magnetic filed is = mu*numberturns*current all that is given for the solenoid.
now that you know magnetic field B in the solenoid, then
force on the wire: currentinwire*length*B*sinTheta
A 550-turn solenoid is 15 cm long. The current in it is 33 A. A 3.0-cm-long straight wire cuts through the center of the solenoid, along a 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 field points due east?
