TED-Ed: Magical metals, how shape memory alloys work - Ainissa Ramirez
From robots to braces to the Mars Rover, see how a special kind of metal called shape memory alloys advance technology in everyday ways that we don't always realize.

Registers and RAM: Crash Course Computer Science
Today we’re going to create memory! Using the basic logic gates we discussed in episode 3 we can build a circuit that stores a single bit of information, and then through some clever scaling (and of course many new levels of abstraction)...

Electromagnetism - Magnetic Force: The Four Fundamental Forces of Physics #4b
In this final segment on the four fundamental forces of physics, Hank tackles the magnetic force, the second of the two ways in which electromagnetism is apparent in the universe

Ampère's Law: Crash Course Physics
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...

TED-Ed: The neuroscience of imagination - Andrey Vyshedskiy
Imagine, for a second, a duck teaching a French class. A ping-pong match in orbit around a black hole. A dolphin balancing a pineapple. You probably haven't actually seen any of these things. But you could imagine them instantly. How...

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.

What Happens When You Get Electrocuted?
Most of the cases we call “electrocutions” are actually electric shocks: an electric current running through a body. Whether an electric shock becomes an electrocution depends on the nature of the current involved.

How to Make a Lemon Battery
Hank shows us another SciShow: Experiment! This time he's tackling what may be the most cliche, well-known and misunderstood experiment of all time: the lemon battery. The take home message in this one is: the electricity is NOT in 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...

Magnetism: Crash Course Physics
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...
