hmmmm pls. post ans for this question pls I have got only one chance left. A solenoid has N=1863.0 turns, length d=46 cm , and radius b=0.4 cm, (b<<d) . The solenoid is connected via a switch, S1 , to an ideal voltage source with electromotive force ϵ=3 V and a ...

1. First of all, assume the z direction is what you get as the cross product of the x and y unit vector directions, using the right hand rule. The magnetic force will be in the i X B direction, which is the direction of the cross product of y and -x unit vectors. That will be ...
