11 ) Develop and use models to illustrate electric and magnetic fields, including how each is created (e.g., charging by either conduction or induction and polarizing; sketching field lines for situations such as point charges, a charged straight wire, or a current carrying wires such as solenoids; calculating the forces due to Coulomb's laws), and predict the motion of charged particles in each field and the energy required to move a charge between two points in each field.

This video discusses the physics of electricity and Coulomb's law--it's time to talk about charge. What is charge? Is there a positive and negative charge? What do those things mean?

This Crash Course Physics video discusses electric fields and Coulomb's law. 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.

How do defibrillators you see on TV actually work? Physics can explain! In this video, Dr. Shini has the task of breaking down electrical potential energy, electric potential, voltage, capacitors, energy storage, and potential energy.

Electric current works somewhat like a river. Instead of flowing based on elevation, electric current works a little differently. In this episode of Crash Course Physics, Dr. Shini talks to us about electric current, voltaic cells, and how we get electric charge.

Magnets have a north pole and a south pole. Two of the same pole will repel each other, while opposites attract. Only certain materials, especially those that contain iron, can be magnets. There’s a magnetic field around Earth, which is why you can use a compass to figure out which way is north. In this episode of Crash Course Physics, Dr. Shini takes us into the world of magnetism.

Hans Christian Oersted had just discovered the connection between electricity and magnetism. Meanwhile, a French physicist named André-Marie Ampère was experimenting with some wires, trying to learn more about the connection between currents and the magnetic fields they create. Ampère would discover one of the most fundamental laws of electromagnetism. This video will discuss Ampère’s Law.

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

In this episode of Crash Course Physics, Dr. 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.
