Abstract
Procedimiento para crear regiones imanadas en un material magnético para tubos de rayos catódicos, cuyas regiones imanadas producen un campo magnético de movimiento de los haces electrónicos para mover por lo menos un haz electrónico dentro del tubo de rayos catódicos de una forma predeterminada, caracterizado por la primera fase de desarrollar un campo imanante apropiado que imana zonas magnéticas dentro del material magnético para crear las regiones imanadas y producir el campo magnético de movimiento de los haces electrónicos; y la segunda fase de eliminar del campo magnético de movimiento de los haces electrónicos un componente contribuido por zonas magnéticas de desimanación relativamente fácil dentro de las regiones imanadas estabilizando por lo tanto las regiones imanadas y evitando que se produzcan cambios sustanciales en los valores del campo magnético de movimiento de los haces electrónicos.
