Abstract
One embodiment disclosed herein is an apparatus for performing a thermodynamic cycle comprising: a sample that exhibits temporary magnetic remanence; and a magnetisation apparatus for magnetising the sample, wherein the magnetisation apparatus is operable, during a first part of the thermodynamic cycle, to produce a cyclically-varying magnetising field comprising a wavetrain of a single or plurality of consecutive cycles, and to remove the magnetising field from the sample during a second part of the thermodynamic cycle, wherein demagnetisation of the sample during the second part of the thermodynamic cycle causes the generation of an independent magnetic flux.

An apparatus for performing a thermodynamic cycle, comprising:
- a sample that exhibits temporary magnetic remanence;
- and
- a magnetisation apparatus for magnetising the sample, wherein the magnetisation apparatus is operable, during a first part of the thermodynamic cycle, to produce a cyclically-varying magnetising field comprising a wavetrain of a plurality of consecutive cycles, and to remove the magnetising field from the sample during a second part of the thermodynamic cycle,
- wherein demagnetisation of the sample during the second part of the thermodynamic cycle causes the generation of an independent magnetic flux.
A method of convening energy, comprising the steps of:
- providing a sample that exhibits temporary magnetic remanence;
- magnetising the sample, during a first part of a thermodynamic cycle, by producing a cyclically-varying magnetising field comprising a wavetrain of a plurality of consecutive cycles;
- and
- removing the magnetising field from the sample during a second part of the thermodynamic cycle, thereby allowing the sample to demagnetise, the demagnetisation of the sample causing the generation of an independent magnetic flux.
An apparatus for performing a thermodynamic cycle, comprising:
- a sample that exhibits temporary magnetic remanence;
- and
- a magnetisation apparatus for magnetising the sample, wherein the magnetisation apparatus is operable, during a first part of the thermodynamic cycle, to produce a substantially sinusoidally-varying magnetising field, thus producing a substantially sinusoidal variation of magnetic flux in the sample, and to remove the magnetising field from the sample during a second part of the thermodynamic cycle,
- wherein demagnetisation of the sample during the second part of the thermodynamic cycle causes the generation of an independent magnetic flux.
A method of converting energy, comprising the steps of:
- providing a sample that exhibits temporary magnetic remanence;
- magnetising the sample, during a first part of a thermodynamic cycle, by producing a substantially sinusoidally-varying magnetising field, thus producing a substantially sinusoidal variation of magnetic flux in the sample;
- and
- removing the magnetising field from the sample during a second part of the thermodynamic cycle, thereby allowing the sample to demagnetise, the demagnetisation of the sample causing the generation of an independent magnetic flux.
