A transparent electron-beam tube is mounted vertically. An electron gun at the bottom of the tube sends electrons upwards. Two magnetic pole pieces produce a horizontal magnetic field from the observer's left to the observer's right. The front wall of the tube is nearest the observer and the back wall is furthest away.
Determine whether the electron beam bends towards the front wall or the back wall of the tube.
Give a reason for your answer.
