What about JFET? There is no such insulating layer between the gate and the channel.. Then?

I know FET offers a very high input impedance..but what's the reason behind it? Is it due to the reverse voltage applied at gate with respect to the source which makes the P-N junction reversed biased? If that the case, what happens when there is no voltage applied at gate?

And why do these planets show magnetism?

Why only Earth has a magnetic field around it and not other planets?

Unlike BJT, Why the minority charge carriers in FET do not participate in conduction? What is actually happening with the minority charge carriers?
