Abstract:
The aim of this paper is to present a way of visualisation of the magnetic
field created by permanent magnets or wires and loops carrying direct current.
Visualisation is achieved by using so called magnetic field viewer - a special
magnetic sensing film. Except visualisation of the magnetic field around the
magnetic object, measurements of magnetic flux densities are performed using
a Hall sensor. Also, a number of simulations of coils carrying direct current
in FEM software have been made in order to check a validation of the visualisation
effects obtained. The paper shows photographs of visualised magnetic
fields and the results of measurements and simulations, as well as a proper
discussion.
