These lecture notes provide a
comprehensive introduction to Electromagnetism, aimed at undergraduates. Topics
covered includes: Introduction and Electrostatics, Magnetostatics,
Electrodynamics, Electromagnetism and Relativity, Electromagnetic Radiation,
Electromagnetism in Matter.
The goal of these guides is to
give students an appreciation of the major role magnetism plays on Earth and in
space, and ultimately enable them to use NASA data as “scientists” researching
our magnetic connection to the Sun. Topics covered includes: Permanent Bar
Magnets, Electromagnets, Jump Rope Generator, Induction in an Aluminum Can,
Geomagnetism, Space Weather Effects, The THEMIS Mission, Magnetism and
Measurement Techniques, The Fluxgate Magnetometer and The THEMIS Magnetometer.
In this book, the author give an account of some recent electrical
researches, experimental as well as theoretical, in the hope that it may assist
students to gain some acquaintance with the recent progress of Electricity and
yet retain Maxwell's Treatise as the source from which they learn the great
principles of the science.
