A solenoid with N = 16 turns, length L = 0.30 m, and cross-sectional area A = 2.0 x 10 -3 m2 sits at an angle Φ = 30° with respect to a uniform magnetic field of magnitude B = 2.0 x 10-4 T, as shown in the figure. The solenoid carries a current I and experiences a torque of magnitude 6.4 x 10-9 N•m. What is the magnitude of I?
(a) 1.2 mA
(b) 0.6 mA
(c) 32 mA
(d) 2.0 mA
(e) 0.5 A
(f) none of the above
