About the lecture

In this mini-lecture, we introduce the concept of magnetic fields. In particular. We consider: (i) natural magnets, where we see that like poles repel while opposite poles attract; (ii) magnetic field lines, which are always closed and describe the magnetic field strength depending on the density of lines; (iii) the magnetic field of an infinite wire carrying current; and (iv) the magnetic field lines of other current-carrying wires, such as a loop.

About the lecturer

Mohamed Anber is a Professor of Mathematical and Theoretical Particle Physics at Durham University. At the time of filming his course on magnetism, he was a Professor of Physics at Lewis & Clark College in Portland, Oregon in the United States. His research interests involve a broad range of theoretical physics topics, including those in quantum field theory and theoretical cosmology.
