Steinmetz coefficient calculation

Hello,

I tried to calculate the Steinmetz coefficients as it was shown in another thread "Curve fitting", and I would like to know how to do a log-log plotting of the power density vs magnetic flux density.

I would like to see how accurate is the formula from my calculations and how well I can match with the graph from the datasheet.

Thank you!

Hello Werner,

Thank you. It works now.

Click on the expression for the x-axis (B) and chose "Logarithmic scaling" in the "Plot" Ribbon.

The n do the same for the expression for the y-axis (P(100,B)

Hello Werner,

Thank you very much for your reply.

I would like also to know how did succeed to represent on the same plot the line graph of P(100,B) and also the other graphical points in order to see how accurate is your Steinmetz equation?

Thank you!
