I found this simple but useful equation on a website for induction heating,
P = k.I^2.(u.p.f)^-0.5
where
P is the heating power to the workpiece
k is a constant
I is the current in the pick-up coil
u is the relative permeability
p is the resistivity (ohms mm^2/m)
f is the frequency
From this equation I want to work out the current in the pick up coil. I have values for all the parameters except the constant k.
Has anyone seen this equation before and know the value for the constant? Or does anyone know of other simple equations using similar parameters??
Does anybody know the value of this constant
