E6D08:

What is one reason for using powdered-iron cores rather than ferrite cores in an inductor?

  1. Powdered-iron cores generally have greater initial permeability
  2. Powdered-iron cores generally maintain their characteristics at higher currents
  3. Powdered-iron cores generally require fewer turns to produce a given inductance
  4. Powdered-iron cores use smaller diameter wire for the same inductance
