Magnetism: Crash Course Physics #32

This episode was sponsored by Prudential. Go to and see how quickly 1% can add up.

You’re probably familiar with the basics of magnets already: They 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. And 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, Shini takes us into the world of magnetism!

Electric Current: Crash Course Physics #28

So, electric current works like a river... kinda... Instead of flowing based on elevation, electric current works a little differently. But it's a good metaphor. In this episode of Crash Course Physics, Shini talks to us about electric current, voltaic cells, and how we get electric charge.

Turning Magnetism Into Electricity (Electrodynamics)

Most of our energy isn't generated chemically like in batteries or by solar panels. Whether, it's coal, gas, nuclear, wind, or water power; it's generated by magnetic induction and governed by Faraday's law from electrodynamics.

The hidden link between electricity and magnetism

Have you ever wondered why the electric and magnetic fields are so closely connected? The unbelievable answer lies in special relativity. What looks like a magnetic field in a stationary frame of reference transforms into an electrostatic field in a moving frame of reference. I show you how to derive the strength of the magnetic field using only the equations of special relativity and electrostatics.

Voltage, Electric Energy, and Capacitors: Crash Course Physics #27

So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, everyone! Today, Shini has the task of breaking down Electrical Potential Energy, Electric Potential, Voltage, Capacitors, Energy Storage, and Potential Energy... it's a lot!

Magnetism

Magnetism: Let's learn about magnets! A magnet has 2 poles: North pole and South pole. Magnets have a special property to attract materials such as iron, steel, nickel and cobalt. Magnets can be of different shapes: bar magnet, horse shoe magnet, disc magnet. Properties of a magnetic field and magnetic field lines are discussed. We also look at a magnetic compass and the Earth's magnetic field.

Awesome Explanation of Electricity and Magnetism

I went through this subject in college inundated with equations and variables that pulled wool over my eyes. 30 years later, I understood the simple truth of this phenomenon after making Science Fair experiments for my kids: The Gauss Gun and the Shake Flashlight. Hence this video. This animated lecture-style presentation explains the empirical relationship between electricity and magnetism. See it and read it slowly and patiently before you get into equations in Physics class and clouding your mind with the complex works of the Physics masters. After all, they also started with the simple truth. Apologies for some slow animations, but don't let that or the classical music put you off. :o)

Electromagnets are incredibly useful. They can do all the things a normal magnet can do, but can also be switched on and off. Electromagnets have many uses, from moving cars in a scrap yard to high speed Maglev trains. The trains are suspended above the rails by strong electromagnets, reducing friction between the train and the track. And there are many, many other uses as well...

Electricity, Magnetism and Special Relativity - RSD Academy

Electric current causes magnetic fields and moving magnetic fields cause electric current...or do they? A magnetic field is actually the manifestation of how electric charges bunch up due to relative motion and special relativity.
