*eclanssent?



A. Force on magnet is To the right Pole of magnet is North
B. Force on magnet is To the left Pole of magnet is North
C. Force on magnet is To the right Pole of magnet is South
D. Force on magnet is To the left Pole of magnet is South
E. Force on magnet is There is no force Pole of magnet is Can not determine
