ELMs, Magnetic Xpoints, and Chaotic Fields Sugiyama, Linda E Abstract Edge Localized Modes (ELMs) in a magnetically confined plasma are shown to be a new type of nonlinear plasma instability, in which a coherent plasma structure couples to part of a chaotic magnetic field Numerical simulation using the M3D code 1 provides a detailed picture. Field is into the page 3 points (b) Assume that the only thing acting on the particles as they move through the magnetic field is the field As particle 1 moves through the field its kinetic energy increases decreases X stays the same The magnetic force is always perpendicular to the velocity There is no force component. Recently, the National Aeronautics and Space Administration (NASA) announced it had found actual portals in the Earth's magnetic fields The agency calls them Xpoints or electron diffusion regions that serve as uninterrupted paths to the Sun 93 million miles away Xpoints were found by NASA's THEMIS spacecraft and Europe's Cluster probes.

Another interesting way to look at magnetic fields is with magnetic field viewing film, ours is a piece 9 x 7 inches, from Arbor Scientific This material feels like a thin piece of semirigid plastic with paint on the back side In practice it acts like a sheet of green bubble wrap that has ultrafine bubbles filled with viscous fluid. Recent TCV experiments confirm the predicted formation of an electric potential well, below the magnetic Xpoint, in configurations with unfavorable B t field direction (ion ∇ B drift away from the divertor), that substantially reshapes the typical divertor E × B flow pattern The local charge balance ∇ ⋅ j in the private flux region (PFR) of diverted tokamak plasmas has been previously. These “X points” are thought to be hidden portals where the magnetic fields of Earth and the Sun meet, leading to the creation of a continuous path between them in the length of 93 million miles Physicists say that the “X points” are elusive, have a small size, and an unstable shape and may form and disappear completely at random.

Shortterm changes in the Earth’s magnetic field that occur over periods of just years or decades have now been shown in new research to have a very close relationship with changes in gravity The research focused on a specific area, stretching from the Atlantic to the Indian OceanIn this area, changes in the magnetic field correlate very closely with variations in gravity.

There's a pretty long catalogue of animals that appear to possess magnetoreception, or the ability to detect Earth's magnetic fields, including pigeons, dogs, trout, bees, turtles and salamanders. Portals form via the process of magnetic reconnection Mingling lines of magnetic force from the sun and Earth crisscross and join to create the openings "Xpoints" are where the crisscross takes place The sudden joining of magnetic fields can propel jets of charged particles from the Xpoint, creating an "electron diffusion region".

By Susanne Posel July 10, 12 from OccupyCorporatism Website Jack Scudder and his team of researchers at the University of Iowa have found "Xpoints" in the Earth's magnetosphere;. The classification and characterization of orbits in Poincaré plots is an analysis problem that arises in magnetic fusion simulations and experiments Devices, called tokamaks, enable physicists to perform experiments to determine the best shape for the hot reacting plasma and the magnetic fields necessary to hold it in place To complement the experiments, physicists also use computer.

The X markers indicate X points at which magnetic field lines reconnect The subscripts 1 and 2 indicate earlier and later evolution stages, respectively In the first scenario, in Figure 1a, FTEs grow due to pressure imbalance across the FTE boundary As the FTE is carried away from the subsolar region, the external magnetosheath pressure will. A magnetic field naturally generated by the Earth The magnetosphere is a protective magnetic buffer between the sun's radiation and solar winds and the earth's atmosphere. A timeindependent but spatially varying magnetic field B(x) points in the zdirection The magnetic field on the left side is B( xC − w / 2), and on the right side is B( xC w / 2) The electromotive force is to be found directly and by using Faraday’s law above.

Even in a collisionfree plasma, magnetic field lines that approach each other on a scale c / ω p e become indistinguishable during an evolution What is important is the different regions of space that can be explored by magnetic field lines that pass in the vicinity of null and Xpoints. Set to launch in 14, NASA is planning the Magnetospheric Multiscale Mission to study Xpoints or electron diffusion regions, places where the magnetic field of Earth connects to the magnetic field of the Sun, creating an uninterrupted path leading from our own planet to the sun’s atmosphere 93 million miles away A NASAsponsored researcher at the University of Iowa has developed a way for. As an efficient mechanism of energy release, magnetic reconnection is popular to explain many explosive events in extreme environments In some cases, however, we show the key concept of the magnetic X and O points is ambiguous, due to its noncovariant definition A simple model is constructed to study the case when the magnetic X point is disturbed by the inplane electric field.

Field lines resonate in a circular pattern from the magnetic north and south poles Compasses see magnetic fields and point in this direction The magnetosphere allows life to exist on Earth’s surface Without it, Earth would be exposed to cosmic and solar radiation from the sun Magnetic fields bend particles. “We call them Xpoints or electron diffusion regions,” explains plasma physicist Jack Scudder of the University of Iowa “They’re places where the magnetic field of Earth connects to the magnetic field of the Sun, creating an uninterrupted path leading from our own planet to the sun’s atmosphere 93 million miles away”. A magnetic field is a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable A magnetic field is produced by moving electric charges and intrinsic magnetic moments of elementary particles associated with a fundamental quantum property known as the spin.

The direction of the magnetic field lines is the direction of your curled fingers The magnitude of the magnetic field depends on the amount of current, and the distance from the chargecarrying wire The formula includes the constant This is called the permeability of free space, and has a value The unit of magnetic field is the Tesla, T.

The magnetic field of the Earth varies by location, but is estimated to be about 50 microtesla, or 500 times weaker than the magnetic fields used in the experiments. X Points the Way Where magnetic fields from two or more magnetically active regions are comparable in strength but opposite in direction, the fields deflect each other and a socalled X point forms The field strength goes to zero at the crossing point of the X Solar physicists think that at such points much of the action in the corona occurs. Scudder explains how these magnetic fields generate “Xpoints” Opposing fragmented lines of magnetic force from earth and sun crisscross, and join to create the portals at these Xpoints As imagined, these portals are invisible, unstable, and usually move—opening and closing with no warning.

3 points (a) Let us define positive flux as coming from magnetic field lines that are directed up through the loop Circle the graph below that best represents the graph of magnetic flux as a function of time for the magnet passing through the loop The field lines are directed down through the magnet at all times, which is the negative. As magnetic field gradients establish different precession frequencies across the imaging volume, evolution in a gradient over a specified time creates a spatial distribution of magnetization that varies along the gradient direction Greater amounts of evolution in the gradient produce progressively tighter spatial oscillations across the patient, or oscillations of progressively higher. Planetary magnetic fields are formed by the interaction between the convection of interior conducting material (molten rock and metal) and the planet’s own rotation Mercury’s field is weak because it rotates so slowly Venus doesn’t have an appreciable field because there appears to be little convection in its molten interior.

Electric Field due to a point charge E is a vector quantity Magnitude & direction vary with positionbut depend on object w/ charge Q setting up the field Efield exerts a force on other point charges r The electric field depends on Q, not q 0 It also depends on r If you replace q. The behavior of plasmas in configurations with magnetic null points is of potential interest for a number of systems Such nulls, sometimes referred to as Xpoints, a name strictly valid only for wellseparated nulls where magnetic separatrices cross at a right angle, may occur in only one component of the magnetic field, such as the poloidal field in a tokamak.

Figure 1 Magnetic field lines are defined to have the direction that a small compass points when placed at a location (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown away from the north pole of the magnet, toward the south pole of the magnet.

The viscous dissipation of axial field disturbances in planar magnetic Xpoints is examined It is emphasized that an accurate treatment requires a nonisotropic tensor viscosity whose components. “We call them Xpoints or electron diffusion regions,” explains plasma physicist Jack Scudder of the University of Iowa “They’re places where the magnetic field of Earth connects to the magnetic field of the Sun, creating an uninterrupted path leading from our own planet to the sun’s atmosphere 93 million miles away”. Using Polar data, we have found five simple combinations of magnetic field and energetic particle measurements that tell us when we've come across an Xpoint or an electron diffusion region.

A uniform magnetic field is represented by equallyspaced, parallel straight lines These lines are continuous, forming closed loops that run from north to south, and looping around again. “We call them Xpoints or electron diffusion regions,” explains plasma physicist Jack Scudder of the University of Iowa “They’re places where the magnetic field of Earth connects to the magnetic field of the Sun, creating an uninterrupted path leading from our own planet to the sun’s atmosphere 93 million miles away”. Magnetic reconnection is a physical process occurring in highly conducting plasmas in which the magnetic topology is rearranged and magnetic energy is converted to kinetic energy, thermal energy, and particle accelerationMagnetic reconnection occurs on timescales intermediate between slow resistive diffusion of the magnetic field and fast Alfvénic timescales.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, ch1 and magnetic materials A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field ch13 A permanent magnet′s magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. A process of magnetic reconnection is forming the portals Many lines with magnetic forces flowing and crossing eachother The crossing points of these Earth and Solar magnetic lines are creating the openings, the "Xpoints" The sudden junction of these magnetic lines cause a stream of charged particles coming from the nucleus of the Xpoint. The X markers indicate X points at which magnetic field lines reconnect The subscripts 1 and 2 indicate earlier and later evolution stages, respectively In the first scenario, in Figure 1a, FTEs grow due to pressure imbalance across the FTE boundary As the FTE is carried away from the subsolar region, the external magnetosheath pressure will.
