How to calculate the maximum capable power rating of the core of a inductor ?

I am trying to design a boost converter but I do not how to choose the core.

If the core is distributed gap type (such as powdered iron), it depends on the losses:

If the core is discrete gap (usually ferrite), the gap should be set to give an effective permeability of 10-100, depending.  The gap sets the inductivity (inductance per turns squared) and saturation current (amp-turns), proportionally, and independent of saturation flux (volt-seconds).
