A cylindrical solenoid of 0.4m length has a diameter of 10mm and 250 tightly wound turns of wire uniformly distributed along its length. Around the middle of the solenoid is a 2-turn rectangular loop 3 x 2 cm2 in size, entirely made of resistive wire have a resistance of 150 Ohms. one microsecond after connecting the loose wire to the 9V battery to form a series circuit with the battery and the 20-Ohm resistor, what is the magnitude of the current in the rectangular loop and what is the direction?
