If a substance does not permit the flow of electrons,
then it is not a "metal".
A material that will carry an electric current is called a conductor. Conductor materials have high electrical conductivity, allowing the flow of electric charges with minimal resistance. Examples of conductors include metals such as copper, aluminum, and silver.
Resistance is the hindrance a conductor creates to the flow of electric current

In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators. In copper, the valence electrons are essentially free and strongly repel each other. Any external influence which moves one of them will cause a repulsion of other electrons which propagates, "domino fashion" through the conductor.Simply stated, most metals are good electrical conductors, most nonmetals are not. Metals are also generally good heat conductors while nonmetals are not.Source: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/conins.html
Yes, a MOVING magnetic field will cause electric current to flow in a conductor. Conversely an electric current flowing in a conductor will cause a magnetic field.
A substance that lets electricity flow through it is called a conductor (or sometimes, to be more explicit, it is called an electrical conductor). Substances which do not permit the flow of electricity are called insulators.
An electrical insulator is a material that resists electric current, and will not allow it to flow easily. Examples include glass and most ceramics. An electrical conductor is a material that offers very little resistance to electric current, allowing it to flow freely and easily. Most metals make excellent electrical conductors.
A conductor
The opposite of a conductor (conducts electric flow) is a non-conductor, or something that opposes the flow, which would be an insulator.
In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.
A material through which negatively charged particles flow easily is called a conductor. Conductor materials have a large number of free electrons that are able to move within the material, allowing the easy flow of electric current. Examples of good conductors include metals like copper, aluminum, and silver.
