Abstract: A computer-implemented method for simulating a magnetic field within an electromagnetic device for use in evaluating the electromagnetic device. The method comprises: obtaining a digital design of the electromagnetic device, the digital design comprising geometric data representing a geometry of the electromagnetic device and material data representing material properties of the electromagnetic device; obtaining magnetic field data representing a magnetic field pattern that would be generated through operation of the digital design of the electromagnetic device; and converting the magnetic field data into virtual current data, wherein the virtual current data represents the magnetic field pattern as one or more virtual currents that would create an estimated magnetic field pattern that substantially matches the magnetic field pattern.

Abstract: A system and method of sensing in a system, the system comprising: a plurality of sensors (2, 4, 6, 8); and a processor (1); wherein each sensor (2, 4, 6, 8) has a resonant frequency dependent upon the value of a physical quantity being sensed by the sensors (2, 4, 6, 8); at least one of the sensors (2, 4, 6, 8) has a different resonant frequency from another of the sensors for a given value of the physical quantity; and the processor (1) is adapted to discriminate between the resonant frequencies of the sensors. Each sensor (2, 4, 6, 8) may be a fluid level sensor. Also, the range of fluid levels sensed by a first sensor (2) may be different to that sensed by a second sensor (4), wherein the first of the sensors (2) has a different resonant frequency to the second of the sensors (4).
