“I am busy just now again on Electro-Magnetism and think I have got hold of a good thing but can’t say; it may be a weed instead of a fish that after all my labor I may at last pull up.” — Michael Faraday, Letter to Richard Phillips, 23 Sep 1831.

What’s an EMP? Briefly, it is a burst of electromagnetic radiation that results from an explosion, either natural or manmade. It may result from a severe solar storm, a nuclear bomb or an E-bomb.
What are EMP’s effects: The effects are similar to lighting strikes and switching surges. The bursts look like an Aurora and generate lots of static electricity, putting electronic digital systems at risk. To wit (a short list):
DEGREES OF SUSCEPTIBILITY TO THE EMP
Most Susceptible
Low-power, high-speed digital computer, either transistorized or vacuum tube (operational upset)
Systems employing transistors or semiconductor rectifiers (either silicon or selenium):
–Computers and power supplies
–Semiconductor components terminating long cable runs, especially between sites
–Alarm systems
–Intercom systems
–Life-support system controls
–Some telephone equipment which is partially transistorized
–Transistorized receivers and transmitters
–Transistorized 60 to 400 cps converters
–Transistorized process control systems
–Power system controls and communication links
How do you protect a device from an electromagnetic pulse?
“For a Faraday cage to be effective against an electromagnetic pulse, it must block out the entire wavelength of the EMP, explains The Survival Mom.” (You don’t have to be a whiz kid to make a Faraday cage. This post’s links and others spell out the EMP’s effects and what protection is required. Simply understand the principle and create your own cage for your electronic devices.)
Homemade Faraday shield in the works
What is a Faraday cage or Faraday shield? It is an enclosure formed by conductive material or by a mesh of such material, used to block electric fields. Faraday cages are named after the English scientist Michael Faraday, who invented them in 1836.

About Michael Faraday (22 Sep 1791 – 25 Aug 1867), lest you think the Kingdom of God is only a work of spiritual magnitude:
Faraday was the first scientist to realize the enormous importance of the electromagnetic field. He saw in it a reality of a new category differing from matter. It was capable of transmitting effects from place to place,…
Faraday found no conflict between his religious beliefs and his activities as a scientist and philosopher. He viewed his discoveries of nature’s laws as part of the continual process of “reading the book of nature”, no different in principle from the process of reading the Bible to discover God’s laws. A strong sense of the unity of God and nature pervaded Faraday’s life and work.
