Just use some wire cutters or sharp scissors & cut (only until you feel wire)while you rotate around. Once you cut all the way around, pinch where you cut (carefully)with implement & pull off insulation. It takes a little practice,& occasionally you will go thru wire as well, but that's how it's done.
Magnetic wire has a coating of varnish for an insulation.
By "clear insulation," I assume you mean the type of wire used in some lamp cords. If so, the hot wire is the one with the smooth (non-ribbed) insulation.
The insulation will be green in colour. Also bare copper can be used as a ground wire.

They are for stripping the insulation off electrical wire.
The action of removing insulation for a wire is called stripping.
To refine copper wire scrap, you need professional tools and equipment such as copper stripper which is used for removing insulation from copper wire.

The insulation on a wire is applied after the wire is drawn to size.

Insulation?
Electrical insulation on a wire or cable composed of plastic. Most wires and cables use plastic insulation. Some other types of insulation used on wires and cables are: enamel, cloth, natural rubber, gutta percha, ceramic, etc.

So that the living organisms and other wires/metals are not affected by the current in a given wire. In the absence of insulation two wires coming in contact may cause short circuit and also there is a risk of death of the living organisms coming in contact. There is one more reason that insulation minimizes charge leakage from the wire.
Not that I know of. When insulation is applied to wire it is extruded so that the insulating material is uniform around the conductor. Without this uniformity the conductors insulation factor would vary and the wire would have to be rated at the lowest reading factor when tested with a high voltage. Even when splicing a wire, the electrical code states that the insulation covering the splice has to be brought up to or surpass the insulation factor that is supplied by the manufacturer of the wire.
