  • Today we will be learning about electromagnetic shielding and why it's a thing
  • Electromagnetic shielding in a real world situation is usually used when we surround cables with conductive or magnetic materials to block incoming or outgoing electromagnetic frequencies 
  • Electromagnetic shielding is when you reduce the magnetic field in a area by stopping the field with things made of coductive or magnetic materials
  • This diagram to the right of me demonstrates electromagnetic shielding 
  • secondary reflection
  • reflection
  • electromagnetic waves
  • transimision
  • absorption
  • But wait why do we even need electromagnetic shielding?
  • The reason we need electromagnetic shielding is because if we didn't have it then electromagnetic interference (EMI) would impact the functionality of a nearby device like a tv, phone, or powerbox.
