| Summary: | AC and DC magnetic field measurements require a highly sensitive and
stable magnetic sensor. In order to achieve these requirements, good properties and
criteria of magnetic materials are identified. A few types of different magnetic
materials have been used to study their characteristics and effect towards magnetic
fields. The ring cores made from several different types of magnetic materials are
designed having the same dimension so that they can be compared among each
magnetic material easily. For this project, single and dual rod cores have been used
as a fluxgate sensor core to observe the resulting sensor performance. Both sensors
are tested with two magnetic sources; permanent magnet bar and solenoids with
different diameters of wires. The output of each fluxgate sensor was processed to
identify their relation with the test magnetic field density. |
