EARTH'S MAGNETIC FIELD
This online lesson will be conducted by Piotr Stankiewicz, with the use of materials prepared by researchers from the Institute of Geophysics PAS: Paweł Czubak and Anne Neska.
Students will familiarise with the influence of geomagnetism on life on planet Earth and learn what the Earth’s magnetic field is, will define its sources, where the magnetic poles are and discover what actually tourist compass shows and under what conditions it shows falwed measurements. They will get acquainted with the term “magnetic declination” and learn how to calculate declination in a given year on the basis of available data from geomagnetic observatories. Calculations will be based, among others, on data from INTERMAGNET, an organization of geomagnetic observatories around the world. Students will also learn how to find the maximum and minimum value of the magnetic declination of the day; determine the declination for the date and for certain place; determine the difference between the declination determined from measurements and declination derived from calculator declination.
If you enrol for the webinar, in the section for enroled, you will find worksheets for students. Please, print them in advance and distribute. Students will have opportunity to actively fill in the tasks and calculate. Have fun!
