do you mean a magnetic core?
Power factor results from the inductive nature of a coupling system. To overcome thiis negative effect, capacitors are used to balance the inductivity. Usually sytems rated in VA shall be multiplied by a factor, often between 0.8 and 0.9, to calculate the usable power in Watts.
