Abstract

A method and system are described for determining the contribution of induced currents in the magnetic moment of a sample. The method comprises performing a first measurement of a first magnetic moment of the sample using a first magnetic field pulse wherein the magnetization of the sample is reversed and wherein the first measured signal contains contributions from a non- reversing change in magnetization and an induced current. The method also comprises performing a second measurement of a magnetic moment of the sample wherein the magnetization of the sample is not reversed and wherein the second measured signal contains contributions from a reversible change in magnetization and the induced current.
