I've got two magnets.

It uses magnets for propulsion.

So we're all familiar with a magnet.

My daughter attracted me like a magnet.

And those magnets will be used to focus electrons either through an image or bouncing it off an image.

And there's another notion of magnetic north.

If I were to take this magnet, this one right here, and if I were to cut it in half, somehow miraculously each of those halves of that magnet will turn into two more magnets.

Now, you see the magnet fell really slowly.

So that might be magnetic north.

But in general, when most people refer to magnetic north, or the north pole, they're talking about the geographic north area.

One does not simply turn on a pussymagnet.

Now, how do you work this Pussymagnet?

And magnetic south, I don't know exactly where that is.

That's an order of magnitude, up or down.

Or another way to put it, if we have a magnet, the direction of the magnet or the side of the magnet that orients itself if it's allowed to orient freely without friction towards our geographic north, we call that the north pole.

The south pole of my magnet here is going to be attracted to Earth's magnetic south.

So, we have quantum locking and we can levitate it on top of this magnet.

Words... word, word, word... word, word, word, word, word, word, word...

We're sieving the material, we're using magnets, we're using air classification.

So if this is a magnet, we know that a magnet always has two poles.

Now, the next thing I'm going to do is take these magnets and glue it in the center of this dot.

Magnetic north is the geographic location, where the north pole of a magnet will point to.

Now, I can extend this circular magnet, and make whatever track I want.

DG Here we see a monopole magnet in LHC Sector 7G.

And that if I were to flip this magnet around, it would actually repel north two north facing magnets would repel each other.

But it wasn't until the 1800's that finally we began to unlock the second great force which rules the universe the electromagnetic force.

The magnet then pushes electrons in a wire, and that's why electricity lights up in your bicycle lamp.

Talk.

But with the pendulum, it allows me to manifest these invisible forces that are holding the magnets up.

The equilibrium rotation rate varies directly with the flow velocity and inversely with the distance between the magnet and the duct.

Because the magnetic spins, or the magnetism created by the electrons are all canceling each other out, because it's random.

I'm going to take 30 gauge magnet wire and I'm just going to wrap it tightly together, and I'm going to do about 150 turns on a 3 4 inch wooden dowel.

like that silver one there, that was the result of hundreds of experiments with magnets, trying to find a way to make something float with the least possible connection to the ground.

You won't be surprised to hear that if I take this circular magnet, in which the magnetic field is the same all around, the superconductor will be able to freely rotate around the axis of the magnet.

He talked. He talked, Mama.

A current was allowed through a wire suspended from a pivot above the magnet and dipped into the mercury.

And so we have this notion, just like we had in electrostatics, that a magnet generates a field.

Copper has been used in electric wiring since the invention of the electromagnet and the telegraph in the 1820s.

The leading theory suggests that lodestones are magnetized by the strong magnetic fields surrounding lightning bolts.

It's a process that not only happens in the biological and chemical world, but is a phenomenon that can be seen from magnets to snowflakes, robotics, social networks, the formations of cities and galaxies, to name just a few.

DG Beam sensors have detected that an unknown event caused this magnet to quench and triggered an uncontrolled shut down.

Chief, you speak up now. Yes, Chief, you speak.

Speak up!

Go ahead.

So talk.
