Question
Near the center of a long solenoid, the magnetic field is a) always zero. b) parallel to the solenoid axis, independent of position, and proportional to the current in the coil. c) parallel to the solenoid axis and proportional to the current in the coil, but changes drastically with slight changes of position within the solenoid. d) parallel to the solenoid axis, independent of position, and independent of the current in the coil. e) perpendicular to the solenoid axis, independent of position, and proportional to the current in the coil.Explanation / Answer
c) parallel to the solenoid axis and proportional to the current in the coil, but changes drastically with slight changes of position within the solenoid.
