Faraday Bag Faraday bags are made of flexible metallic fabric. It does not allow electric field lines inside of it. So they can be used to block remote wiping or alteration of wireless devices recovered in criminal investigations. They may also be used to protect against data theft or to enhance digital privacy.

Learning objectives

After completing the topic, the student will be able to:

• Explore the concept of electric flux and how electric flux density is related to Electric field.
• Understand and determine the electric flux through any Gaussian surface using Gauss's law.
• Learn to use Gauss’s law to get electric field due to various symmetrical charge distributions.
• Explore the difference in electric field due to planar charge and charged planar conductor.
• Discuss and explore the electric field inside cavity of non-conducting charged body.
