A solenoid is constructed having 350 turns of wire and is 62.0 cm in length. A single hanging wire is positioned vertically at the end of the solenoid so that a length of 6.0 cm receives the solenoid's full magnetic effect. The current through both the solenoid and the wire are set at 14.6 A. If the solenoid is positioned so that its magnetic field points to the wire and the current in the wire is vertical, what is the magnitude of the force on the wire?
