A piece of insulated wire is shaped into a figure eight, as shown in the figure. For simplicity, model the two halves of the figure eight as circles. The radius of the upper circle is 3.00 cm, and that of the lower circle is 7.00 cm. The wire has a uniform resistance per unit length of 8.00 Ω/m. A uniform magnetic field is applied perpendicular to the plane of the two circles, in the direction shown. The magnetic field is increasing at a constant rate of 2.30 T/s.

**Diagram Explanation:**
The diagram shows a figure-eight-shaped wire with two circular loops. The upper circle has a smaller radius (3.00 cm) compared to the larger lower circle (7.00 cm). The field lines, represented by Xs, signify a magnetic field directed into the page and increasing in strength.

**Questions:**

(a) Find the magnitude of the induced current in the wire.
- Input provided: 0.021
- Feedback: "Your response differs from the correct answer by more than 100%."

(b) Find the direction of the induced current in the wire. (Select all that apply.)
- Options:
- Clockwise in the upper loop
- Clockwise in the lower loop
- Counterclockwise in the upper loop
- Counterclockwise in the lower loop
