1. A method of determining the temperature of an object, comprising the steps ofinducing an eddy current in a conducting member forming a part of or in operative thermal communication with said object,said eddy current induced by subjecting said conducting member to a magnetic field having a magnitude which varies substantially linearly over time, such that the corresponding eddy current magnitude changes exponentially over time;

  • determining a characteristic time constant of said current magnitude changes; and

    calculating the temperature of said object using said characteristic time constant.
