Show affiliationsA novel experiment for characterization of liquid–solid interface deformation by measurement of magnetic flux density has been carried out. A single-axis fluxgate sensor is used to measure the distribution of radial- and z-components of magnetic field around a rotating cylindrical cell containing a solid copper cylinder with a sinusoidal surface and KOH solution above it. The signal from the magnetic sensor is collected by a data acquisition board and processed by fast Fourier transformation. The experimental results agree well with the theoretical predictions calculated by the finite element method, which reveals that the set-up is applicable to develop magnetic field tomography for reconstruction of interface deformation.
