Magnetic vector potential
The magnetic vector potential (A? ) is a vector field that serves as the potential for the magnetic field. The curl of the magnetic vector potential is the magnetic field. B? =?×A? The magnetic vector potential is preferred when working with the Lagrangian in classical mechanics and quantum mechanics.


Magnetic Flux Density (B)
Magnetic flux density is defined as the amount of magnetic flux in an area taken perpendicular to the magnetic flux's direction. An example of magnetic flux density is a measurement taken in teslas.

Current Density (J)
the amount of electric current flowing per unit cross-sectional area of a material.

Electric Field INtensity (E)
Electric field intensity is the strength of an electric field at any point. It is equal to the electric force per unit charge experienced by a test charge placed at that point.


Electric Potential V
An electric potential (also called the electric field potential, potential drop or the electrostatic potential) is the amount of work needed to move a unit positive charge from a reference point to a specific point inside the field without producing any acceleration.

You hold a wire coil so that the plane of the coil is perpendicular to a magnetic field vector B. Vector Bis kept constant but the coil is rotated so that the magnetic field, vector B , is now in the plane of the coil. How will the magnetic flux through the coil change as the rotation occurs? Check all that apply. The flux is unchanged because the magnitude of vector B is constant. The flux increases because the angle...

Magnetic flux lines, by itself, is not very useful. You can’t see them. You can’t touch them. They can’t be detected by sensors. So, by themselves, they are not very useful. Yet, as a concept they very useful. But within a context, when they are changing in time, in the vicinity of other things (what things?) they are important. Explain where Magnetic Flux is useful, where it is important?

If the magnitude of \(\vec{B}\) increases while its direction remains unchanged, how will the magnetic flux through the coil change?
If the magnitude of \(\vec{B}\) increases while its direction remains unchanged, how will the magnetic flux through the coil change? Check all that apply. The flux is unchanged because the position of the coil with respect to \(\vec{B}\) unchanged. The flux increases because the magnitude of \(\vec{B}\) increases. The flux decreases because the magnitude of \(\vec{B}\) increases. The flux is unchanged because the surface area of the coil is unchanged.
