Abstract
The invention relates to a deflection yoke ( ) for a cathode ray tube ( ) in which the energy for deflection is reduced. This is done by providing a magnetic material ( ) in voids ( ) that occur between the ferrite core ( ) and a set of frame coils ( ). The magnetic material ( ) is comprised in a preformed insert ( ), which may further comprise a rubber or plastic material. This results in a clean method of adding the magnetic material.
