Project

2 axis HF-magnetometer using MFAM scalar mags and coils

Publisher

Supervisor

Location

Greater Copenhagen area

Project:

·        Build a two axis coil system with current control for cancelling the vertical and horizontal field.

·        Place a scalar magnetometer in both coils and measure the variation of the magnetic field in Z and H-direction.

·        Collect data at 1000 Hz and filter away noise. Use 1 hour data files or similar.

·        Develop program in Python to automatic filter data and plot spectrograms.

·        The HF-mag will be setup and tested at the geomagnetic observatory in Brorfelde.

 

 

Background:

The geomagnetic field are normally measured at 1 Hz to follow the low frequent changes in the field from daily variations to decades of years. Fluxgate magnetometers are normally used for this. But for other purposes it is interesting to measure at higher frequencies to find Schumann resonances or other fenomenances up to 40 Hz, and we are interested in this.

For this project we have a fast and sensitive double scalar magnetometer (MFAM from Geometrics). 

 

You:

- have an interest in geomagnetism and coil system

- can program in Python (or MatLab)

- can build Electronics

Requirements

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
