In this case, the magnetic field in the material is weakened by the induced magnetization.

Faraday applied a method in which a flow (the river flow) is exposed to a magnetic field (earth magnetic field) and the induced voltage is measured using two electrodes across the same flow.

The interplanetary magnetic field is much stronger than the dipole component of the solar magnetic field.

This is strands of magnetic field.

We live in a magnetic field.

It creates a magnetic field here.

The current creates a dynamic magnetic field.

We hold it with a magnetic field.

There will be a spinning magnetic field.

Semitry of Electric Field and of Magnetic Field by Pierre curie.

There aren't electric fields here. It's a magnetic field.

The zapper creates a magnetic field to counteract that.

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

Or maybe you switch the direction of the magnetic field.

Earth's magnetic field, rattling our planet's protective shell of magnetism.

Only a magnetic field greater than a certain intensity ( select ) can cause the core to change its magnetic polarity.

Each curtain consists of many parallel rays, each lined up with the local direction of the magnetic field, consistent with auroras being shaped by Earth's magnetic field.

The convergence of magnetic field lines towards the Earth that creates a magnetic mirror turns back many of the downward flowing electrons as the field strength increases.

Thus, when either field is changing in time, then a field of the other is necessarily induced.

When an electron is in motion, it generates a magnetic field.

This causes compression, heating, and a change in the magnetic field.

Well, one, I'll explain how we think about a magnetic field.

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

Number five, one of my favorites reversal of the Earth's magnetic field.

One methodology you could have used is you could have had the magnetic field going until you get to this point, and then you turn off the magnetic field, right?

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.

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.

So, if a moving magnet can create an electric field, this means that the moving electric field can create a magnetic field.

Variations in the Sun's magnetic field are carried outward by the solar wind and can produce magnetic storms in the Earth's own magnetosphere.

The solar dynamo is the physical process that generates the Sun's magnetic field.

And then what the effect of a magnetic field is on an electron.

They figured out how to keep Earth's magnetic field from penetrating the spacecraft.

Scientists think now our magnetic field may be diminished by about five percent.

Some species of ant are able to use the Earth's magnetic field for navigation.

Maybe you use some other contraption to switch the direction of the magnetic field.

And these strands of magnetic field inside the superconductor, they come in discrete quantities.

But what happens to the superconductor when we put it inside a magnetic field?

It's sort of surfing on a magnetic field at the crest of a wave.

In addition to moving perpendicular to the Earth's magnetic field, some magnetospheric plasma travels down along the Earth's magnetic field lines, gains additional energy and loses it to the atmosphere in the auroral zones.

In comparison, the magnetic field of Earth is roughly as strong at either pole, and its magnetic equator is roughly parallel with its geographical equator.

A current is induced in a loop of wire when it is moved towards or away from a magnetic field, or a magnet is moved towards or away from it, the direction of current depending on that of the movement.

This is strands of magnetic field. These are not particles, but they behave like particles.

The gauges will not read. They're all peaked, like we're plugged into some magnetic field.

It's as though you're moving an electrical wire through a magnetic field that generates current.

A moving wire in a magnetic field has its electrons pushed, creating an electrical current.
