Answer:
In electrical engineering, electromagnetic shielding is the practice of reducing or blocking the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs . Electromagnetic shielding that blocks radio frequency (RF) electromagnetic radiation is also known as RF shielding.
