What Role Does a Faraday Cage Play in Electromagnetic Induction?

💡 The Answer

• A Faraday cage is a conductive enclosure that blocks external static and varying fields.
• When a changing field hits the cage, induced currents create an opposing field.
• This cancels the field inside, protecting sensitive equipment from interference.
• Faraday cages are used in electronics labs, MRI rooms, and lightning protection.
