## Main Question or Discussion Point

Hi,

I'm just wondering (theoretically), about calculating magnetic opperating point for an inductor. Say permetivitty mu is 'u', N turns, A area, l is length:

Inductance L = u.N

Then do you need to worry about saturation? Or can you just wrap as many turns around it as you want for a massive inductance? As per that formula.

Is an inductor different to a transformer in that you don't need to worry about a magnetising curve for a type of steel?
