E-Bombs generate electromagnatic pulse which destroys any and all electric current running in any particular area it is detonated in. E-Bombs are a national threat and are being sold on the black market for $400 to terrorists. For the place that is being hit, it wipes out all electricity and is said to destroy all of the technological advances within the past 200 years. Basically they generate a large magnetic pulse (with a large coil of wire) which has a lot of current running through it. Then the chemical inside explodes touching the coil of wire causing it to be a moving short circut. When it hits, all current running through any metal or electricity-using object is destroyed. Terrorists in the middle east along with Iraq have been said to be researching this bomb for several years and have become a large threat to the United States. I hope that answers your question
