Computer Modeling and Measurement of Extended Technical Magnetic Field
Abstract
A personal computer was used for both themeasurement and modeling of technical magnetic fields in
different areas. The field modeling uses basic physical laws
from magnetism in the integral form and is performed by
the numeric integration in MATLAB. The apparatus is able
to measure a relatively low magnetic field. Important results
are presented for the measurement of the DC field in the
electromagnetic flow meter and AC field in the distribution
point. Only simple models were applied, nevertheless the
agreement with the experiment is good. Deviations are due
to inaccuracies both in the production and experiment,
predominantly. Their sources are not simple models.
Therefore, the models are applicable for reliable design or
analysis of devices using magnetic field.
