Figure 3 shows the circular cross section (diameter = 2 m) of a solenoid, which has 100 turns per meter and carries a clockwise current i of 3 A. The circular cross section lies in the x-y plane, where the +z axis is pointing towards you. A straight wire (length = 0.5 m) is placed entirely inside the solenoid, parallel to the y axis. The straight wire carries a current i of 2 A in the -y direction. (Hint: See the magnetic field due to a solenoid in EM Module 3.)
(a) What is the direction of the magnetic force on the wire.
