Interaction Between Earth's Core and the Magnetic Field
Part I in the discussion What is the interaction between Earth's core and the magnetic field? Therese Moretto Jorgensen – National Science Foundation reports involvement in a satellite project studying the magnetic field around the Earth and it’s relationship with the Sun. Specifically studying how this affects the aurora. Run time 03:38.
Origin of Earth's Magnetic Field
Origin of Earth's magnetic field, new discoveries and new concepts, published in world-class scientific literature and explained here. Run time 09:34.
Magnets William Gilbert, personal physician by appointment to her Majesty Queen Elizabeth I of England, discovered that the earth behaves like a giant magnet. Magnetism as a natural phenomenon, the behavior of magnetic materials, and the motion of charged particles in a magnetic field.

All magnetic fields can be thought to be produced by electric currents. The relationship between a current and the magnetic field it produces is a little peculiar geometrically, and takes some getting used to. The law of Biot and Sarvart, the force between electric currents, and Ampere's law.
What happens when a speeding proton goes through a magnetic field. This video, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification.
This is Part 2 of the proton through a magnetic field problem.
Magnetism 6: Magnetic Field Due to Current
See how a wire carrying a current creates a magnetic field. This video, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 09:42.
Magnetism 9: Electric Motors
Using a magnetic field to exert torque on a rotating circuit. This video, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 10:36.
How do changes in Earth's magnetic field and ionosphere affect us?
Part 1 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Bob McCoy – Office of Naval Research. Storms and variations in the ionosphere impact Navy instruments, e.g, Suns storms (disturbances) can degrade GPS affecting ship navigation, airplanes, and all kinds of communication and transportation on Earth. Dish TV and satellite operations are also disrupted or impacted by this. Talks about the fun of flying rockets and studying the data to make new discoveries
How do changes in Earth's magnetic field and ionosphere affect us? - Part 3
Part 3 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Kyle Johnson – University of Colorado. Talks about meteor entry into the atmosphere (large flaming balls and little pieces of sand) leaving a trail visible on radar. They use the meteor trails to model affects on the lower atmosphere. Our daily lives depend on the Sun so it’s important in understanding the nature of that energy balance; it’s not a direct connection, but its all connected. He had al
This video is one of MEET ME AT THE CORNER's virtual field trips. A group of young girl inventors from San Diego enter FIRST Robotic competition. The girls answer various questions in this video interview. Run time 04:15.
Pinhole Photography for Kids
This is one of MEET ME AT THE CORNER' Virtual Field Trips. The video takes you to San Diego to learn about pinhole photography and demonstrated how to make your own pinhole camera. Run time 03:49.
17.951 Special Graduate Topic in Political Science: Public Opinion (MIT)
This course provides an introduction to the vast literature devoted to public opinion. In the next 12 weeks, we will survey the major theoretical approaches and empirical research in the field of political behavior (though we will only tangentially discuss political participation and voting). For the most part we will focus on American public opinion, though some of the work we will read is comparative in nature.
Why study the polar regions?
Why study the polar regions? Hugh Chivers – La Jolla Sciences. He invented a machine to measure the galactic radio noise that comes from our galaxy. The galaxy operates as a fixed radio signal transmitter in space. We are at the poles because the magnetic field of the Earth guides those particles coming from the Sun to the poles of the earth. Run time 02:39.
An Astronomer’s Window on the Birth of the Universe
Prof. Dobbs outlines the field of cosmology - the quest to understand the birth, evolution, and fate of the universe as a whole.
Island Universes: The Nature and Origin of Galaxies
Prof. Webb describes the basic characteristics of galaxies, outline the methods we use to study them, and highlights some of the main results and open questions in the field of galaxy formation and evolution.
