Any electrons flowing through a superconductor will show up as a regular electric current.
yes answer 2: No, magnetism can only pass through non magnetic materials.
Because insulators do not have free electrons as conductors in insulators electrons are very tight so its electrons do not allow electricity to pass through them!
It can't pass through because in insulators electrons are more tightly packed so there are no free space to pass through.
Conductors allow free electrons to pass through them.

A superconductor is a material with extremely low resistance to an electrical current. Many are metals or the like which have been supercooled to temperatures approaching absolute zero. Examples are mercury, lead and tin
coz wood is an insulator, where there's no free electrons n thus current pass through the wood :)
By Flowing of Free or Conduction Electrons
300A means that 300 coulombs of electrons are passing through it per second. 300 coulombs is (1.87 * 10^19) electrons, or simple 300C of electrons.
In any electrical conductor which is not a superconductor, there is some degree of resistance. In the process of overcoming that resistance, the moving electrons will disturb the various atoms that they pass by, and therefore will increase their vibration, which on a larger scale is seen as heat.
An electron is electricity as we know it. Electrons flow through a conductable element and that is electricity.
