(1) If we move the magnetic field sensor from the center of the coil to the radial direction, how should the magnetic field be changed?
☞ Solenoid that we use in experiment is not infinity. If the length of solenoid is infinity, magnetic field density inside of solenoid is uniform. However, because it isn't infinity, magnetic field density inside of solenoid isn't uniform. So, if we move the magnetic field sensor from the center of the coil to radial direction, magnetic field density changes and the magnitude of magnetic field maybe change. In center of the coil, there isn't a great differnce. But in outside of coil, a magnetic line of force decreases when closing the center axis. Therefore, from the center of the coil to the radial direction, magnitude of the magnetic field maybe increase.

(2) What's the difference of the magnetic field between at the center of the coil and at the one end of the coil.
☞ At the optional point O on the center axis of solenoid the magnitude of magnetic field is . Then, at the center magnitude of magnetic field is . So . At the one end of the coil, . So . Throug this two equation, the magnitude of magnetic field at the center of the coil is times bigger than at the one end of the coil.
