Definitions

  • the coil heads I2 of the line deflection coils 9 and ID are bent upwards and bear on the terminal laminations of the core. With the aid of the sets of coils mounted in this manner it is possible to generate at the point of the cathode ray beam two homogeneous magnetic fields which are perpendicular to one another.
  • the lines of force of the magnetic field generated by the picture deflection coils extend through the pole shoes and the yoke of the iron core, the homogeneity of this field being promoted by the presence of the pole shoes.
  • the magnetic field generated by the line deflection coils extends, on the contrary, substantially through the air due to the heavy eddy-currents generated by this field in the iron of the core.
