Let's say I have a field (electric or magnetic or something) and it's time-varying so I choose to represent its components as phasors.
Say the field is:
[tex]\vec{F} = X\hat{x} + Y\hat{y} + Z\hat{z}[/tex]
where, X, Y and Z are complex numbers.
Now, I want to find the amplitude of the field. If X, Y and Z were real (time constant field), I'd just go:
[tex]F = \sqrt{X^2 +Y^2 +Z^2}[/tex]
but I have no idea what to do here. Also, I'm not sure if there's an easy way to do this or not. Any ideas?
