### Magnetic field intensity (H) flux density (B) THE JARGON

12/05/2017  Magnetic field strength is one of two ways that the intensity of a magnetic field can be expressed. Technically, a distinction is made between magnetic field strength H, measured in amperes per meter (A/m), and magnetic flux density B, measured in Newton-meters per ampere (Nm/A), also called Tesla (T). Magnetic flux density (B) is the quantity of magnetic flux (Φ)

### Magnetic field, field strength, and flux density

But actually "magnetic field" is perfectly valid as a description of either - both the magnetic flux density and the magnetic field strength are examples of a magnetic field. And just using "magnetic field" is a lot simpler ... so that's what we do most of the time on this site. If you think we're labouring this point a bit, it's because sometimes people have seen us use "magnetic field" and ...

### Magnetic field - Wikipedia

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.

### MAGNETIC FLUX CONSERVATION IN THE

06/04/2015  Similar to the magnetic field intensity and the radial velocity, the time-dependent magnetic field model accurately predicts the magnetic flux at V2, but not the order of magnitude decrease in magnetic flux at V1. We conclude that the drop in magnetic flux along V1 is not due to time-dependence of the solar wind source.
