This video is a lecture on magnetic fields. The speaker explains what magnetic fields are, how they look in the regions around magnets, and how to plot them on diagrams. The video also covers how the magnetic fields of two magnets in...

It explains the discovery of protons and neutrons and their characteristics.

This video explains the process of electricity generation on an industrial level. It describes how a voltage and current can be induced in a conductor by moving it relative to a magnetic field, and compares two types of electricity...

It explains construction of an electric generator and the working of an AC and DC generator and its differentiation.

In this video we explore what factors affect the size of the force on a wire carrying an electric current when it is placed in a magnetic field.

Magnets are highly misunderstood, and often interpreted as magic. But they're not magic! It's just science. Let's learn about what magnets are and what produces magnetism so that we can sound super smart at dinner parties, yes?

It explains the discovery of electrons by using the cathode ray discharge tube and the e/m ratio. It also shows how to find the charge of electrons.

This video explores five fun facts about magnets.

After a quiet half a century since the last Apollo mission landed on the moon, Associate Professor Alan Duffy takes us inside the new space race. What are the challenges for living for a long duration in space and how to mitigate health...

DC Motor explained - in this video we look at how does a dc motor work to understand the basic working principle of a DC motor. We consider conventional current, electron flow, the winding, armature, rotor, shaft, stator, brushes, brush...

How do Vacuum Pumps work. Vacuum Pumps Explained. In this video we learn how vacuum pumps work, the main parts of a vacuum pump and where we use them. This covered the basic working principle of single stage and two stage vacuum pumps...

Space weather has the potential to wreak havoc on everything from satellite communications to electric power. Sarah Gibson at the National Center for Atmospheric Research is studying the behavior of the sun to help warn against a serious...

AP Physics C: Electricity and Magnetism review of electric flux to understand magnetic flux, an example of magnetic flux through a current carrying wire loop, Gauss’s Law for Magnetism, electromagnetic induction, Faraday’s law, Lenz’s...

Solar winds are super fast, nuclear winds emitted by the sun. Were these winds to reach Earth's surface, they would cause a lot of damage. Find out what makes solar winds so dangerous andwWhat protects Earth from this weather.

Robert Lin, the late director of the Space Sciences Laboratory, discusses how NASA's MAVEN spacecraft will study the interaction of the Martian atmosphere with the solar wind. MAVEN's findings will reveal how Mars lost its early...

We only interact with the very surface of the Earth, called the crust. So what else is down there? What is the composition of the Earth? How many layers are there, and how do they differ? What is the mantle, and how does it convect? What...

Physical Science for Kids is the fun way to learn important facts about physical science and get ready for tests. Take a fascinating journey to the Super Science Station to learn about magnetic forces.

This nugget explains how a charge is affected by combined electric and magnetic fields. It explain in detail explanation of application of this phenomenon, the cyclotron.

For the first time in history, a spacecraft has touched the Sun. NASA’s Parker Solar Probe has now flown through the Sun’s upper atmosphere – the corona – and sampled particles and magnetic fields there.

This nugget explains the forces of attraction and repulsion between two current carrying conductors. It also explains the working of Roget's spiral to illustrate these phenomena.

New research has found evidence that Earth's magnetic poles have shifted rapidly once before, and could lead to a global catastrophe should it happen again.

In this video we going to give you an quick understanding on how electric motors work with some magnets and a wire

Magnets can be found in many objects that we use everyday. Not only are they located in man-made objects, but magnetic materials can be found in nature as well. In fact, the mineral, magnetite, was found to have magnetic properties long...

When we eventually develop the capacity to leave our solar system, we will be ready to visit countless other worlds. Where will we go first? Probably the closest system to ours, since it'll be the fastest. Which system is that? The Alpha...
