  • these core columns were made of z.
  • the purpose of these air gaps is to design and optimize the electromagnetic properties of the choke coils, so that the highest possible amounts of magnetic energy are stored in the air gap spaces, but the stray fields outside the air gaps or the insides of the windings are still kept low.
