What Do You Learn When You Touch the Sun?
Though our Sun is something we can count on to rise and set each day, it also comes with some phenomena that can catch us by surprise: solar winds. To better predict when these winds will travel all the way to Earth, we sent the Parker...

What Makes Earth’s Magnetic Field Change Direction?
You might have heard that Earth is due for a complete flip of its magnetic field. And while our planet does have a history of this behavior, predictions of when it might happen are too complex to estimate a date for.

How Power Gets to Your Home: Crash Course Physics
In this episode of Crash Course Physics, Shini talks to us about how power gets to our homes. It's kind of amazing when you think about it and much more complicated than it may seem!

Vector Field
In this video Paul Andersen explains how a vector field shows the distribution of vector quantities. In AP Physics 1 student should be able to map and understand gravitational vector fields. In AP Physics 2 students should be able to map...

The How, Why, and How Much of Oil
Everyone does it -- using oil, that is. But how much do we have left? How do scientists find it? And where are they looking for it now that the easiest pickings have been taken? Hank has the answers to the how, why and how much of oil....

Magnetic Field of a Dipole
In this video Paul Andersen explains how current moving through a loop of wire can act as an analog for a magnetic dipole. Magnetic dipoles (like compass needles) respond to magnetic fields created by other magnets.

Induction - An Introduction: Crash Course Physics
In this episode of Crash Course Physics, Megneto helps Shini explain what induction is, how it works, and why magnetism is so seemingly complicated.

Electromagnetic Waves
In this video Paul Andersen details the characteristics of electromagnetic waves. Electromagnetic waves are transverse waves that can move through both mediums and vacuums. The electric and magnetic fields oscillate perpendicular to the...

Magnetic Field of a Wire
In this video Paul Andersen explains how current moving through a wire will generate a magnetic field tangent to the wire. As the current increases the magnetic field will increase and as the radius from the wire increase the magnitude...

Measuring the Magnetic Force
In this video Paul Andersen explains how a magnetic force arises when magnets or moving electric charges interact with one another. A magnetic dipole will orient towards a magnetic field. When an electric charge is moving it will...

Animal Magnetism: How Animals Navigate
Hank tells us about new research into the question of how animals navigate from place to place - while the problem is still unresolved, we do have some hypotheses, and they all involve something called "magnetoreception."
