1. A planar coil arrangement for a magnetic induction impedance measurement apparatus, the planar coil arrangement comprising:

  • an excitation coil configured for generating a magnetic excitation field in an object, anda detection coil configured for detecting a magnetic response field generated in response to the magnetic excitation field inducing a current in the object, wherein the excitation coil and the detection coil are concentrically arranged relative to one another around a common center;

    the windings of the detection coil are arranged relative to the excitation coil such that currents induced in response to the magnetic excitation field comprise opposite signs, but similar amplitudes.
