Sentences with phrase «direction of the magnetic field»

A compass is not made of the same substance as a magnetic field, nor is it sent or chosen by the north pole, but it is accurately sensitive to the pull and direction of the magnetic field within which we live.

The study shows that the initial direction of the magnetic field observed by Voyager 1 is deflected by the heliopause, like an elastic cord wrapped around a beach ball.

In this case, the magnetic coercivity (defined as the resistance to a change in the direction of the magnetic fields for a ferromagnetic material) of the nickel reveals insights concerning the transition of the vanadium oxide from being an electrical conductor to becoming an insulator, called the metal - insulator transition (MIT).

For example, the direction of the magnetic field in the device reverses direction every so often, as Earth's does.

All known magnets have both a north and south pole, as illustrated in the inset image, with lines indicating the direction of the magnetic field.

The direction of the magnetic field did not change however, suggesting the craft has not yet escaped the sun's clutches.

This modeling would be aided by observations that somehow capture the direction of the magnetic field within the CME as it leaves the sun and by «a better understanding of how the magnetic field will change and evolve as the CME makes its multiday transit from the sun to Earth,» Viereck says.

It turns out that the distance over which these flips occur depends on the direction of the magnetic field in that region of the neutron star, so that on one side, far more tau neutrinos will emerge from its hotter inner regions.

When the direction of the magnetic field is altered, then for a specific direction the orientation of the spin density wave also changes abruptly.

Passing a magnetic field through the SQUID moved the mirror slightly, and switching the direction of magnetic field several billion times per second caused it to «wiggle» at around 5 % the speed of light, a speed great enough to see the effect.

They lacked evidence of what they thought would be the key signature of interstellar space: a shift in the direction of the magnetic field.

When the direction of the current is reversed, the direction of the magnetic field reverses.

Tarduno and his team wanted hard data on both the intensity and direction of the magnetic field, which are recorded and stored in minerals, such as magnetite, at the time they were formed.

In my own work, which involves magnetic materials and their characterization in magnetic fields, I use a Hall probe to determine the strength and direction of magnetic fields.

The new work shows that materials hosting a type - II Weyl fermion have mixed behavior: While for some directions of magnetic fields the resistivity increases just like in normal metals, for other directions of the fields, the resistivity can decrease like in the Weyl semimetals, offering possible technological applications.
