10) Two long thin parallel wires 13-cm apart carry 28-A currents in the same direction. Determine the magnetic field
vector at a point 10-cm from one wire and 6-cm from the other as seen in the figure below.

11) A thin 12-cm-long solenoid has a total of 460 turns of wire and carries a current of 2-A. Calculate the field inside
the solenoid near the center.
12) A 550-turn horizontal solenoid is 15-cm long. The current in its coils is 38-A. A straight wire cuts through the
center of the solenoid, along a 3-cm diameter. This wire carries a 22-A current downward (and is connected by
other wires that don't concern us). What is the force on this wire assuming the solenoid's magnetic field points due
east?
