Electricity and Magnetism -Magnetism

When an electric current flows through a coil of wire, a magnetic field is produced. This relationship between electricity and magnetism is called electromagnetism. The magnetism of an electromagnet can be controlled by switching the electric current on or off. Electromagnets are used in many devices including computers, doorbells, and cranes that pick up heavy […]

What Is the Difference Between Electric Potential Energy and Electric Potential? | Physics in Motion

♪♪(Anzar) Look at all that water.Just think about the energy that is stored in there,ready to do work.That form of energy is called gravitational potential energy,stored energy that gravity can turn into kinetic energy.When it does become kinetic energy,it can be converted to hydroelectric powerthat can heat homes, restaurants and stores,and run computers.But gravity isn’t […]

Energy & Electricity in Science : How Is Nuclear Energy Produced?

Hi I’m Steve Jones, and I’m going to briefly tell you how nuclear energy is produced. Now obviously this is not a drawing of a nuclear power station, simply because it’s a very complex thing. But it’s actually a very simple process. Withing the nuclear reactor at the center you have the reactor itself, which […]

Pith Ball and Plastic Rod Attraction and Repulsion

When a plastic rod is rubbed on a piece of fur, it tends to gain electrons according to our modern interpretation of atomic theory. And the animal fur tends to lose those electrons Therefore when pulled away, this plastic rod is negative ’cause it has excess electrons and the fur is positive because it has […]

Polarization of Paper Dots with Charged Plastic Rod

These are a bunch of little holes from the hole puncher that I just dumped out on the table. And so they’re neutral, they’ve been sitting around not doing much at all. What I’m gonna do is charge up a plastic rod negatively by rubbing it on a piece of fur, and then bringing it […]

Electric Potential, Current, and Resistance

Hey it’s professor, Dave let’s learn about electric potential. We now know about the electric force and the electric fields that propagate this force, so how is this useful to humans? To answer this we must understand that just as there is gravitational potential energy by virtue of an object’s position in a gravitational field, […]

21. Class 12th Physics | Terrestrial Magnetism | Tangent Galvanometer | by Ashish Arora

let us now study an important experimental setup. which we call tangent galvanometer. we can write that this is the device. for which we can say this is used. to measure. horizontal component. of. earths magnetic field. we can also write that any point. on earth surface. where this device is used. lets first discuss […]

Electrostatic Induction

Hi. It’s Mr. Andersen and this AP Physics essentials video 72. It is on electrostatic induction, which is the ability of charges in one object to affect charges in another object. And so an example of this is static electricity. And so as this child went down the slide, friction of their hair on the […]

What do I do here? You just take your foot and press down hard. When you enter the production area, you have to put on some special shoes in order to protect the electronics from electrostatic discharge. And they have a conductive strip here, so you put it on your shoe and put the strip […]

Top 10 Reasons the Universe is Electric: #1 Cosmic Magnetic Fields | Space News

Welcome to Space News from the Electric Universe, brought to you by The Thunderbolts Project™ at Thunderbolts.info For the last 5 years on this series we have presented a vast library of evidence for the role of electromagnetism throughout the cosmos. Though institutional science still insists that gravity is king, gravity-centric cosmology has faced an […]
