4. An outer metal ring surrounds an inner metal ring, as shown in the figure. The current in the outer ring is counterclockwise and decreasing. What is the direction of the induced current in the inner ring? A) clockwise B) counterclockwise C) There is no induced current in the inner ring.5. The wire in the figure carries a steady current I. What is true about the currents induced in each of the three loops shown? The wire and the three loops are all in the same plane. A B A) No current is induced in any loop. B) The currents are counterclockwise in all three loops. C) The currents are clockwise in all three loops. D) Loop A has clockwise current, loop B has no induced current, and loop C has counterclockwise current. E) Loop A has counterclockwise current, loop B has no induced current, and loop C has clockwise current.6. A wire along the z-axis carries a current of 4.9 A in the +z direction. Find the magnitude and direction of the force exerted on a 3.3-cm long length of this wire by a uniform magnetic field pointing in the -x direction having a magnitude 0.43 T
