Understanding Magnetism in Real Time

You're about to see magnetism in real

time develop right before your eyes

like magic.

Let's see another view of that cube magnet.

This is one of the poles.

Now, if I turn it sideways,

you'll see a slice

of the toroid of magnetism.

Let's have a look

at a ring magnet.

Let's have a view from the top.

And now, a view from underneath the viewer.

Next,

I have

a small grouping of small cube magnets.

As you can see, we're viewing the toroid,

which looks like-- think of it as a donut.

Okay?

One slice here,

one slice there.

Next, let's have a look

at a really large

donut magnet.

Remember, this is in real time.

So if I move

the magnet

and change its angle,

we're going to see

a real time update in the image.

Just like that.
