Can electric fields can be completely shielded using a metal box or metal sphere,
please clarify the concept.
please clarify the concept.

A metal box can shield from electric/magnetic fields by creating a barrier between the outside field and the inside of the box. The metal acts as a conductor and absorbs the electric/magnetic energy, preventing it from entering the box.
The best type of metal for shielding from electric/magnetic fields is one that is highly conductive, such as copper or aluminum. These metals have a low resistance, allowing them to easily absorb and dissipate the energy from the fields.
No, a metal box cannot completely block all electric/magnetic fields. It can significantly reduce the strength of the fields, but some energy may still pass through small openings or gaps in the box.
Yes, the thickness of the metal box can impact its effectiveness in shielding from electric/magnetic fields. Thicker metal can absorb more energy, but the type of metal and its conductivity are also important factors.
Yes, there are other materials that can be used for shielding from electric/magnetic fields, such as conductive fabrics or paints. These materials can be applied to walls or other surfaces to create a shield against the fields.
