Question

Which electronic appliances can be jammed using emp jammer

Answer 1

EMPor Electromagnetic Pulses are pulses of Electromagnetic radiation that have the ability to disrupt electronic circuitry. High power pulses will destroy electronic circuits and low power pulses will cause circuits to behave erratically. It is this last result that the EMP Attack is trying to generate. The Actual device is small and the small coil antenna is placed inside the Validator. When the EMP device is activated the EMP that is emitted from the antenna will affect the unshielded chips in the validator. The results are somewhat random and may not produce any results but because the device is so small and low powered it is difficult to detect.

electrons "live" in conductive wire. When a magnetic field passes by the wire, it excites the electrons and they begin to move. Once the field stops moving, so do the electrons. This concept is the primary way we generate electricity; using coils of wire and powerful magnets. An EMP jammer follows the same concept; a high current pulse of electricity is released through a single or double loop wire antenna, creating an intense magnetic field that, in turn, excites electrons in any metal in the range of the magnetic field. This creates a large voltage surge in the surrounding electronic components, and effectively fries any sensitive transistors.

There are two ways an EMP jammer can create a magnetic field; either by a very powerful single-pole pulse, or a less powerful fluctuating-pole pulse. Both have their advantages and disadvantages.
eg: appliaces like home alarm system can be jammed through emp jamner...
