Abstract

An electromagnetic generator without moving
parts includes a permanent magnet and a magnetic core including first
and second magnetic paths. A first input coil and a first output coil
extend around portions of the first magnetic path, while a second input
coil and a second output coil extend around portions of the second
magnetic path. The input coils are alternatively pulsed to provide
induced current pulses in the output coils. Driving electrical current
through each of the input coils reduces a level of flux from the
per ....etc

The next Pearl Harbor will not announce itself with a searing flash of nuclear light or with the plaintive wails of those dying of Ebola or its genetically engineered twin. You will hear a sharp crack in the distance. By the time you mistakenly identify this sound as an innocent clap of thunder, the civilized world will have become unhinged.

Fluorescent lights and television sets will glow eerily bright, despite being turned off. The aroma of ozone mixed with smoldering plastic will seep from outlet covers as electric wires arc and telephon ....etc

I. Introduction
Current U.S. military transformation strategy centers on information dominance, network-centric warfare, and expeditionary operations. Operations Desert Storm and Iraqi Freedom demonstrated a spectacular evolution of capability in these key areas. Certainly, adversaries learned from Saddamâ„¢s poor decision to face American forces head-on and will increasingly employ asymmetric attacks to defeat U.S. forces in the future. Electromagnetic pulse (EMP) weapons represent one of the most likely and potentially devastating opp ....etc

What is the definition of electromagnetic brake?
A non-contact brake design actuated when an electric current charges a coil that acts as an electromagnet. Electromagnetic brakes are widely used in automated machinery and provide a high cycling rate.

Quote
On trams and trains, an electromagnetic brake is a track brake where the braking element is pressed by magnetic force to the rail, i.e. the braking is by friction, not the magnetic effect directly.

This is different from an Eddy current brake where there is no mechanical contact betwe ....etc

An electromagnetic bomb or E-bomb is a weapon designed to disable electronics with an electromagnetic pulse (EMP) that can couple with electrical/electronic systems to produce damaging current and voltage surges by electromagnetic induction. The effects are usually not noticeable beyond 10 km of the blast radius unless the device is nuclear or specifically designed to produce an electromagnetic pulse. Small nuclear weapons detonated at high altitudes can produce a strong enough signal to disrupt or damage electronics many mile ....etc

Pulse Shape Improvement in Core-Type High-Voltage Pulse Transformers With Auxiliary Windings
High-voltage pulsed power technologies are rapidly emerging as a key to efficient and flexible use of electrical power for many industrial applications. One of the most important elements in high-voltage pulse-generating circuit technology is the transformer, generallyused to further increase the pulse output voltage level. However, its nonideal behavior has significant influence on the output pulse shape.The most attractive winding configurati ....etc

Electromagnetic Pulse (EMP) is an intense energy field that can instantly overload or disrupt numerous electrical circuits at a distance. Modern high technology microcircuits are especially sensitive to power surges, and the possible vulnerability of U.S. civilian computer systems to the effects of EMP has been discussed in the media. EMP can be produced on a large scale using a single nuclear explosion, and on a smaller, non-nuclear scale using a device with batteries or chemical explosives. Several nations, including reported sponsors of ter ....etc
