  18. An introduction to the air cored coil

    Sometimes the purpose of an air coil is not to possess inductance but to create a region of space having a definite magnetic flux density. A well known example of this is the deflection coils placed around a cathode ray tube where the direction of the electron beam is controlled by the current driven through the coils.

  19. Why does coil density affect magnetic field magnitude? -

    Mar 12, 2017 · If you are asking what I think you are asking, them simply because each coil (loop) adds its magnetic field the ones around it the total strength of the field is thus the strength of each coil times the number of coils. Here is a link to a page density of coil coil
