9. A solenoid passes through the center of a wire loop, as shown in (Figure 1). The solenoid has 1200 turns, a diameter of 2.0 cm, and is 7.5 cm long. The resistance of the loop is 0.072 Q. a. If the current in the solenoid is increased by 1.3 A in 30 ms, what is the induced current in the loop? Induced current B is increasing. Solenoid
