5. Digital techniques / Electronic instrument systems

To deflect the beam of a CRT horizontally, coils are placed on the neck of the tube

  • left and right.
  • top and bottom.
  • diagonally opposite.

Explanation from PART66Online

Magnetic deflection acts at right angles to the field, so to move the beam horizontally the magnetic field must be vertical. A vertical field is produced by deflection coils placed at the top and bottom of the tube neck, which gives the required horizontal deflection of the beam.
