    © 2016 IOP Publishing Ltd. Perpendicular ac susceptibility X = X' - jX′ of a superconducting long tape defined by magnetic moment and determined inductively by magnetic flux is calculated using Brandt's technique from a power-law dependence of electric field on sheet current density. The requirements of X measurements to the experimental setup and procedure are discussed based on the calculation results.
