Problem
A narrow solenoid is mounted vertically so that its axis is along the vertical direction. A beam of electrons is sent horizontally towards the north through the centre of the solenoid. As soon as the electrons enter the region of the magnetic field inside the solenoid, the beam deflects towards the east. Which statement correctly describes the direction of current in the solenoid windings as viewed from above?
(a) anticlockwise
(b) alternating clockwise and anticlockwise
(c) clockwise
(d) cannot be determined from the information
