What is an EMP ( Electromagnetic pulse )?
According to Wikipedia,
An electromagnetic pulse ( EMP ), also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy. Such a pulse’s origination may be a natural occurrence or man-made and can occur as a radiated, electric, or magnetic field or a conducted electric current, depending on the source. EMP interference is generally disruptive or damaging to electronic equipment, and at higher energy levels a powerful EMP event such as a lightning strike can damage physical objects such as buildings and aircraft structures.
What is an EMP Jammer?
EMP jammer is a simple high peak pulse generator. We know current flowing through the conductor generates the magnetic field around the conductor. If we supply current with intervals it generates field pulses on the conductor, the field increases suddenly and decreases. If we apply current pulses it generates high electromagnetic field pulses. These high-intensity pulses induce a back emf in the devices which in turn damages the device.
Caution: EMP jammer may cause irrevocable damage to electronic devices. Use of any emp devices is illegal in some countries. Also, EMP jammer involves high voltage which is hazardous and may cause injury. Please take care when dealing with high voltages and do this at your own risk.
