unusual facts about flux density



Laplace transform

The wide and general applicability of the Laplace transform and its inverse is illustrated by an application in astronomy which provides some information on the spatial distribution of matter of an astronomical source of radiofrequency thermal radiation too distant to resolve as more than a point, given its flux density spectrum, rather than relating the time domain with the spectrum (frequency domain).

The power loss, permeability, apparent power, flux density, magnetic field, Barkhausen noise, magnetostriction characteristics of soft magnetic materials and hard magnetic materials can be measured with a range of test systems under DC, AC and rotational magnetising conditions.
