In a CRT, if the magnetic field is parallel to the Y plates, what will be the direction of the electron beam movement?
- Diagonal.
- Vertical.
- Reversed.
Explanation
An electron moving through a magnetic field experiences a force at right angles to both its velocity and the field. With the magnetic field aligned parallel to the Y (vertical) plates, the resulting deflection acts on the beam to move it vertically. The motion is perpendicular to the field rather than along it.
bucks asking:
if the magnetic field is parallel to the Y axis why the movement of the beam is not horizontal? i know that the beam have to move in a direction that's perpendicular to the magnetic force lines...is it wrong?

Hi.
Magnetic field is parallel to Y plates, not Y axis. Y plates are installed in horizontal position.
