In this video Paul Andersen explains how contour lines show areas of equal elevation or equal gravitational potential. Contour lines are used as an analogy for lines of equipotential in electric fields.

Devices that collect data about our bodies need power, but they also might need to be very small or even ingestible. To avoid including batteries in these cases, researchers are looking for ways to harvest energy from the body itself.

As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating and a crucial part of physics. In this episode of Crash Course Physics, Shini chats about capacitors,...

In this video Paul Andersen explains how electromagnetic induction occurs when the magnetic flux of an object changes. The magnetic flux is product of the surface area perpendicular to the magnetic field and the magnetic field strength....

Not only do they describe every electrical and magnetic phenomenon, but hidden within these equations is a fundamental truth about the nature of light, and why it is the ultimate speed of the universe. We...

A bisected grape in the microwave makes plasma. But how does it work? A grape is the right size and refractive index to trap microwaves inside it. When you place two (or two halves) close together the fields interact with each other...

In 1897, J.J. Thomson conducted an experiment that led to the discovery of the electron and revolutionized atomic theory by demonstrating that atoms are composed of smaller subatomic particles. Before this, atoms were considered...
