They have different electrical and magnetic properties.

An electric current can generate magnetism.

If you line the sides of the cabinets using the gel material if a cabinet slams shut it wouldn't make a loud noise, and in addition the magnets would draw the cabinets closed.

It's because of this that you need the magnetic braking system.

So there's this huge invisible shape structures that magnetism takes in the universe.

They have either identical or very similar electrical and magnetic properties.

TS The magnetic works are a combination of gravity and magnetism, so it's a kind of mixture of these ambient forces that influence everything.

The augmented equations, today known as the Maxwell equations, described a unified theory of electricity and magnetism. The new equations showed that light is a moving, self renewing disturbance in electrical and magnetic fields, and they predicted that new kinds of disturbances are possible.

And these tin particles were deposited on the tape heads and were crashing the tape heads.

And we heard a little bit about functional MRI.

Here we go. Whoa! It's magnetic. It doesn't pull the laptop onto the floor.

JH Now is this electromagnetic here, or are these static?

The center was in the process of converting historical Landsat data from aging magnetic media to new cassette tapes to preserve them for future use.

Now when you're in an fMRI scanner, you're in a big magnet that's aligning your molecules in certain areas.

The first is zero electrical resistance, and the second is the expulsion of a magnetic field from the interior of the superconductor.

What's unexpected about this is that it's soft, but it's also a strong magnet.

And one of the unique capabilities that we leverage with the MR is the ability to measure temperature noninvasively.

This is an MRI MRA MRV, a volumetric MRI.

But how many fluxons, how many magnetic strands are there in a single disk like this?

This is the main method that I use. This is called functional MRI.

We're going to do it non invasively using MRI.

Create a startup disk using a CD or disc image

So what it actually does, it locks these strands, which are called fluxons, and it locks these fluxons in place.

And then what you do is, you start out with electricity, turn it into magnetic field, take that magnetic field, turn it back into electricity, and then you can use it.

Disks

It doesn't emit in the electromagnetic spectrum. It doesn't reflect.

One hundred billion strands of magnetic field inside this three inch disk.

Yousef Mohammed In other words, we're treating electricity with electricity, rather than treating electricity with the chemicals that we're using nowadays.

Disk Management

I buy tapes.

Screening the average young woman with an MRI is kind of like driving to the grocery store in a Hummer.

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.

KS So I'm sure all you engineers know that even though aluminum is a metal, it's not a magnetic material. But something unexpected happens when you drop a magnet down an aluminum tube.

One the soft properties of the magnet that make it so that, if it were to hit the rider in the head, it wouldn't injure him.

(c) To study the characteristics of the solar cosmic rays accelerated during solar flares and other activities, the conditions in which their emission occurs, their propagation in the interplanetary magnetic field and their influence on the magnetosphere of the Earth

And actually, the magnetic fields we're using are basically about the same as the Earth's magnetic field.

I've gone and had an fMRI myself, to see how my visual cortex is taking over.

(d) Audio and video cassettes, diskettes, microfiche slides and photographs, including negatives.

These are two magnets.

Mount Disk Images

(c) Mission IBIZA registration of the plasma accelerated in the geomagnetic auroral regions, interaction of ionized particles with the ionosphere and magnetosphere of Earth, creation of electromagnetic disturbances

As you're seeing this gel magnet for the first time, if you assume that all magnets had to be hard, then seeing this surprised you and it changed your understanding of the way magnets could work.

Doesn't matter if we turn the whole of space around by some angle, it doesn't leave the doesn't change the phenomenon of electricity or magnetism.

What I and my colleagues did was put 32 people, who were madly in love, into a functional MRI brain scanner.

This is a permanent magnet.
