Material with low conductance such as rubber, plastics and so forth.
wood, crystal, diamond, stone, granite
Generically they are called conductors.
put a wire through it
yes
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
yes answer 2: No, magnetism can only pass through non magnetic materials.
Insulators
Electricity is unable to pass through them
Generically they are called conductors.
wood, crystal, diamond, stone, granite
Insulators are materials that don't conduct heat well, or (for electricity), materials that don't let electricity pass through them. In general they are non-metallic materials.
metals have the ability to pass and conduct electricity and heat through them....
Superconductors are materials that let current or electricity pass through them. Insulators are materials that don't allow current or electricity to pass through them. Superconductors are mostly all metals. Insulators are wood, plastic, and paper.
Insulation is keeping the heat inside, trapping it and not letting out. Conduction is letting a flow, such as electricity, pass through the material. for example, metal is a wonderful conductor of heat and electricity, but a bad insulator. However, wool is a good insulator and a bad conductor. :) hope that helps!

Metallic conductors such as copper, aluminum, silver and gold are some examples of materials through which heat and electricity can easily flow.
Metal mostly. Just to sum it up anything that is a conductor (except for the one that leads an orchestra)
All metals for example iron, copper, nickel. They are called conductors. Plastics and other elements do not, only metals. They allow electricity to pass through them because they have free electrons
