Inside the tubes are fixed rows of powerful permanent magnets. They generate a magnetic field, which is aligned in the direction of the substrate.

The first particles began striking Earth's magnetic field Friday afternoon.
And when they hit the Earth's magnetic field or any other planet's magnetic field, they interact with that field.
In 2.3 billion years from now, the outer liquid core of Earth will freeze, which means that Earth will lose its magnetic field forever.

An electric field and a magnetic field.
and we should all be extremely grateful for the hot metal soup down there because its constant churning generates enormous electric currents, which in turn create the magnetic field around the Earth.
But this gets weirder: our magnetic field sometimes actually just reverses.
These currents are heavily influenced by the rotation of the Earth, so the magnetic field they generate roughly aligns with the Earth's axis of rotation—but not precisely, and
This pole, together with the geomagnetic South Pole (which is on the exact opposite side of the Earth), represents the general overall trend of the Earth's magnetic field, especially as it extends into space.
We can't home for thousands of miles across open ocean just based on our perception of the Earth's magnetic field and things like that.
of the Earth's magnetic field, and things like that.
to establish precisely how the Earth's magnetic field interacts
due to changes in the magnetic field around the Earth
The first type of reactor uses a magnetic field to squeeze a plasma in a donut-shaped chamber where the reactions take place.
