If a dc magnetic field is superimposed on the plasma, the basic equation of motion [Eq. (1)] now includes the magnetic field vector B, which will greatly affect the motion of the particles. First, the equation of motion will now be different depending on whether the component equation is parallel or perpendicular to the magnetic field.
Nov 30, 2017 1. At a point, a vector that represents the magnitude and direction of the magnetic field strength at that point. 2. In an electromagnetic wave, such as a radio wave or a lightwave, the vector that represents the instantaneous magnetic field strength in magnitude and direction at any point in a medium in which the wave is propagating.
The magnetic field at any point in space is a vector quantity. This means there is a direction associated with the field as well as a field strength. Consider the arrow below:
This magnetic field's strength and direction at a point are described by magnetic field vector. The closer we move the point to magnet, the denser is the field at the body. Thus, the length of magnetic field vector increases. magnetic field vector is also used in determining the force on a moving charge.
The quantity is known as the magnetic vector potential. We know from Helmholtz's theorem that a vector field is fully specified by its divergence and its curl. The curl of the vector potential gives us the magnetic field via Eq. . However, the divergence of has no physical significance.
May 01, 2010 Early Special Release Disambiguated Vector Magnetic Field Data. ReleaseNotes2: The first release of disambiguated full vector magnetic field data for science analysis took place in November, 2011. That release included 5-days of 12-minute vector magnetograms of AR 11158, the X-class flare producing region from February 12-16, 2011.
In the example we have just given, we have calculated the vector potential from the magnetic field, which is opposite to what one normally does. In complicated problems it is usually easier to solve for the vector potential, and then determine the magnetic field from it. We will now show how this can be done.

The net magnetization vector in MRI is the summation of all the magnetic moments of the individual hydrogen nuclei.. In the absence of an external magnetic field, the individual magnetic moments are randomly oriented and since they are in opposition, the net magnetization vector is considered to be zero.
magnetic ﬁeld superposition! just as the total electric ﬁeld at any point is the vector sum of the ﬁelds from all charges nearby,! so the total magnetic ﬁeld is the vector sum of the ﬁelds from all magnetic sources nearby.! Consider two solenoids producing nearly uniform ﬁelds:

The magnetic fields are governed by the magnetostatic approximation to Maxwell's equations describing electromagnetic phenomena. It is convenient to introduce a magnetic vector potential, A, such that the magnetic flux density vector B = ∇ × A.The solution procedure seeks a static magnetic response due to, for example, an impressed direct volume current density
This java applet is a magnetostatics demonstration which displays the magnetic field in a number of situations. You can select from a number of fields and see how particles move in the field if it is treated as either a velocity field (where the particles move along the field lines) or an actual force field (where the particles move as if they were little magnets).
