Electrical Machines

  1. Building steel core out of stampings reduces eddy current loss because it
    1. increases core resistivity.
    2. increases the effective length of eddy current paths thereby increasing effective resistance to the flow of eddy currents.
    3. increases core permeability.
    4. reduces the effective length of eddy current path, thereby reducing effective resistance to the flow of eddy currents.
Correct Option: B

NA
