Can electric fields pass through metal?

Hint: The physical field that is generated by surrounding electric charged particles and exerts a force on all other charged particles is represented as the electric field. It's also generated by a magnetic field. The attractive force between the atomic nucleus and electrons is created due to the electric field. Hence within the conductor, the charges have maximum freedom of movement and there is no electric field within the conductor. That’s why the electric field cannot pass through it.
Complete step by step answer:
Having a large number of the free valence of electrons makes metal a good conductor of electricity. By allowing free electrons to move between the atoms metal conducts electricity. When these conductors are kept in the electric field, the electric field will be zero inside the conductor. It’s a negative feedback process within the conductor.
When there is an electric field within the conductor, positive charges are entirely free to move to the direction of the electric field, and negative charges are entirely free to move to the opposite direction of the electric field. But, these charges are surrounded by their own electric field. The charges that are influenced by the internal electric field will create a field that will oppose the effect of the original field. Thus the electrons are not free to move in all directions at the surface. Hence, if the electrons are in a conductor in an equilibrium state the force upon the electron will be zero.
Note: Inside the conductor, the electric field is zero.
The electric field always is perpendicular to the surface of conductors, beginning or ending on charges on the surface.
The excess charge is situated on the surface of the conductor.
