A solenoid is oriented so that its axis is vertical.Viewed from above, the current flows counter-clockwise around the solenoid.(a) Would a proton moving north inside the solenoid feel a force? If so, inwhat direction? If not, why not? (b) Would a proton moving upward feel aforce? If so, in what direction? If not, why not?
It is desired to construct a solenoid that will have a resistance of 6.00 Ω (at 20° C) and produce a magnetic field of 5.00x10−2 T at its center when it carries a current of 6.00 A. The solenoid is to be constructed from copper wire having a diameter of 0.500 mm. If the radius of the solenoid is to be 1.00 cm, determine (d) the overall length the solenoid should have.
