Abstract
In this thesis experiments are conducted on a pipe which is filled with conducting liquid.
Alternating current flows through it and the resulting magnetic field induces voltages in the coils placed concentrically around the pipe. These voltages are measured and used to estimate basic parameters of the current distribution in the pipe.
The experimental setup is a product of a former thesis and was originally used to explore the possibility of determining the position of this pipe by observing the induced voltages.
Now the next step is taken and the influence of non-conducting objects placed in the fluid on the measured voltages is examined.
At first, a non-conducting rod is placed in the liquid and the resulting voltages are observed. Then a dimension is added to the problem and the rod is replaced by a ball.
In addition to the experiments, simulations and calculations are conducted and compared to the measurements.
At last, the ball is lifted during measurement and its speed is determined from the measured voltage.
